Spoiler: The lamp explodes.
A blown 12 volt halogen lamp from a car headlight was put on the output of the resonant MOT power supply. Although the filament was previously broken, the high voltage easily jumps the spark gap left by the blown filament. The super-hot electric arc melts the side of the glass, causing an impressive (and quite loud) implosion/explosion as the high vacuum is released and the filament oxidises. The remains of the filament then burns in the air just as the circuit breaker trips. A bubble can be seen forming in the melting glass prior to failure. Luckily the rest of the glass did not shatter, so no mess or broken glass was produced.
