Read about the Quarter Shrinker

Read about the Quarter Shrinker at Bert Hickman’s experiments page. The pictures alone are worth the trip. “The quarter shrinker uses a high voltage capacitor bank and a triggered spark gap to apply up to 125,000 amps through a small work-coil of #10 AWG magnet wire which surrounds the coin. Once the spark gap is triggered, a current of over 1 million amperes in induced into the coin, and the interaction of the induced magnetic field and the field from the coil cause the coin to shrink radially-inward. At the same time, the work coil explodes into copper shrapnel, and then into a 8″ ball of plasma. This all occurs in about 20 millionths of a second.”
