How to make Elastic Band Powered Car?

Answer 1

You build a basic car, with a body and a way to support the front wheels and the back wheels.

Each set of wheels should be firmly attached to an axle, maybe a piece of dowel, so

that when the axle turns, so do the wheels.

Then you need some way to

attach the end of a strong rubber band to the middle of each axle so that

when you rotate the wheels, the rubber band winds around the axle and

stretches tight.

You can do this with a small nail or screw put carefully

through the dowel. The best way to wind the wheels is probably to push down

on the car while you push the car along a surface, like carpet.

once the rubber band is really tight,

you let the car go, and the stored energy in the rubber band unwinds the

axle, and off goes the car

You don't have to have the band wind around

both axles ... you could make it either just frontal drive or

rear-wheel drive, but it probably goes better if you use both axles.

You

could also use two rubber bands, one for the front wheels and one for the

back wheels, with the ends of each rubber band fixed to the middle of the

car.

Remember, the car will go fastest and the most distance if you use a

really BIG strong rubber band, and can wind it up around the axles really

really tight. But if you make it TOO tight or too strong, the car or the axles might break when you wind it up, which is not good and really annoying.

Another way of making a car like this is to make it like the rubber-band

powered toy airplanes. Make a light frame with 4 wheels, and buy a little

toy propeller or take it off a toy airplane, then wind up the rubber band

by winding the propeller. Then when you let go the propeller, it will drive

the car along.

Answer 2

You should attach the rubber band to the car twist the rubber band as far as possible then let it go!
