Does anyone have any ideas for this project? I need a mouse trap car that will move in a circle and shoot a projectile to hit a target. I was thinking of having 2 mouse traps, one connected to the front wheel and one connected to the back wheel using the usual set up to move. And to go in a circle, I would adjust the front wheels. Then on one of the mouse traps, attach it to another string that is connected to another mousetrap that will be set off once the first mouse trap reaches a certain position.
