Induction Motor	Eddy currents set up in a floating metal ball repel the magnetic field from the apparatus and make the ball spin.	Real	Real MPG	E and M 5H20.50
Inelastic Collisions, equal mass	In all cases, the two carts stuck together after the collision will have a momentum that is equal to the combined momentum of the two carts before the collision.	Real	Real MPG	Mechanics 1N30.30
Inelastic Collisions, B/s mass	In all cases, the two carts stuck together after the collision will have a momentum that is equal to the combined momentum of the two carts before the collision.	Real	Real MPG	Mechanics 1N30.30
Inelastic Collisions, s/B mass	In all cases, the two carts stuck together after the collision will have a momentum that is equal to the combined momentum of the two carts before the collision.	Real	Real MPG	Mechanics 1N30.30
Inertia Rods	These rods weigh the same, but due to the distribution of the mass, one is harder to rotate than the other.	Real	Real MPG	Mechanics 1Q10.10
Inverted Liquid	An index card is placed on top cylinder full of water. The cylinder is then inverted. A slight vacuum is created, keeping the index card sealed to the cylinder, thus keeping the water from pouring out.	Real	Real MPG	Fluid Mechanics 2B30.45

Jumping Ring; cold ring, regular core	The magnetic field induced in the ring opposes the magnetic field of the core, making it jump off the apparatus. Cooling the ring before hand in LN2 lowers its resistance and allows it to jump higher.	Real	Real MPG	E and M 5K20.30
Jumping Ring; cold ring, long core	The magnetic field induced in the ring opposes the magnetic field of the core, making it hover above the apparatus. Cooling the ring before hand in LN2 lowers its resistance and allows it to hover higher.	Real	Real MPG	E and M 5K20.30
Jumping Ring; split ring, regular core	A magnetic field cannot be induced in the ring when the ring is split, such as seen here using an aluminum Pepsi can.	Real	Real MPG	E and M 5K20.30
