data to follow:<br /><br />16 Capacitors 470 and 1000 µf were frozen in an ice block to see what would happen under excessive voltage.<br />First 70 Volts 50Hz was applied, ice did crack but not shatter. Circuit went open.<br /><br />Defrost Caps and try again in air which yielded in smoke.<br />I decided to finish the Caps of with a bit more voltage.<br />Then 170 Volts was applied which gave some sparks and crackles.<br />I missed one good bang when I forgot to turn the camera on.<br /><br />A word of CAUTION !!<br /><br />These experiments are dangerous and should not be copied by inexperienced people.<br />A safety shield and goggles are a minimum requirement as well as outside location as the fumes are not good for ones health.
