Tadashi is back with more mathematical toys - this time small tubes which do intriguing things when they spin.

Film by Pete McPartlan (who did the animations) and Brady Haran.
NOTE: Due to the limitations of cameras and YouTube compression, we adjusted some frame rates in editing in an attempt to better show the spinning tubes as they appeared to the naked eye. Still not sure how well we did, so please take Tadashi's word for it when he describes what we see! The best thing to do is make one yourself and just try it... It's actually quite easy.
