Caleb51 Posted April 1, 2006 Share Posted April 1, 2006 Hello all! I thought I'd start a thread on anything that spins, flys (Not like rockets, but flys by spinning) and jumps. Does anyone know the formula for something like a jumping jack, or those things with wings that spin so fast they fly like 40 feet? Link to comment Share on other sites More sharing options...
Von Bass` Posted April 2, 2006 Share Posted April 2, 2006 I am not sure about this, having never made them, but I believe that jumping jacks were simply a line of compressed gun powder and a line of loose gunpowder, one that provided the thrust, or jump, and the other that provided the bang. When made in a zigzag fashion, this burnt through its length. Correct me if im wrong! Link to comment Share on other sites More sharing options...
Caleb51 Posted April 2, 2006 Author Share Posted April 2, 2006 I've never used one with a bang, so I may be wrong, but I think that is incorrect. Someone who knows for sure? Link to comment Share on other sites More sharing options...
