Toypedo

Update 02-Aug-2015:
• Uploaded the smaller 3-blade propeller model seen in the video.
• Tweaked the coinweight models. The coinweight_threads part would sometimes split apart when inserting the coinweight_clamshell part. I beefed up the part that was breaking and left more room for the clamshell to be inserted.


This toy is a rubber band powered, propeller driven, underwater torpedo. Assemble the components, wind up the propeller, and see how far it goes underwater. Designed in re arrangeable sections that change the Toypedo's dynamics, the Toypedo is made for thought-provoking pool-time fun for kids. How far can you make it go?

Things kids can learn:
• How moving weight and buoyancy affects the travel arc. More buoyancy in the front will make it curve upward - and more weight in the back will do the same!
• Newton's third law - When the rubber band twists the propeller-end one direction, it also twists the other end the opposite direction. Easily illustrated by
