Yes
ok
how did you write this 4 hours ago but upload 3 hours ago
Absolutely yes!
The comment button is gone for some reason, but I can reply here. 2:16 made me chuckle

I love how you could have just used lbf-in or N-cm but no, you chose to mix metric and EEU like a maniac
lol
Hehe what

Yeah I cannot stand this measurement but it was for simplicity of the length of the opener
1:20 he said newton meters instead of newton inches accidentally. Even he can’t handle how cursed the unit he just invented is
Newton meters are normal
@@aarondroid1595newton inches is the cursed one
97 Newton meters is a lot of force just to open a bottle.
@@sage5296then use Newtown centimeters

As Archimedes, said, “Give me a lever long enough and a fulcrum on which to place it, and I shall move the world.”
Archimedes never said that, he didn't speak English!
@@zeruzio1345how do you know, you weren't there
But could he open a bottle of pop with a banana?
@@zeruzio1345even if he didn't speak english, they can still translate from whatever language it is he used
@@AkiraS.A.Zthe joke....
I like how he glued multiple bottle openers together instead just gluing a long rod or sheet of metal lol
Fr
It's for the natural bottle-opening force they add. A rod doesn't help!
@@GoPieman a sheet of metal would have enough weight. That, or a long enough rod would still let the banana get enough leverage.
@@NigelMelanisticSmitha rod isn’t infused with bottle opening power it wont work
@@drkclshr skill issue. Clearly you aren't German enough to realize that *everything* is infused with bottle opening power
Homework: How many bottle openers need to be glued together so that their weight alone is enough to open the bottle without that extra nudge?
It would be a good I'm class experiment to show leverage forces
between 8 and 9
Since units of bottle openers are discrete, the answer is 9. Units have to be discrete because we don't know exactly how much mass comes from the glue vs the bottle openers. Since other assumptions are in play though, just round to 2 decimal places, should be fine.
@@ancellery6430when seeing your comment my dumb brain thought "7" 🥴

You gave me an idea for an automatic bottle opener. It totally isn't lots of bottle openers glued together, I swear!
Just add a counterweight on the end
Make it long and of Tungsten and it should work
@@jordanguelbert7754 tungsten cube
As a bartender seeing those bar keys glued together like that was horrific.
:)
I've got a lot of respect for people who study math and sciences, you did a great job explaining but it still went over my dumb head lol
Yeah, for me it's a tough balance of deciding what to explain vs leave out because everyone's backgrounds are different, so I wouldn't blame yourself. I appreciate you taking the time to try, that's all that matters!
Metal sticks together strong
@@zirconthecrystal1150banana fiber stronger
@@JaDroppingScience as someone wanting to study physics next year, pls feel free to do advanced calculations. to me it would be very interesting and helpful
You need to take a course in statics to understand it, it's ok
I fucking love physics. The serotonin my brain receives listening to the scientific and mathematical explanation of a banana opening a bottle is indescribable.
wow the literal inertia of the tip opened the bottle. that's impressive and mind boggling what true understanding of physics can look like
N-in as a unit makes me physically uncomfortable
Boooo I didn’t get this video because it wasn’t in hamburger units. Good vid tho
Don't worry it's you know physics and shit, you don't want to get too deep into it or your hair might turn white better stay away
this 3 minute video about opening a coke taught me more about physics than 5 years of school
Cool I never thought that just increasing the length could do so much it was a little hard to understand but cool you should try out more things using this bottle opener
Great feedback, yeah I understand that might be the case depending on people's background, hoping people will skip through the analysis if they aren't able to follow along.
I think the concept is torque. The longer the lever arm the more the savings. That's why manual car jacks have long handles. You don't have to be strong enough to lift a car to lift a car.
Who was it that said, "With a long enough lever and a fulcrum on which to place it, I can move the world" ?
@@hadensnodgrass3472 I believe that was Archimedes
Yep Torque = Fxd = Fdsin(theta) which is what he meant by force applied has to be perpendicular to the bottle opener length.
"I first glued five together to see how the bottle would handle it and sure enough the glue wasn't dry"
The narration delivering it with no surprise at all is just fantastic, going directly into the full experiment as if it went perfectly
The term is "lackadaisically" I just learnt the word from a comment on a random yt shorts a couple of days ago.. and I felt like sharing the knowledge ❤
I saw it more as, "This result was expected. As mentioned earlier, I am a lazy human."
reminds me of the tone of Casually Explained videos
Your videos truly make my jaw drop, I want to learn and know what you know one day, keep up the great work you are awesome!
I came from the shorts. I wish more people linked the part 2 in the comments. You’re amazing.
Thank you for including calculations and whatnot. It was very nice to see a physics problem I would solve in class in a video format.
Love watching these videos that simply explain things like this that I think about in every day life. And I know you’ve been in my area off a bus sign in one of your shorts haha
From the shorts im dropping a follow and like, (cuz its a good video) and cuz you get straight to the point. Looking forward to future vids :)
Just for adding the links you’re now my new favorite CZcams shorts uploader
Thank you so much, I always suck at math in school, but now you’ve been intrigued me enough to want to learn it
You deserve a nobel peace prize for adding links WITH TIMESTAMPS to the comments
I enjoyed this hope ya make more in the future
bro that is how you link to a full video from a short...excellent work, good shit.
Yee
i watched the full video entirely because you were generous enough to give a link to just the result.
Fun little practical demonstration. Kinda reminds me of early Mythbusters and their balloon experiments.
Awesome that you even included a link that is just the result for my easily bored adhd brain. Thank you for that!
0:42 that darn fake eagle follows me everywhere i go, bald eagles real cawing is far less majestic, i encourage you to look it up cause its fascinating how different the sound is
assuming you dont already know all this which you may do lol
why do you hate red-tailed hawks
Oh god, thanks for putting a direct link to the results.
I'm surprised your final calculation wasn't thrown off by the fact that some of the torque is going to bend the bottle openers instead.
This is awesome I want to see more stuff like this online
It needs to be LONGER!!
I swear, I learned more about physics in this video alone, than in an entire year of physics class at my high school
Posting a link to the results timestamp: you are a true hero!
I’m so glad I took 3 minutes out of my day for this
Thanks for the (just results) link didn’t know you could do that 👍
This is an excellent Statics Course exercise! "How many bottle openers [of x length] are requited to produce a moment of force about the bottle cap when it is secured with y force"
(just make it all in EEU or metric please 😂)
This man teaches and makes me understand things faster than my Ap Physics teacher ever did 😂
Great video tho!
Leave it in a very still room and let it collect dust until it's able to open
freedom units were acknowledged, I feel like that's good enough!
Also beautifully made video, when I learnt about this I still thought physics were easy :')
Theory can only take you so far
(Nice video btw)
As a person who was never taught basic algebra before being dropped in an algebra one class this vid is nice
Title should be "how to open a bottle with a banana."
Monty Python would be pround. :D
Thanks for also giving results
The bottle opener tried its best but the banana stole the show lol
The only short that tempted me to go watch an actual full length video.|
Great job dude.
I'm taking statics in the summer right now as an Mech Engineer major, and i makes me happy I understood this. Dynamics and Thermo are next. Then mechanics of Materials 💀
friend:"you got a bottle opener?"
me: "yeah just let the glue dry, and dont eat the last banana"
Legend for the time stamps, got a like and a sun for it
Definitely would love to see more!
I watched the results then got curious and then watched the analysis
nice short and nice vid, went for results, watched the whole vid because it already was pretty short for my standarts.
Never seen anyone using an opener like this pushing from the top down. I’ve always pulled upwards, seemed a lot easier
Yeah that way requires even less force. Maybe he did it like this just because the apparatus is easier to set up
You'd have to hang it over the edge of the table if you did it like normal because the bottle opener would go lower than the surface of the table.
Uh I work at a bar and it's much quicker to push from the top down. Pulling from the bottom is a weird movement, you have to sort of put the bottle through the hole in the opener first. That extra half a second is precious. I only pull from the bottom with tiny keychain openers.
Pushing down is way easier than pulling up btw, requires more force because gravity pulls down.
@@Altrop shouldn’t you pull up to have your arm in position to move on better, rather than your arm going down and then you have to lift it back up again. Those 0.5 seconds add up.
@@sylasviper715the time it takes to position it initially is longer
Thank God you combined newtons (kg*m/s^2) and inches. Love it 😂
Some good comedy moments in here. “The glue wasn’t dry.”
I love you for doing shorts so well
Now you have bottle opener that requires about 1 banana of force to operate!
A surprisingly good video explaining the mathematics of force, leverage and the mechanics behind it. Topped with an excellent use of a Banana!
this is unironically an extremely good explanation of moment if inertia
So you're telling me i need to buy a comically long bottle opener? I'm down where's the merch
Newton inches makes me cringe just like using the bottle opener the wrong way but in this case its the only way to make it work
I only saw the results but as soon as I saw what you were doing I was taken back to all my intro engineering classes😭😭😭
i know this is a really random thing to comment, but i love how just. to the point this video was.
“could we do thing? i dunno, let’s find out.”
explains the general things needed to grasp the concept.
does thing
profit.

Ah yes, thats the content i subscribed for
“Give me a lever long enough, and I can move the world.”
-Archimedes
now this is a youtube short done right
If you made the bottle opener longer could you make one that opens the bottle just through gravity alone?
Teacher: Learn this
JaDropping: When Will I Ever use this?
Teacher: Here
Pretty clever using timestamped links to your videos, I’m surprised I haven’t seen other CZcamsrs do that
Thats how we used to calculate shear force and bending moment in civil engineering.
I love how he even says Newtonmeter once :D
Congrats on hitting 1 million subs
This makes so much more fucken sense then my statistics class…
It would be cool to see enough openers glued together so that their weight alone would be enough to open a bottle
My only problem with the math that I have is that the angle that the banana makes with the lever changes with time. To be more precise, you should add some Calculus to this. :)
You take care of my time, I take care of youe channel❤ new sub!
It’s kind of interesting to see that this could’ve totaly been in one of my exams lmao it’s exactly what I studied
Nice demonstration of torque, but why didnt you weld the pieces together or glue a long rod with much (glue-)contact area on a single opener instead?
2:23 (actual results)
Lol he said Newtonmeters at 1:31
Lol nooooo, force of habit I guess
@@JaDroppingScience lol
@@JaDroppingSciencehuman error?
So basically you need 0 bananas to open a bottle.
thank you for not making everyone watch a 28 min video to see the results
7 inches was very respectable, 30.5 inches is just showing off 😂
You telling me, with enough bottle openers, I could let the wind open my bottle
The Newton inch is such a British measurement.
I like how he could juat get a plate metal that would distrubute the weight evenly and has no risk of breaking but instead he glued real bottle openers to create the ultimate bottle opener.
Absolute madlad
this is the peak of 2023 youtube, glad I've been here and witnessed it firsthand, next time please use some other _usual_ unit.. cba with bear stomp per eaglebeak squared
Great video!
Give me a lever heavy enough and it shall move the world. - Archimedes
She: he's probably cheating on me!
Me:
Damn thing opened itself
Saw the short, had to see the vid now im subbed
When you use a breaker bar to open a bottle for maximum overkill!
Did I just watched a guy that physicly explains how to open a bottle of coke with a opener? Thats brilliant
Seeing Newton inches made me discover emotions I never knew I had
“Newton inches”
so you have chosen… death
Ah lee-vers. The ultimate physics exploit.
