Rubber band powered car?

Question

I have to make a rubber band powered car for science. I have no idea whatsoever! I don't even see how a car can be powered by a rubber band! Can you tell me how to make one and how it works?!
Thank you.

It's easy - you make a frame, and you put an axle in the front, and axle in the back, and attach the wheels. Put a crossbar in just behind the front axle with a hook in the middle, and a attack a small catch to the middle of the rear axle. loop the rubber band around the hook on the crossbar, and hook it on the catch of the rear axle. Turn the back wheels backwards tightening the rubber band until it can stretch no more, then set it on the ground and let it loose

Answer 2

so you either need a car powered by the elasticity of the rubber band, probably by stretching and twisting it. Do you have any guidelines for the dimensions of the car or the type of rubber-band. I used to buy them for like a buck at the store. You first need to make your axles and wheels.

Answer 3

have you ever seen a ruber band powered airplane... do the same thing... just make the propeller into weeles

Answer 4

Most importantly, you'll need a way to regulate the power. Maybe a transmission from a toy electric car.You'll also need a way to wind it up without losing the existing windings. Wheels and frame can be copied straight out of any remote controlled toy car. In fact, if you replace the electric motor with the rubber one, you could just do a straight conversion, giving you an R/C rubber band car!

Answer 5

Hi. Can you use the rubber band as a catapult? It'll be the fastest car, for sure.

Answer 6

I used to make "spool tanks" when I was in middle school. All you need is a thread spool, a pencil, a rubber band, cardboard, wax (or soap), and a thumb tack.
