You could use the twine used for kite strings. I've got a ballista (a twin-spring torsion engine) that uses that stuff. It works pretty well.

have you seen how many other videos and slideshows there are on here? this site is also about showing off what you made or showing how you made it as well as constuctive critisism, so i suggest if you are going to putdown other people's hard work, do it on another site

I love to make and build things, especially duct tape things, catapults and secret stashes. I can do a little work with electronics, and I am a slight pyrotechnic as well.
