This catapult shot a 0,5 gram projectile 16 meters. Making abstract art by throwing paint with a magnetic catapult. This seems to be the most efficient catapult design I have made so far. The magnetic trebuchet shot max 14,5 m range without the sling attachment and it was a far more complicated build with more magnets. This is a pretty straight forward build. The slow motions were 120 fps / 640 x 480 px
Only needs 2 sets!
