• I did a mousetrap car (circa 1993) that had a 2 LPs for rear wheels and a little plastic front wheel. The body was a "Y" shaped peice of 1/4" foam core. I contructed the axles from small copper tubes with R/C car bearings and 1/8" alluminum axles.

  The point is, you need to store all the energy of the mousetrap in the inertia of the drive train because the mouse trap is designed as a sudden burst of energy. It comes down to the highest mass that the trap can move with the lowest rolling resistance.

  If this is still a graded thing, email me and I'll draw up the winning plans.

• okay, so just out of curiousity, does anyone know that the best way to do this is with only two wheels. Use the axle as the ballance for the trap, and put some sort of weight on the bottom. this is flawless.

• we know how to make this mousetrap car at union city high school and we know how to make it work. you guys are stupid if you can't figure this out. i'm saying that 10th grade honors physical science can figure this stuff out, so stop boo-hooing that this stuff is too hard. suck it up and stop crying.
