Quarter shrinking is somewhat related to tesla coils.
The major difference is that there is no need for for a secondary coil, and
the primary is kept small. The capacitor is also only chaged up once to
prevent it from discharging into the transformer. When the capacitor is
fired, a surge of voltage produces a magnetic field strong enough compress
the coin whithin the coil. The resulting force (Newtons Third Law),
however, rips the coil apart and hurls the pieces at bullet speeds.
