  • All that work and you couldn't be bothered to do enough work to put a (period accurate!) sling on the thing. You coulda been throwing a lot farther.

  • You should shoot water balloons at the cheerleaders.... revenge of the nerds!

  • @blackittysamurai we actually did try to shoot water balloons, but unfortunately the G forces are too high and the balloons explode during release. Perhaps if we looked into buying more durable balloons it would have worked.... but we were a bunch of poor high school kids lol

  • @AlphaGinger113  Wow, I never thought of that, I wonder if condoms would work, being designed to bear higher stress loads, not to mention being extra icky for those stuck up cheerleaders.

  • I kept thinking "For the love of, don't put your head above it!" D:

  • @Aragashia If only you knew the injuries and accidents involved in the making of this catapult. When we first tested it with maximun torsion and more elastic bands it managed to flip itself over and destroyed my garage.

  • What were the dimensions? L x W of base and the H of the arm and the length of the launching arm?

  • @Wargamer008 if I remember correctly the length of the base was ~ 8 feet length, 4 feet in width, and the arm height was just over 9 feet

  • @AlphaGinger113

    Thanks. What was the total cost of this project? I am making my catapult for AP Physics and yours looked like the perfect one to model after.

  • @Wargamer008 Its hard to pin down an exact cost because we had to go through quite a bit of trial and end and we ended up breaking things or switches stuff out. If i were to estimate i would say about ~$300 if you did it right the first time. If you buy a pre-made winch/crank and buy low quality rope it would be cheaper though.

  • I luv it. It is my science project :D

  • @thepidgeonification Sure thing!

  • haha im making a 10inch catapult in my algebra 2 class thats exactly like that, but i cant get the crank right

  • @purplelamprox haha ya the crank is a pain to deal with. One problem we keep running into was that we couldnt mount our crank in a "sturdy" Location and the throwing arm kept ripping it off.

  • that was so cool

  • well sorry I didn't see the rope at the bottom of the machine

  • that is the moment all studies are used

  • thats not tosion

  • @ACDC5968 Wow really?... Sorry to piss on your campfire but it is in fact torsion, the latex tubing was used as a boost. And that is why I labeled this video as Giant Hybrid Torsion Catapult

  • @AlphaGinger113 yeah thats torsion, the tubing helps acceleration.

  • nice catapult, what'd you use for the torsion?

  • @ben38619 We used about 150ft of 1/2in. military grade nylon rope. We werent able to torsion it as much as we would have liked though because we didnt make our frame thick enough.
