 P: 1 I need to build a mouse-trap car that goes forward 3 meters and goes backwards 3 meters by Monday... is that even possible? Pls, help me with ideas...
 PF Patron Sci Advisor Emeritus P: 1,819 By Monday? You'd better get cracking. Best guess is use 2 mousetraps... Fire them off one at a time.
 P: 1,109 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..

## How do you get a mouse trap car to go forward and then backward?

my suggestion is to find a mousetrap car online and mondifty it with the wind up sequence

here is a site claming to have links to good directions on straight foward car

 P: 1,109 here is some students who created a mousetrap car that went forward and backward with 2 traps like enigma said http://www.andrew.cmu.edu/user/ejl/?M=D
 P: 1,109 Another two trap foward/backward design http://www.andrew.cmu.edu/user/alaue...gn/mouse2.html
 HW Helper Sci Advisor P: 1,572 Tie the car to a string suspended from the ceiling?
 P: 183 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...
