There are few toys which are as exciting as this Magnetic Air Fan. You will need a plastic bottle, a cycle spoke and two ring roller magnets. Stick two colored on the bottle at a distance of 10-cm from its lid. Cut the bottle and then cut a dozen petals. Open out the petals and then flatten them. Then twist each petal into curved blades. Make a hole in the bottle lid and press-fit a cycle spoke nut in it. Tighten the cycle spoke in the lid. 
You will need strong ring-roller magnets which stick to a steel container and also roll on them. Place two roller magnets on the on the spoke. Now place the Fan with the magnets on the can. When you place the toy under a ceiling fan the Bottle Fan will rotate and the whole toy will go round-and-round the container.
You can even keep the Bottle Fan outside the container and it will glorious go around in circles captivating everyone.
