How long should a mousetrap car string be?
The length of the string is about 25″. Therefore the string can be wrapped around the dowel 25/0.785 = About 31.8 times. So the minimum distance travelled will be the number of times the string can wrap around the dowel multiplied by the circumference of the wheels, which is 31.8 x 14.92 = 474.456″, or about 39.5ft!

How do you make a mousetrap car go forward and backwards?
