Easily make a body of a windmill with a hexagon and polygons extending down from the sides of the hexagon. Use a sharp object to make a hole in the middle of the cross section of the fan. Use a motor, battery (in a battery holder), switch and wires to connect them all together. The order does not matter.
Insert a wooden skewer through the straw so it can rotate freely. Towards the end of the straw, tape one end of a piece of string to the straw. Tie or tape the other end of the string to a paperclip. Hold the ends of the wooden skewer and blow on the sails of your windmill model.
