Strings Wound

How can I make an easy mousetrap car?

I need to make and easy mousetrap car. Can you please help? Thank you so much!

There are lots of design instructions ont he web. A couple of key things to think of if you are in some sort of contest:

Keep the weight low
Use a high a drive ratio as possible
Use as long a lever arm as possible

My son made his by brazing a pice of coathanger onto the trap arm.

Better designs use very light, very large diameter wheels. I've seen excellent results using CD discs. Make sure you get a good axle and center it well.

Make sure the string winds and unwinds cleanly and without obstruction.
