    By Monday? You'd better get cracking.

    Best guess is use 2 mousetraps... Fire them off one at a time.

    Why not have one wind a rubber band or something... you will have to adjust the tension but have it wind up then it should be able to get back..

    Tie the car to a string suspended from the ceiling?

    Fix the mouse-trap FIRMLY to a little car. Fix the trap in a position such that when the wire thing comes to a stop, the momentum of anything attached to it will be in the direction the car will travel. Attach a weight to the end of that wire part. Put a spring on the front of the car. Put a firm support behind the car, so it can't jump backwards. Place a hard surface in front of the car, 3 meters away...
