If yes then I would llike to try sewing thread(any stiff threads) fishing line and any other stretchy type of string.

On the wiki, it says to add a bar to the trap. But, isn't that modifying it and thus breaking the rules?
For the third example on the wiki, it says to wind the string x times around the axle to travel x meters. Does this assume that the circumference of the circles is 1 m, or is the ratio of winds to wheel turns not 1 to 1 because of some other factor?
