Screw

[thesaga]

Hi! My friend is doing Mission Possible and he was struggling with the Archimedes screw and how to turn it. I, because I do helicopter, suggested that he use a pre-winded rubber band and a mechanism to unwind it, making the screw spin like a helicopter rotor. However, I think this will be unreliable. If anyone is willing to share what they did, I would greatly appreciate it.

Hello I also did the Mission Possible division B, and to power the screw I used a rubber band perfectly perpendicular to the screw and then made a release with a marble rolling over a mouse trap and activating it
