1. Levitation by Pringles Can
Supplies:
Pringles cans with lids
Nail
Paper clip
Magnet
Procedure:
Poke nail through can an inch from the bottom, perpendicular from the view through the window.
Cut string to the length of the can.
Tie one end around the nail in the can and the other end around the paper clip.
Put lid on can and then magnet on top.
Pull the paper clip up until the magnet starts attracting it.
What’s Happening:
The force of the magnet is working against the force of gravity to hold the paper clip up.
Notes:
By varying the length of the string, you can see the distance dependence of the magnetic force.
The farther away, the less force.
