String is often one of the most over looked components when building a mousetrap powered or rubber band powered vehicle. The "right" string makes a a huge performance difference of any mousetrap powered or rubber band powered vehicle. Spider Wire is an advanced string that is made from Kevlar fibers for incredible strength and performance. One roll contains 150 yds. of string, more than enough for any large group activity. The "thinner" the string, the better it winds around a drive axle and the better the performance. The problem with most strings is that they are to thick and/or they do not wind evenly on the drive axle causing inconsistent performance and even poor performance. Thread does not hold up to the continued stress and large forces and normal breaks. Spider wire is the only string Doc Fizzix ever uses for building mousetrap powered and rubber band powered vehicles. Spider Wire is a fishing line that is made from kevlar fibers for incredible strength and performance. Spider Wire will not stretch or break.
