A Mini-Crown for a Micro Rocket

Caption

This is L. Brad King's prototype of a ferrofluid ion thruster. When subjected to voltage, the points of the crown rise from a ring-shaped trench circling a one-inch block of aluminum. Ions shooting from the points create enough thrust to power a micro rocket.
