My first commtest submission as a physics student!!
The water has an insane amount of kinetic (moving) energy as it reaches the blob. As it hits the inflated side of the blob, it transfers its kinetic energy into potential energy. This potential energy travels across the blob from the inflated to the deflated side, and the object on the deflated side is propelled upward with equal energy to the bag of water as it fell, quickly turning back into kinetic energy.
Now, this is only in an ideal world. Due to the laws of thermodynamics, energy is lost during the transfer to friction, sound, etc.
Therefore, the ideal length of the blob is probably even shorter than the one used for the boat, I would say roughly twice the width of the bag of water. If you look at the “slowie” at the end of the video, you can see the bit of inflated blob between the water and the boat. In that distance between the falling water and the object, a small amount of energy is being lost.
That being said, if the object is too close, or the blob too short (less than half the water bag’s width), then the water bag will either hit the object or the blob will not have enough space inside to re-inflate the other half of it, immediately compromising the spring force of the blob that makes watermelons fly to outer space.
Hope that sounds smart enough :)
If I wanted science, I'd get it from Gaunson. ;-)
Here I’ll dumb it down for you, air move, and thing go up
@@alspacrat you’ve got an excellent point and I can’t argue with you… lol
@@azaquix8711 that’s pretty much it. You forgot one part tho: thing go up
Bro you sound like a true genius dang good job
So the blob works on something called impeadance matching. In this case it has to do with how effectively the mechanical shock of the water bucket can be transfered to the air inside the blob. Then the compression wave of the air has to match up with the fabric on the other side to launch the items. The interface from impact to air to launch is an impeadance matching problem. The best way to find out the proper impeadance matched air fill is 3d modeling. This modeling is like what Mark Rober did for the trampoline.
Dammm 👌🏻 you brought a tear to my eye 🥺 and you only have 20 likes! People can be harsh :/ though you posted this 8 hours ago. Still I love me a good scientist 🦄
@@-PinaColada- ok
Question for the physics masters. What is the impact of changing the medium in the blob? I assume there is an ideal fill amount based on displacement expected. But assuming same volume in blob, is water or air better? (Assuming fabric strength was not a concern)
@@joeb1kenobi600 changing the medium would make a massive difference. I am being too lazy to calculate but the resultant impact would be determined by the impact force + weight of the medium + (a whole bunch of other things). Best mediums would be lightweight and have low viscosity so the force gets transferred across quickly and efficiently to the empty area/weighed down side. aka: in this case air is better then water.
Think of it as a balloon filled with air/water/honey, squeeze it and release. fastest to be squeezed/return to normal balloon is best medium to use in the blob.
(hope that kinda makes sense, PS: ideal amount would vary on medium+dimensions of blob)
@@shadowraven137thanks for the great explanation. My twins were wondering the same thing and your explanation was clear and understandable. They picked up on your explanation quickly. Thank you.
Crane operator: "this is the weirdest jobsite I've been on." 😅
"But best"
probably his easiest day ever
It’s still a good one
But imagine how fun, relaxing, and easy that pay day would be compared to his regular work
I would have thought the Rexy one was the weirdest to be fair lol
Y'all need to launch a piano. I can't wait to hear what it sounds like when it hits the ground.
Ps2
Here's a text preview: DROUNNNNNGGGGGGGGG
They already dropped 1 on a house...
Or a drum kit lol
@@SireSquish 🤣 Something or exactly like that 😂
I happen to go to the camp where the blob was invented, so here’s a little story about it’s creation!
The camp’s founder, Tex Robertson, needed a temporary roof for the archery shack, but didn’t have much of a budget, so he bought a tarp container from the government’s war surplus. I’m not sure, but I think it used to store gasoline. Anyways, to move the blob over to the archery shack, he pumped it up with air so he could pull it. While he was pulling it, his friend (I forgot his name, but I think it was Patrick) jumped on it and found the bouncing it did was pretty fun! They started experimenting with the blob, and found that it worked best on a lake, so they put it on the lake and made a little diving platform to jump onto it, and later put a “sock” over the black rubber blob, since it got very hot in summer. Some changes have been made over the years, but it’s remained about the same since it’s beginning.
Need to get Mark Rober to design ya'll a high energy, high velocity capable blob. Since those are technically designed for humans. Need like a kevlar ultra tough stitching Super Blob. Challenge initiated!
Richard G great minds think alike.
I second this
Mark Rober, Destin from smarter everyday and HR = Epic colab!
yessssssss
Yes! That's a great idea!
2:06 that footage was amazing!
That boat flip was insane! The bag acts as a see-saw, a weight pushes one side down forcing the other side up. The main difference is the air. The smaller bag should send items higher as there's less space for the forced air to travel to making it more efficient, though there's more of a risk of it popping. Using the principle of conservation of energy you can roughly predict how high the object will go, though you can't predict how cool it will look in slo-mo!
Also, would it be ridiculous to play noughts and crossed with the blob, basketball or javelin style?
I MARK my territory as a Mark. Never felt so much attention from a CZcams video before. I feel so wanted. Good job guys. Love your content.
I know how you feel, someone gave me a shout out once, that was nice. 😊
Fun fact: The name Mark comes from the same Latin root for Marcus, and means......
Mark.
Makes me think that there should be a battle of the Marks (call it mark of the Marks) like there was just a battle of the Joshs'
@@gregorybower2759 Get together, rent a huge office building, and have a huge YT streamed game of real-life Amongus with nothing but people named Mark.
Hi Mark
The smaller blob can hold less air in it than the big blob. However, the size of the water bag is the same. What this means is that, proportionally, the small blob can move more air over to the other side of the blob quicker and harder. This also means that the water bag cannot push out all of the air underneath it without fully inflating the other end. This gives the smaller blob a much more forceful launch; however, it also causes the small blob to burst pretty much every time.
As for the Big Blob, you can see in the slo-mos (2:14, 4:40 and 12:42) that the water compresses the blob, then the air has to travel across the length, which allows energy to dissipate before it reaches the projectile. The larger volume also allows for the air to adjust and compress to the sudden 1,000 kg of force. Overall, this happens in a fraction of a second and does not dissipate a lot of energy, but the compressibility of air allows it to absorb the impact like a spring. This heats up the air, which is a loss of energy. Again, this loss in energy is very small, which is why the Big Blob still performs spectacularly.
Edit: TL:DR More air can absorb more energy, so smol blob is better. The air absorbs a small amount of energy, so the difference is small.
I'm also going to add that the larger the surface area of the projectile in contact with the blob then the harder the push.
Pin this man
Also, the size of the projectile matters. If it is too close to the point of impact, you don't get the full force. So certain objects can get more force out of the larger blob just because their size makes them too close to the point of impact. Basically, the small blob works better for smaller objects and puts out more overall force, while the larger one launches larger objects more easily and efficiently.
Damn
Fill the blob with water for less fluid compression
11:35 watch in 0.25 speed, there is exactly one frame where Herron's sunglass come off, float, and vanish x"D lmao
They cut it
08:30 for the question "which blob is better, the big or small", the smaller is better because the longer it is the more energy is lost, so to answer the question, smaller is better, plus I'm in late to this video but keep up the great work
I have to say, I stumbled across HR a few years back, and I have been here since. No matter how long or bad of a day it has been, these videos get me back into a good mood, laughing and having a good time! Thank you guys!
HR Liked that*
Same
My mate sent this to me. And then I subscribed. I appreciate the welcome. And I am watching this in the morning after getting up with a screaming toddler. Cheers.
Finally some recognition for us Marks!
The HR boys should go to a lake with the blob and launch themselves. Seeing Gaunson fly through the air doing science with Gaunson would be a classic. God bless guys
In sted of sitting object on top, push the end inside itself and put objects in the pocket. They will shoot out like a cannon
Haha yes, i literally just said the same before scrolling down. We used to launch crap across the cafeteria w ziplocks back in HS.
Now they need to team up with Mark Rober again to create the biggest, baddest, scientifically optimized blob like they did with the trampoline
I agree. Do the water worm and push it inside itself. Put a melon in and see what happens
Ooh! And set up targets on the other end, see how close to a bullseye they can get with different objects!
Yes perfect. I hope the guys see this
Let’s get Mark Rober back on the show to help make the most durable blob ever. Then start throwing some really big/ heavy stuff around.
Destroy things with the HAMMER! BEST videos yet
Mechanical aerospace engineer here.
What is happening is an impulse. Which is a transfer of power/energy in a short amount of time.
You are taking the momentum and force of the water and transferring it as fast as possible into the object you are launching.
The size of the blob ONLY matters in the direction of the energy transfer. Therefore if energy is only in the X axis, the Y and Z axis don't matter.
It can be simplified like a seesaw but where the fulcrum. The longer the seesaw the greater the force transferred.
If 1000kg impacts due to gravity that's about 10,000 N. Multiply this by 10 meters to get 100,000 N*m torque. Then the object being launched you divide by that length from fulcrum, say 1 meter, and divide the mass, say 100kg. And that object is being launched at 1000 m/s^2 aka 100 Gs
Love your explanation. Am I correct in saying their calculations to determine the height of the rubber band ball is incorrect? If I calculate the height I get 89.82m.
@@leadslinger possibly. More information about the rubber bands is needed to know their mechanical properties it that’s probably close
@@daddylaugh1983 I agree with you , However I meant if I use their time of 4.28 seconds I get a height of 89.82.
I feel like I have to suggest this:
Can you Line-X the blob and launch a car with a van? 🤔
Just................ ah, what the heck, I second this motion.
Hmm, two blobs. Cover one with Line-X and wrap the other one with Gorilla Tape. Who will survive!?
YESS!! This is amazing
Really hope they see this
Not to be a party pooper or anything, but if you cover the blob in Line-X it will become solid and won't be able to launch anything. If you dropped a van on it it would crack and break.
I can't help but feel as if I have been summoned
Surely you are the chosen one!
YOU ARE A LEGEND!!!!!!!!!!!!!!!
It's you! The Hero of Kvatch!
How good
You're about page says "Joined 12 Jun 2021" tho 🤨
Was it higher than the trampoline launch? Looked incredible boys! Thank you so much as always you bring such joy!
"Hello, Perth Motorplex"
"Hi, we have a youtube channel and we would like to rent the track to drop 1 ton bags of water on an air blob to see how high we can launch stuff."
"Is that it?"
"No. We also have a golf club the size of a small bed that we've attached to a truck and we want to see how far we can launch stuff."
Hey! Thanks for the shout-out to all of us Marks!
Thats p cool honestly
Jesus Christ love’s you all and you too marks out there
Mark's rise up
@@Mark-cp9tc Jesus and god are fake
Another mark joins the reply section
The Statue of Liberty is 305 feet tall, _including the massive base._ These absolute madlads launched a rubber ball 40 feet higher.
Wait seriously
The HR team had better see this comment.
That's gotta be their tallest launch ever. I would love to be wrong
The statue of liberty is much smaller than people think.
Dawn spoiler alert. Last time I read comments while watching lol
To show you the power of flex tape, I launched this boat in half.
To answer your question about bigger or smaller working better; smaller works better. Air has a particular amount of compression per kilogram of weight applied. That compression absorbs some of that energy. As you increase the air volume, more energy is absorbed. In exact same environmental conditions the larger blob will absorb more energy due to air compression. You could actually measure how much energy dropping the same weight, from the same height, on the same object; just use different blobs inflated to same PSI. Use the height difference between the two and you can calculate how much more energy the large air volume of the big blob absorbs.
Idea: Build a giant marble track for a giant marble at the tower
Million dollar idea, if it didn't cost that much
Or maybe a regular marble track that is as tall as the tower? 😮
@@lospereye I thought that would be harder 🤣
Using bowling balls
@@euanmcdougall1917 it would be a lot harder to do because you have to find a way to stop it from falling, what I suggest is get a bunch of PVC pipes and wrap them around the tower and tie them to the tower with zip-ties and whatever. and boom, and use a half ball or pool table ball as the marble or normal marbles too.
The blob is full of something, and things when dropped on it make other things go high. - My only form of education is Science with Gaunson
yus 44th like 😉
It’s filled with air :/
Dude, if they pin the most fun answer, you got it man!
So true so true
@@masterSFR It's water, I think. Re-watch.
I love the flying camera slowies, and how much fun you are having.
6:05 WOOOW was that are biggest ever anything XD 😆 I'm dying that wow was so powerful 🤣
So.... No one's going to weigh in on how Ruthie nailed the landing? I mean, she crushed it.
Lol, ya literally 👍😂
fax
You know I never noticed that but you're right and also was watching the slowie when I read this she totally nailed it two flips and landed on both wheels
Does anyone else love how the bike landed wheels down
For sure ... Ruthie landed that one even though she lost her hair.
For sure, Ruthie riding the bike rodeo style and landing on the wheels was the highlight for me
ya she hit the landing a little hard but the stunts were straight on
Yessss🤣🤣
How good!
10/10 landing
The little blob is better because the energy doesn’t have to travel as far before it gets to the object your launching so it has more energy pushing it up
Ruthie did a triple flip and made a perfect landing on both wheels.
First boat ever to do a double roll and make a perfect landing.
You guys just made history!! Congrats!
"Why would anyone else... do this?"
That pretty much sums up HR right there.
A catching challenge off it love your work guys
The mechanics of the boys *"shorter vs. longer blob being more powerful?"* question:
In a nutshell the shorter blob has the most potential to transfer the energy best, since air can be compressed; the less air available to compressed the less potential for energy transfer loss. The sooner you can compress that air to a point it starts resisting compression the better. The vinyl itself also has a bit of stretch, so the more surface area you have stretching (thus alleviating pressurization) the less bouncing energy you'll transfer.
The only reason to use the larger blob is to have less chance of it popping, because you'll get a more gradual transfer of the heavy water to the heavy boat, giving the blob a little more time to stretch and transfer that energy. Giving it time to stretch is comparable to our skeletal muscles, if you try and do the splits by dropping to the floor you're going to tear something, however if you stretch for a few days you'll do it no problem. It's just like that only on a timescale of nano-seconds.
Big brain
Massive brain
@Caleb Helms I knew someone would comment that.
@Caleb Helms Ya damn right!
You've done a lot of crazy stuff in the past, but that boat was absolutely bonkers
Would love to see blob vs vending machine or refrigerator!
Scott: “Atta girl Ruthy!”
Also Scott: *kicks Ruthy’s head in*
Hmmm ... I'd love to see a washing machine, a dish washer and a fridge each launched with the Blob :D
that crane operator must love you guys! best day at work
Pritty sure the blob will get ripped cause of the corners
they should also should launch a microwave microwaveing a microwave
Hmm I’d like to see a slowy of Ruth riding the washing machine, dishwasher and fridge all launched off the blob, how good
Semi truck
The smaller one is a lot better for smaller items, but you can get more trajectory from the big one with less air proportional for the size it will make a lot more pop of the blob. The big one can also have bigger items like the boaty, so I would pick the big one with a little less air
Weird Free Bike Challenge today, but Sam shredded it!
You gotta do a shirt with a silhouette of Rexxy and all the Tennis Balls flying off the Blob! Killer video!
@G boy G man p
We need Mark Rober to make a Blob
Y'all should go on the blob. In the water of course. As the finale, Highest flight gets the point
Loved the Mark-related shout out.
Thanks guys; your vids are always a blast!
This is Marky Boy shouting right back at you guys, and to all other Marks out there Hello from England. #How Good
Back @ ya!
At 6:32 you can actually see a rainbow in the explosion of water, great elastic ball Launch. Phenomenal!
Blob size: It's more about how much air is in the Blob. The ideal amount of air, would give you an internal Blob pressure during the impact, that is just below the popping pressure. Also, the farther the items on the Blob have to move while still in contact with the Blob, the longer the acceleration time will be. Ideally, the items should be place on the Blob while partially deflated, and then the Blob aired up to the point that the items are just barely lifted by the blob.
You can always ask the company that makes the Blobs, to double the fabric thickness. :D
Best thing to watch with lunch on a day off from work. 44!
“Why would anyone else ever do this?” Herron says with genuine confusion and concern😂😂
Mark Rober needs to get in on this and send something to actual space
"Mark" Robert ;)
The freaking boat did a freaking 720°!!!
That rubber band ball got sent to the stratosphere
the bowling balls was the best last time...they just sounded pure evil coming down..you guys made 2020/21 better
"Something is going to happen" Well, that is an accurate statement.
Something always does..
Honestly, we're at the stage now where I see the Eternal Watermelon and just feel fear from the mere prospect of it popping. I can only imagine the fetid, fermented horrors contained within.
Do you happen to know where the Eternal Watermelon originated? I searched a bit and am not having any luck locating it's origin story.
@@CookinWithSquirrl yuss me too
wait... it cant be the same one. they cut the original one open after the drop to see what happened to it. i'm not sure how long they've had this one. but i think its new
@@CookinWithSquirrl it was a video from a year or two ago where they lined things with linex and dropped it from the top of the tower onto the street, and the watermelon not only didnt pop, but bounced really good. i do not remember the name of the episode
@@zevo9314 thank you!
Best flipping unexpected ending ever my dudes!!!! Best vibes to you guys, keep it up 🔥🔥🤘🏽🤘🏽
That is by far the strangest way to scuttle a boat that I’ve seen, but it’s also very effective

The only thing worse than 1000 pounds of water
"could this be the highest a melon has ever been launched?" two words punkin chunkin
That's the first thing I thought of when he said that.
I thought those are more for distance though? Height is a side effect of going for the longest distance possible. Or? 🤷
@@blazer6248 yeah. To make something go really far, you have to get some good lift under it.
@@blazer6248 yeah, mostly for distance but its not going to go very far if you shoot it at a foot a above ground level
Are Pumpkins melons though?
It's not about the size of the blob, it's about how you use it...and launching stuff into space is a heck of a way to use it!!
Imagine being a crane operator getting called out to the motor complex, thinking your moving cars or something, then get to work with HR.
Blobs have sweet spots at both ends as far as incoming and outgoing mass placement for determining angle of launch. The length and pressure of the blob are going to determine the energy transfered through the pressure wave to the projectile changing it's distance along that launch trajectory. There will be an optimal solution where the graphed curves intersect between pressure disapation over distance and wave reflection impulse spike. Good luck.
Yeah I was gonna say that eh.
Yeeahhhhh science
You beauty
@@bildoparks420 well I did just get my science with Gaunson shirt. It was inspired.
11:35 Herrons excitment scared the sunnies off of him
You guys should make a video about Dropping a Fridge on Bulletproof glass
1:43 SO CLOSE!
3:56 That lil hop
The way the blob works: the water landing on the blob decreases the volume on the back of the blob. Since volume and pressure have an inverse relationship, the air pressure on the back of the blob increases and moves the air to the front. The movement to the front decreases pressure and (inverse relationship) increases volume, bouncing whatever is on it.
Thank you 10th grade chemistry.
P.S. I got a B on my final so there is a 20% chance I'm wrong
Good description, but that’s not chemistry my friend. That’s physics. 😂
@@McPlayer8t two sides of the same coin
or rather two sizes of the same coin
If that's physics then I feel like I should've gotten a better grade on my test!😂
Yes but also a displacement of the air inside
It's actually basic science. Not physics or chemistry. Your just displacing the air inside the object. Just like dropping a small rock into a cylindrical beaker, the rock cause the water to raise because it is displacing water
“You don’t wanna blow it out the back end especially when they got melons” thought this channel was PG 🤣
If you know what it could mean, you've grown past the need for PG
I feel like you guys should make a blob out of Kevlar so it doesn't rip and drop some massive things!!
It would let all the air out
Kevlar isn't airtight.
This is some of the best stuff to watch when you have insomnia. Thanks guys I love ya!
5:51 we need an uncut version of that shot. No other shot gave that height justice.
This is like Hollywood level stunts right here. With a little CGI, that slo mo shot of the boat could look like a huge wave flipped it or something. The blob is a beast!
I can't believe that Ruthie nailed the landing on her bike.
never thought i'd witness a boat doing a double barrel roll off a blob ,well done lads :)
Guys you have to go big and you know it! do it HR stile and launch a plane!
YESS do it!
100 likes on this comment and you have to do it!
Do It! Do It!
Well, this is awkward...I've never felt so important
*round of applause as you enter chat* HEEEYYYYYYY Mark!
3:50 brings back horrible memories of Jimney Brimson and Landon and the melon cinematic universe
Impressive! Never a dull moment with you guys. I got a great laugh!
I just love their enthusiasm, it makes me happy that these guys can be so happy.
Keep making people smile✊
10:35 If you’re here just for the boat
This is also my favourite video that you guys have made so far.
"Why would anyone else do this?"
Best question of the year.
The fact the boat did a double barrel roll and landed was fantastic
Yes that was impressive, especially when it landed right side up for about 4 milliseconds before breaking pretty cleanly at the hull.
Haven't finished watching the video yet but who else want to see them launch in the air and into the water👀👌
At a lake or soemthing👀
Don’t you know the crane owner/op enjoys his day every time the boys from 44 give him a call.
I shared this with my good mate Mark Jones, performance poet extraordinaire from Devon, UK... had a good laugh! Thanks guys! I've been pushing him to subscribe like I am. :)
Now that's one flying Dutchman of a boat if I've ever seen one. Maybe a Kevlar blob will solve the blowout issue
My thoughts exactly! They could launch bigger things with a stronger blob
I want to see them open the LINE-X watermelon at some point, i'd imagine it does not look pretty in there.
the blob manufacturer must love you guys.
haven't seen ur vids for 6 months... nice to see Rexi 's still alive 😁
"Was that our biggest ever anything?!" Haha brilliant
6:06
Fax.
You should try stacking rubber-band balls one on top of the other like in a previous video you guys did back in the tower, this time with the giant blob!🤩
How do you suppose they get them to stay together? Maybe a larger rubber band that would snap on impact?
You guys shoulda put Ruthy in the boat!
Also I'm not a scientist but I know the heavier things get the bigger the blob you want, I'm sure there is an Air to weight ratio suited for these blobs.
Whoever y’all got to build the trampoline should build y’all a heavy duty blob
Love How Ridiculous went from dropping stuff to sending them to Mars! 😂
THAT WAS AMAZING thanks fo making my day fun
Liar haven’t even watched this yet
We love our new merch...thank you guys so very much. 👍 ~Marz
I got a merch idea cut up the popped blob prices and stitch them to shirts I think it would be epic!
