Nice work, boys! Keep it up! #GoPro

cool idea... now phase 2, make it whistle and the deploy a parachute at max altitude. ;~D

Somebody I know built a T-shirt cannon exactly like this for a science club project. He had big problems with the tank and the valve leaking air. I see you've solved those problems quite nicely. This is the best one I've seen. Great job!

Your barrel is not smooth , therefore it will never land in the same place as before because it is unpredictable , you guys should print out a rifled barrel and it will shoot faster and more accurate.Well done guys! :)

Great! This was fun... I have a project coming up involving an air cannon as well... :)

Loved it! And yes, please give us more geekery and applied science. And Fun!

Soooo cool! I loved the waltz :) Good job on the product development, looks awesome!

This is so cool I love this so much keep it up can't wait for more 😉

Wow can't believe this is your first video, awesome content already.

I love the fins!

That was aaaawsssoommeee!

you guys are awesome and so creative

Supreme athletic abilities like real engineers.

Awesome. I have a WWII helmet too. Oh, and nice catch!

love this channel

well now I know I can launch my gopro hero4 session from a cannon and it wont break haha

been here since the beginning, and can't wait to see what is to come!

y'all are going places

That was sick

Great video and channel. Grettings from Argentina!

You guys deserve way more subs

Great job guys! keep up the good work! greetings from italy!

WELL DONE , THOSE MEN !

Gizmodo brought me here, Awesome video!

these people are amazing

I was here before 1 mil subs. proud to say that.

Coolio guys keep on going, Good luck.

AWESOME

ooooooor you can put a gopro on a quadopter drone ! hahaha that was fun to see the world moving this way

now that was cool. Can't wait till you guy's make a stable version and try to launch higher. :D

when I saw the headline my first thought was more money than brains. clearly it's a toss up. well done gentlemen!

why do you guys only have 23.013 subs??? you deserve at least a mil

Nice cannon. You could use it for baseball practicing catching pop flies.

Great videos so far guys. Looking forward to more. My only suggestion is to normalize your sound volume. At times your dialog got quiet.

que buen video chicos buen trabajo

holy hell, if only there was raw footage without the music, that whirring sound is amazing.

Nicely done! And thanks for the MM love! ;)

cool stuff

this is cool

i think this has potential

Protip: If you don't have access to a 3D printer to create the projectile, tennis ball canisters will fit perfectly inside the PVC barrel.

Maths are different with air and that projectile shape Also nice litter

Does one of you play paintball? A set of Flex's is a pretty nice mask to just have kicking around haha

Wow..that was cool!! :)

I'd be interested to see that footage with some heavy image stabilization

yalls is crazy smart

They should strap a Superman action figure on it and have a GoPro that would be really cool too! It also would be cool if they have his arms move when the thing would spiral

Super legal e divertido, parabéns!

did you factor the speed of wind into the projectile motion equation

I know the song in this video might be available under who-knows-what kind of dubious license agreement, but all I can think of is DigitalRevTV now since I heard that background song first over that channel.

Pls make a video of How you Guys made that canon

thrilling shots :)

What voltage do you apply to the valve? Can it work on 12Vdc, or is it 24vdc ?

Great!! Very fun... ;)

you 2 deserve more subs!

nice!

Haha fun!!

Now attach a parachute that opens when its falling so the camera films the ground (cheap drone?)

A flamethrower that actually shoots out air and the air can even blow a person off his/her feet

can you do a vid on your cannon

nice video

U guys live in Oakland ?

Why did the camera spin?

they should create this helicopter projectile thing they can shot out the cannon to reduce the impact to the ground and also make a nice Birdseye view

To reduce the spinning, would adding some weight in the bottom side of the camera housing help? Maybe then if shot from a 45 degree angle the spinning in the flght path could be minimized. Naaahh nevermind bad idea. It will still spin around...

NEEEEEERDS! (I mean that in a good way)

nice

With a few modifications, you can make a potato gun. Instead of air, you can use hair spray (the chamber would probably have to be a lot smaller) and add a piezo-electric trigger.

How did the fins deploy? Spring loaded it aerodynamic effects?

Hi David and Ryan! Here's an idea: 3D print the projectile with glow in the dark filament and instead of a GoPro you could fill the space with a 0 G trigger mechanism that shoots several flashes embedded around the projectile. If you film it at night with long exposure camera setting, it would be an awesome way to actually see how different shooting angles change the trajectory of the projectiles as well as its maximum height. :D

nice canon bro #gopro

Surely the equations ignored air resistance?

Good job guys! (don't quit your day jobs just yet though)

3:26 omg, he almost destroys his race laws

Nice. Should have gone with 60fps though.

Fucking Amazing

the air cannon is easy... I want to your print data for the camera shell..

Very Neat - Wish You could Tweak the Fins , so it wouldn't Spin or Spin very slowly .. Still 2 Thumbs Up ! Especially the Catch & Musical Timing . . . Ha Haa Nice . .

Can you guys go more into depth on the mathematics at 1:21?

Can you provide the 3d printer files?

Is the sound while the GoPro is going though the air real or fx?

parachute in tge projectile would have been more cool

very cool the camera needs a para shoot lol

3:47, play at 0:25x

Hola

I only kinda miss the whole movie from the caught attempt, feels like you cut the most important part!

Such important work for mankind. Your ability to use the bicycle pump and shoot that into the air is almost at genius level. Most parents brag their children became doctors, lawyers, surgeons or ceo's of great companies. Your parents can brag that you've discoved a way to shoot something in the air and then catch it. Sort of like your grandparents did with small plastic army men and parachutes when they were kids. Your success rates you right up there with: elected officials, telemarketing, use car salesmen or even becoming youtube aficionados with a cult following over 500 likes! Please Please tell me your parents personally funded your education and no tax dollars were used.

That made me feel dizzy

all those complex calculations and you kept missing the spot where it landed exactly?

flux off haha

First video

the goal of the attempts wasn’t clear and the whythis is awesome at the start of the video is non existent

This is your 160th comment on this video

Now fire a metal shell from a military cannon...

Intro

It's a mortar. Stop that spin, or post-process to cancel it out.

Fix your bottom left text, it says "eclectical" engineering. It should say, "Electrical", other than that great video!

eCLECtical Engineering, not eLECtical Engineering. Mark rober sent me
