Hi, I made my mousetrap car with wood.
It looks like up side down Y shape. And there is a hole (penny size) at the close end of each wood.
I used blank cd as tires and the screw to hold that.
And I used the rod (less than penny size) that looks like cylinder connect the tires with screw.
The problem is the string. I used shoe lays and needle string but they don't work.
The weight is about 64 FL OZ bottle size.
I need help with the string.
Can any one tells me what kind of strings do I have to use for my car?
