Question

How will you make levitating propeller?

Answer 1

1. Make a propeller from a 500-ml plastic bottle. Make a hole in the bottle lid.
2. Screw the lid with the hole on a bottle half-filled with sand. Press-fit a stiff straw in the lid. Embed the straw in the sand to make it stand erect. Place a few ring magnets in the straw. Similar poles will repel each other.
3. Place two magnets each inside and outside the propellor lid. These magnets will automatically stick to each other.
4. Like poles repel and this levitates the bottle fan. The ceiling fan makes it a spin.
5. Place the propeller on the stiff straw. The magnets in the straw and the propeller should repel each other. This will make the propeller levitate. On placing it under a ceiling fan the propeller will spin very fast.
