The materials you will need are:
1. 1 battery (any size)
2. Copper wire (how much you will need depends on how big your battery is)
3. 1-2 magnets (they have to be able to conduct electricity)
Step 1: Putting It Together
To start, attach the magnets on the bottom of the battery.
Next, bend the middle of the copper wire so that the middle is a point.
After that, put the point on the top of the battery and bend the 2 ends of the copper wire to touch the magnet/magnets.
Finally, touch the 2 ends of the copper wire to the magnet/magnets and it should spin in a circle!
Extra: you could attach things to the copper wire to make it look more decorative, like a merry-go-round!\
