Thanks,

Does that mean you could set your vehicle upright like its doing a wheelie, and make your vehicle infinitely long? Or do all 4 wheels have to be touching the ground?

Most designs that I have seen include an added length of material to the "jaw/hammer" that extends the distance traveled in order to apply the force to the axle more effectively than with the regular jaw/hammer. Does this rule mean that we cannot extend more than 1 cm beyond the base, or does it mean that the original jaw/hammer cannot extend more than 1cm beyond the base? Thanks in advance.

Alright. So the rules state that the jaw/hammer must not extend 1 cm longer than the wooden base of the mousetrap. The metal Jaw/hammer cannot be modified (like bending, cutting, melting, etc.) to achieve better mechanical advantage. However, yes, people have added a drive arm to the jaw/hammer. Hopefully that helps. Good luck!

Why is this 1cm jaw/hammer even a rule? Are there mousetraps where the metal snapper (aka jaw) does not snap down completely on the wood base? I wouldnt think for an optimal mouse stike, there would need to be a solid surface under the jaw, not one that sticks out past the base.

This has been seen at tournaments before.
