Racoon Proof Ice Chest
Showing how a layer of aluminum foil is placed under the cooler, with contact to the bottom copper tape.
This placement is just for example. In practice foil is placed in a layer covering an area larger than the cooler serving
as one pole of the energizer. Any racoon who stands on the ground foil and touches the side of the cooler will get a shock.
As they will, if they jump on the top. The energizer charges up (simple induction coil operation)
and discharges 5000 vdc about every second.
