Create a windmill using 3 water bottle. This windmill base has 3 screw in sockets to put common water bottle in. Screw in the bottle, see which direction it ends up in and cut the bottle to create a wing.
Designed for a 4mm steel rod.
The windmill seems to pick up a small breeze but for now it quickly stops, due to too much friction.
