Should a mousetrap car be heavy or light?
Lighter mousetrap vehicles will require less energy at the start and can use longer lever arms for more pulling distance. Always use lightweight components when building a mousetrap vehicle. bonus tip: lightweight mousetrap vehicles require less pulling force off the start.

What kind of string is best for a mousetrap car?
The string has to be strong enough to handle the pulling force but flexible and thin enough to wind tightly around the drive axle. We recommend using a Kevlar based fishing line because its high strength. You should stay away from nylon fishing line and dental floss, these do not work well with mousetrap racers.

What makes a mousetrap car work?
A mousetrap car works on the principle of a lever. One end of the lever is connected to a spring. When a force is used to pull up the other end of the lever up, the spring tightens, storing energy. When the lever is released, the stored energy in the spring is transferred back to the lever, and the end snaps back.

Are 3 or 4 wheels better for mousetrap cars?
So what is better, three wheels or four wheels? The answer depends on the contest, if we are to build a super fast accelerating speed-trap racer then over coming rotational inertia is one of the main objectives therefor three wheels will always do better than four wheels when it comes to performance.
