Mouse Trap Science Project

My daughter's Freshman High School project: Build a vehicle that will travel at least 20 feet / 6 meters in a straight line.

She found some designs online that utilize a mousetrap as a power source. We used old 33 RPM audio records for wheels. The mousetrap bar pulls some fishing line that's wrapped around an axle to drive the wheels.

My "it did it again" comment was regarding a recurring problem of the fishing line not releasing from the axle and thus hanging up the car.

With the project due tomorrow we decided to not make any more improvements to it. This run was about 83 feet / 25 meters so we knew it was already an easy "A" for her. The testing was done with permission at a rural hospital's corridor.
