Push the press switch (S2) until the motor reaches full speed, then release
it. The fan blade should rise and oat through the air like a ying saucer. Be
careful not to look directly down on fan blade when it is spinning.
If the fan doesn’t y off, then press the switch several times rapidly when it is
at full speed. The motor spins faster when the batteries are new.
The glow fan will glow in the dark. It will glow best after absorbing sunlight
for a while. The glow fan is made of plastic, so be careful not to let it get hot
enough to melt. The glow looks best in a dimly lit room.

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 as a propeller and y
through the air. If speed of rotation is too slow, the
fan will remain on the motor shaft because it does
not have enough lift to propel it.
