The Physics Behind Four Amazing Demonstrations

David Willey explains why walking on broken glass, dipping fingers in molten lead, lying on a bed of nails with a concrete block broken on your chest, and picking up an orange-hot space tile are not as dangerous as they appear.

He also walked on fire.

So, the next time you see something extraordinary, before attributing it to supernatural forces or superhuman abilities, think of physics or tricks first.  If you rule out all natural explanations, you can apply to win US$1,000,000 at the One Million Dollar Paranormal Challenge.

P.S.  Mr. Willey also has a list of interesting demonstration of the laws of nature at his "How Does A Think Like That Work" page.
