Mouse Trap car

Step 10Rear axle

Rear axle
Push the pen with the string into the back eyelets. Pull the string through the eyelets so that it's between them (or slide through the gap if you had to widen them). Tie the string to the tip of the flap that will move as the trap springs. Those more ambitious might want to brace it with something between the spring and the back to make sure it doesn't snag or fray, but I didn't bother, which does mean the string gets tangled or frays every so often.

When you set off the trap, how do you get the string to not stop the axel from spinning?

 Larry, where do you put the string after, you haven't really given clear instructions on what to do with the string part.

WHAT ABOUT PLASTIC STRING WOULD THAT WORK...BECAUSE THATS THE ONLY STRING I HAVE RIGHT NOW SO WOULD THAT BE GOOD TO USE..OR SHOULD I TRY SOMETHING ELSE

i used weed eater string and melted the tips, would that work?
Dec 30, 2008. 6:52 PMan1sh says:
it would work, but, longer a string, the more distance it would cover, try finding a string that sticks like rubber against a plastic causing traction i used a melted rubber and made a long single rubber band
