Show your kids the phenomenon of "afterimage" with this DIY little machine. All you need is:
- some iron or copper wire
- a straw
- a sheet or white thin cardboard
- colors
I took the idea of the turbine from a kids craft blog, and I really would like to thank the author but I can't find it back. I feel sorry for that... I added the colors disk to have a purpose for the movement.
