MEET THE BIT
Use the fan to create a gentle breeze, perfect for cooling
things off. You can also try taping small things (like stickers
or pieces of paper) to the center of the fan for some
spinning visuals.
MINI-CHALLENGE
Can you invent something that uses the fan to move an
object across the table?

HOW IT WORKS
Inside the fan is a tiny motor.
When it receives a signal,
it spins. The more signal it
receives, the faster it spins.
