Take the next giant leap to about friction, power, and design with KELVIN©'s new generation of “Build a Better" Mousetrap Vehicles".
This giant double mouse trap racer has  ball-bearings for even less friction. Examine how far or fast it goes. Test the acceleration and compare results with the single mouse trap racer. Developed as an open ended design activity, students create their own body design, experiment with the position of the traps and the length of the lever arm.
Minor soldering is required.
