To make this simple model you need an old plastic bottle, a syringe, a cycle spoke, a ring magnet. Cut the bottle about 15-cm from its lid. Then cut 12-equi spaced petals on it. Decorate them with tape. Then press and flatten the petals. Then twist each petal to transform it into a curved blade. Press-fit the bicycle spoke nut in the bottle lid and then screw on the spoke to it. Sharpen the end of the spoke to a point. Pull out the plunger from the syringe and remove its rubber piston. Stick the rubber piston with adhesive to a ring magnet. Push the cavity of the rubber piston in the syringe end. Stand the syringe vertically and then place the pointed end of the spoke in the rubber piston. 
Now place the whole assembly under a ceiling fan. The toy fan will rotate very smoothly. Because of the magnet you can also stick this toy outside to any steel object.
