It ’s not everyday that you combine weird physics with defunct medical equipment and get a success . ( Although I would love to see one of those oldtobacco - smoke - up - the - butt bellowsfilled with nitroglycerin . ) The affair that looks like a pizza - pinnace is a Wartenburg Pinwheel , an old piece of neurologic equipment that measure nerve reaction . It allows a doctor to slowly and systematically run it along a person ’s body to suss out for numbness or sensitivity . Today , because it is so difficult to decent clear , it has mostly been retired from medical work .

The little plumes of purple fire shoot out of it are corona discharge . fundamentally , enough of an electrical potential derived function will ionise the air nearby . The electrons in the air will derive loose from their atoms and swim around in a blood plasma . This makes it very easy for electricity to move through the airwave . The energy of it all excites the line molecules which give off a radiance . In this case , the glowing shoot from each of the spike of the wheel .
But Wheel of Purple Fire sounds well .
