Homemade High Voltage Coilgun: When Timeout Is Not Enough

Raising a bright and willful child is not always easy. For the times when a timeout does not convince the little tyke to conform to the plan, a shock from a high voltage coil will often do the trick. And if not? A rubber-tipped metallic projectile fired from this homemade coilgun will almost certainly induce compliance. Particularly if you emphasise that the rubber tip can always be removed. ;-)

Oh, about the unconventional child-rearing practises above? Just kidding. I have always been more of a Montessori custodian myself.
