Pinwheel is easy to make

See introduction at this link.
You can make them from heavy paper, and more permanent models from heavy tinfoil or lightweight tin. Cut a 5 1/2" square, then cut in diagonally from the corners 2 1/4". Draw around the edge of a nickel at the end of this line and cut the hole out. Then bend in one corner at each diagonal line, run a pin through it and into a stick.
