The Spark Gap Blew Up

This WAS the brilliant Asynchronous Rotary Spark Gap that we made a few days ago.

Unfortunately there was an incident. But someone (Not naming any names) decided it would be funny to ramp up the Variac from 20% power to 40% despite the warning I gave that the plastic was starting to warp from the centripetal force. The plastic disk then "gave up"and shattered into a million fragments sending sharp shards and 8 heavy duty bolts across the room at an incredibly high velocity!

Needless to say a new disk will be made. Here are a few pictures of the offending article shortly after the incident.
