Blowing up BIG capacitors!

In this video, I have a few capacitors of different sizes explode by applying reverse voltage. The larger ones have a safety vent, which I block to make them blow up instead of just releasing the magic smoke in a small stream... The voltage rating of the caps ranges between 10 - 450V and capacitance of 4,7 - 5700µF. Mostly electrolytic capacitors, but also a tantalum capacitor.
