High-Speed destruction : Can Crushing

Movie : can1.m1v (1.3MB)

Aluminium can, using coil made of 3mm copper rod, sleeved in polythene tube. Power around 1.5KJ.
Probably 1000 frames/sec - we were messing with external sync & can't be sure....!

Dark band visible, probably due to magnetic field interfering with camera. Slight crushing starting to become visible at bottom of can.wpe58.jpg (18499 bytes)

1ms later - coil has pinched together and can-crush is pretty much complete

Crush spreads out - probably due to springiness of can

Coil starts to recover shape, can now pretty stable
