OK, I can't decide what is the best practical idea to further enhance my sewage twister prototype. I will test every one of these three suggestions, but only one of them can win the Rambone... so please vote! The ideas are all presented in this thread: https://www.theslingshotforum.com/f1...ot-ideas-thread-31742/index18.html#post247525 Number 1 is Nyam Nyam's idea to use a brightly painted and marked ball that can be seen rotation in flight in the slomo. Post #13. Number 2 is Nerd herd's idea to use four bands instead of two, arranged in an "X"-shape, so the tube is more evenly stressed. Post #21 Number 3 is Mr. Piejean's simple, but brilliant idea to ADDITIONALLY twist the bands for more rotation. Post #26. Which one is the coolest idea? Deadline is Christmas eve, midnight, GMT+1 (Berlin, Paris time).
