balloon popping machine

Last Friday i made a new rube goldberg track, it was my second. It was a balloon popping machine it took 3 tries here are the steps.

For the machine I threw a ball into a line of books kind of like a domino track the books hit each other into the balloon that hit a knife that I used sticky tape to attach to a tissue box and the balloon popped.

In the end I had lots of fun making the track.
