AJI Posted July 29, 2008 Share Posted July 29, 2008 Some physics/chemistry type thing in action : http://video.google.co.uk/videoplay?docid=8320026794801548475&q=amazing&ei=79COSL-OBpHKwgPm98CZCA&hl=en I am thinking liquid nitrogen/oxygen or whatever is being used... but we never did this experiment at school.

johnny g Posted July 29, 2008 Share Posted July 29, 2008 It's superconductivity if I'm not mistaken? Some materials have a specific point at which the resistivity changes. That's pretty much all I know about it... Link to comment Share on other sites More sharing options...
d4rr3n Posted July 29, 2008 Share Posted July 29, 2008 Yep part of superconductivity, specifically the meissner effect. There using liquid nitrogen to cool the superconductor which changes its properties into a diamagent, this cancels all the flux lines inside it an causes it to become suspended like in the video.
