Flying Saucer

Project Number: 11

Parts Needed For Circuit: All The Parts Used From Project #2, Polarity Reversed On M1

OBJECTIVE: To make a circuit that launches the fan blade to simulate a flying saucer.

Description: Rebuild the circuit from Project #2, but reverse the polarity on the motor (M1) so the negative (-) goes to the positive (+) on the battery (B1). New alkaline batteries are recommended for this project. When you close the slide switch (S1) the motor will slowly increase in speed. When the motor has reached maximum rotation, turn the slide switch off. The fan blade should rise and float through the air like a flying saucer. Be careful not to look directly down on the fan blade when it is spinning. The air is being blown down through the blade and the motor rotation locks the fan on the shaft. When the motor is turned off, the blade unlocks from the shaft and is free to act like a propeller and fly through the air. If the speed of the rotation is too slow, the fan will remain on the motor shaft because it does not have enough lift to propel it. The motor will spin faster when both batteries are new. If the fan doesn't fly off, then turn the switch on and off rapidly when it is at full speed.
