- some iron or copper wire
- a straw
- a sheet or white thin cardboard
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.
Step 1: Get Your Metal Wire
I got mine from a dyer hanger. It has to be solid enough, but easy to cut and bend...
Step 2: Prepare the "blower"
Bend the wire, cut it, and strap the straw along it.
Step 3: Build the Turbine
I'm afraid my grandson did put too much glue when building it, but it's working well though. So I won't complain...
