I once glued and taped something like 5 of those bottle together for one monster 10 liter water rocket. I decide to test the thing with my 10 year old little brother (it was maybe 15 years ago) on our backyard. I was pressurizing the thing up to 8 bars with bicycle pump and maybe 4 meters long hose when it exploded around 5.5 bars. We both thought that it was the greatest thing ever but my mom was super angry since it was stupidly loud :D
Ha! I have a few old videos myself that end abruptly as my mom is heard shouting in the distance

Yeah Mom doesn't understand because she's a girl. That was a good result! LOL
Finding out that the HPC guy has been blowing stuff up since childhood is the least surprising surprise ever :D

Wonder what the neighbours think when they hear laughter and explosions from your garage (Honey he's talking to the pvc pipes again)
That's some really awesome fluid dynamics and a great use of high speed footage! Great video

Your laugh is like 60% evil genius. You'll get there.

Hello and welcome to the Slingshot channel. AHAHAHAHA!!! Hope you liked it because that's it for today, thanks and bye-bye.
Ben is definitely 100% genius but probably only 20% evil
Watch his Running a Gasoline Engine on Firewood Video at around the 4:08 mark, that's pure Evil Laugh goodness right there.
I don't know if he's married but, if your wife hears that sort of laugh coming out of you, she's probably thinking of going somewhere else for a while to try and forget about the house burning down.
You’re probably the only channel I know of that has stayed very consistently interesting with every video over the years. Keep them coming!

Awesome man! The high speed was cool as sh*t!. Keep that character and energy up! That's what makes the videos do well, people can feel that energy!!
I didn't know I needed to k ow why dogs got up so fast until I seen your video. Thank you.

We've learned that packaging tape may be useful for ejecting stages in a multistage rocket.
I would very much like to see a multistage rocket built out of 2liter bottles.
Something is wrong here: you're having entirely too much fun.
What Is Islam?
Islam is not just another religion.
It is the same message preached by Moses, Jesus and Abraham.
Islam literally means ‘submission to God’ and it teaches us to have a direct relationship with God.
It reminds us that since God created us, no one should be worshipped except God alone.
It also teaches that God is nothing like a human being or like anything that we can imagine.
The concept of God is summarized in the Quran as:
{ “Say, He is God, the One. God, the Absolute. He does not give birth, nor was He born, and there is nothing like Him.”} (Quran 112:1-4)
Becoming a Muslim is not turning your back to Jesus.
Rather it’s going back to the original teachings of Jesus and obeying him

@@ahmdabdallah5811 I think the Holy Bible would be a good teaching for you. Quran is none of the 66 books in the Holy Bible .
Philip Webb incorrect! He is having exactly the right amount of fun!
Exhaust flow is subsonic, wonder if you could fit a de Laval nozzle on to get a bit more oomf out of it?

For many a mere fraction of a second or so, it WAS supersonic!

It could hit Mach 1 if the flow was choked at the nozzle, but it can’t go over that unless it expanded afterwards.
These are some of the coolest slow motion shots I've seen too date and the shots demonstrate some really interesting things too. Thank you so much for sharing!
I really appreciate that you make predictions before you do the experiments and are willing to leave those in during edit even when you're wrong. Kudos for showing good scientific discipline.
The brighter and lighter the colour of the flame, (the blue flame front) the more stoichiometric the burn is
Wow, it’s been a couple of years since I’ve consistently watched your content. Seeing this and your Starlite video makes me wonder why I stopped. Your videos have done wonders to keep alive the interest in STEM and the way things work alive in me. Thank you.
Now I’m curious if something as simple as a rubber washer on the bottle launcher would keep the bottle where you want for the ignition point.
Ahhh, loved those slow-motion shots!
This video reminds me of the times I made potato cannons 'sing' by filling the chamber with a rich butane/air mixture, keeping the barrel empty, then hitting the ignition. The one that made the coolest sound was the straight-pipe cannon measuring about 4" dia x 72" long. Too much fuel in the mix = slow burn = loud, twangy, bassy howling.
“More on that later”? I had to double check I wasn’t watching a Practical Engineering video.
I'll be honest I'm enjoying this more because you seem really into the project and really happy. Also that's cool. And dw just add more tape. Anything can be fixed with more tape.
Place a pressure gauge in the wall of the bottle with a “tell tale” pin which will show the maximum pressure achieved during your various fuel to air ratios as well as with the differing points of ignition. Great video. Looks like loads of fun.
Awesome video. I love the slow motion, it really shows what's happening. Also, thanks for plugging my tutorial!
Your adrenaline fuelled laugh got my miserable fizog to grin like a Xmas day child unwrapping prezzies. Thank you. Oh, the science stuff (witchcraft) was interesting too!
Famous last words, "I did not mean to hit the trigger..."
The slow motion cameras have sure changed the way we look at so many things !
Highly entertaining ! 😊
Thanks for sharing and take care. 👍
A couple of months ago I watched this video knowing literally nothing about rockets. like, absolutely nothing. But, I thought this was the coolest thing and I was determined to create a rocket engine. Soon enough, that goal changed into creating a full on rocket, and to get it into space. I started researching straight away, and I found another one of your videos on the hybrid rocket engine. I immediately started working on it, and It actually worked! Something you should know about me is that I never, and I mean NEVER finish projects. I always start them, but move on to something else. So for me to build a working rocket engine, that’s a huge achievement. I started doing more research, and I started looking at liquid fueled rocket engines. I started learning about things like the turbines, oxidizers, fuel pumps, injectors, over/under expansion, and a lot more. I am now currently working on a liquid fueled rocket engine, and it’s going great! I owe it all to u. My goal right now is to start my own rocket company, like SpaceX. I know it sounds crazy, but I’m working at it. It’s weird to think that all of this never would’ve happened if you didn’t make this video, so I just want to thank you for making my dreams come true.
Glad to see you're posting again!
First 19 minute CZcams Video I haven't skipped forward on...So entertaining!
I've been watching you for years, and everytime I get a notification, I can't wait to get home and watch them! Great content!
I've learned more in this 20 minute video about science than I have in 4 years of high school and 2 years of college! Really loving the videos lately! Keep up the great work!
The reason it burn faster when at the back of the botle is because the fire starts all the way back in the pvc pipe, the air fuel mixture is accelerated into the botle at speed before full ignition, causing turbulence.
(Similar to how a diesel engine with a precombustion chamber works)
Mate, you're 100,000,000,000 ^ 100,000,000,000 more competent, experienced, interesting and humble than the majority of so-called, self-professed "science" channels on YT. Same applies to Destin @ Smarter :)
This video has a lot more of you speaking in real time rather than narrating in post. Your delivery sounds really natural this way.
I've been making potato cannons for ages with that technique. Tape works brilliantly, but to get them to last a long time you want to make sure the direction of flow won't be going under the seam.
(videos on my channel of them btw)
do you reckon you could make a baffles in the bottle while keeping it see through so you can demonstrate how a firearm suppressor works? It would be quite difficult but it would be awesome high speed footage
Check out smartereveryday he did that a while back actually
I'd like to see this on one of those weird 3 liter bottles.
I remember that smartereveryday dude did some ignition tests to analyze the shockwave but it was for a potato cannon instead of a rocket. Still, it might be useful to compare notes
explosions make me happy too, keep up the good work! :)
Cool experiment! The high speed footage was really good. Beautiful colors. I'll take same mashed potatoes with that gravy. 😄
I absolutely love how much you can learn with tests like this and a good high speed camera! Thank you!
The best youtube videos are made when the youtuber is enjoying what they re doing in the video.
This is one of those times! great video!
Thrust tests and thrust graphs
with the 3 configurations please. 😳😳
I love your videosI 😍
I know, right?
Love these videos, especially when seeing your genuine excitement to things you find cool!
Brother, your videos are really unique and slow motion is seriously satisfying. Greatly educational
What I love most about this video is how you are so much more candid and genuine. It's like seeing the real you and excitement
Absolutely love your videos. That slo-mo was awesome! The flame front and jet out the nozzle was super cool. Thanks!
I finally got a notification from youtube again and started watching your older videos as well. I got the idea: can you do this with wood gas as well? It'd be really fun to see some of your projects combined!
You are so giddy in this video, it is obvious that you love this, also your excitement is quite contagious. Great work as always
10:40
Ah ah ah! It does show something: You made a one pulse pulsejet.
Excellent! Your true joy and excitement is contagious.
Thanks for the link from your sponsor. Seriously, I was searching for a good idea for Christmas, and this is going in the list! Also, I love this video!
"So anyways, I just started blastin." --Nighthawk off camera, probably.
I didn't know I needed this until I watched it. One of the most entertaining videos I've seen in a long time, thanks!
Thank you so much for the absolute joy you have brought me through the years ☺️ you are one of the reasons I am who I am today! Keep on experimenting!!
Great video! Looks like you had fun :)
As a long time subscriber I realize all your videos are with great content over a wide spectrum. I like what you upload very much. Looking forward to the next video.
Awesome slo-mo shots! Thanks for the video.
I love that there's not too long of an intro. Thanks for keeping it interesting.
That footage is GORGEOUS!
I love seeing you get excited with each result. Such genuine happiness in your work. Keep it up!
One safety tip I’d give is have an old table cloth or towel hung in the path the projectile is flying so it will hit that vs the wall. That should distribute the energy so the object will be less likely to bounce back at you.
Table cloth might be a bit too light.
These fire colors are absolutely beautiful!
It really makes me happy seeing you having so much fun in your video! :)
Havent watched one of your videos in absolutely ages! The nostalgia is real
The color of the flames are beautiful!
I really enjoyed this.
Good research. Well planned and good production quality.
Good job and keep up the good work.
Thanks
this was beautiful. fire, explosions, theoretical uses in extreme hobby bottle rocketry...
also, i've never seen him so giddy before, a nice change of pace.
It's funny how you're mostly composed and calm, but in this one you can feel the excitement :D It's great!
wow, that colour on the second flame is beautiful. the one that goes back into the bottle again. The initial cyan flame is pretty nice too
I love how much fun you're having man. Fun vid for sure.
Your enthusiasm always puts a smile on my face
A couple years back I built a propane torch pop gun based on your project. I used it as a prop for my Tusken Raider Halloween costume, and it's pretty much the only diy science project I had seen all the way through in a long time. Looks like I need to get back into this stuff again, thanks for making videos!
As a fellow scientist i love watching your process! very well done and methodical!
I love your videos, always really interesting and you can tell you have a real genuine love for what you are doing!! Please keep on make awesome videos!!
great work man! I just discovered your channel and don't know how I haven't stumbled across it before, keep it up!
Fantastic video! I can't wait to see what your further experimentation shows!
Super cool! Thanks for sharing.
Such a great video and stunning shots!
Always bringing the best visuals. Awesome
14:42 now that was what I was waiting on 💥💥👍
Great experiment and slow motion footage. Thank you for continuing to put out interesting and quality videos. Your channel is only one of three I have the bell clicked on. The other two are Lil Bub and The Wolfe Pit. I’m always happy when I see you uploaded something. I’m checking out the sponsor of this video to support your efforts, being the holiday season I’m buying something for certain.
Good job, man! Amazing video, as usual!
Nice shots! Amazing! 👍🏼😃
dude i love this type of video! the whole process of your testing 😎 more like this!
14:44 laughs like Jörg Sprave
*Let me show you its features!*
The ignition point being at the very end of the bottle and the highly vigorous ignition shows precisely why gun barrels work so well and why bullet casings are designed the way they are with their primers.
He’s like your cool uncle... I have never heard the most genuine “having fun” laugh ever....
I love these experimental videos!
The colors at 17:44 are simply stunning! Most excellent video!
Great visuals, I'm already binge watching lol
Very good. Real science ! Thanks. Learned a lot. Lots of fun too.
Beautiful slowmo shots
@NightHawkInLight my name is Gonzalo, I actually used one of your rocket launcher mortar videos and used it for a project for my engineering class back in high school. Best believe we got an A so I thank you. Just know we could bring it to school but not fire it obviously. We had recorded a video and shocked the class in awe with a frozen frame where it looks like a bright yellow Christmas tree like fire was coming out the end of the launcher. My engineering partner and I decided to visually advertise it as a rocket launcher from the shoulder rather than a mortar. We wanted to add a strap but that never happened which is okay because It was still awesome enough shooting it without the strap on the shoulder with its military green color and red button from the barbecue igniter we bought from the internet. In investing extra time even after the project back in high school I wanted to improve it and make it more powerful and did a lot of tests. I have tried different isopropyl alcohol percentages and the highest I found was around 70+%. I noticed the higher the percentage was the easier it was to set it off. I slowly perfected a method to introduce the vapors of the liquid and I also tried different bottles, smoother ones.. I want to one day maybe add fins with the limited space I had, perhaps make a fin mechanism inspired by ballistic missiles and rockets shot from different military rocket launchers like the famous RPG or the AT4. I found the best results for the "bottle rockets" is to get the biggest one that can fit in the launcher with a smooth outside layer with no ridges for hand grip for less drag and the static short circuit as back in the bottle as possible had best results. Now because of your launcher back in that video, its been pretty slow right now but I'm trying to develop an actual air-soft rocket launcher that is simulates a real one but still being safe enough for the sport. I found a void for that market because all the launchers for sale at the moment use basically a small nerf football that or a clump of bb's flying into one spot. So i have come up with a couple designs in theory that should work. I don't care who patents or gets it on the market first. The air-soft sport deserves better simulation and the launchers today are not very good. In regards to this I had called some of my old engineering class friends to help me on the project as well in an effort to create something feasible, some of the ideas seemed promising and some new ignition ideas that would function from the inside of a bottle rocket or eventually an air-soft rocket using the one we had created back in high school as a base to demo or showcase where or how our different ideas would be applied. I love rocketry and explosions and to be honest you were a big influencer of that when i first saw that video, from a science loving perspective obviously but I wont lie i'm kind of a pyro-maniac. Thank you for the videos you make they are very cool and keep doing what your doing.
Yours truly - some guy who got an A+ using one of your mortar video tutorials. Much love
Beautiful colors! Subscribed.
Amazing that you are back!!
Ben having way too much fun. Your giggling is awesome.
thats got to be the coolest thing I've seen in a while!!!
Very interesting! Love the slow motion video. :) Keep up the great work!
