The Physics Behind Four Amazing Demonstrations Here is the physics theory behind four dramatic demonstrations - walking on broken glass, dipping one's fingers in molten lead, breaking a concrete block over someone lying between beds of nails, and picking up an orange-hot piece of silica tile.

Even though the physics behind such a thing are sound, the thought of dipping my fingers into molten lead makes my stomach go all fluttery.

Thanks, matteo. This was very interesting.

This is a great link, matteo. Thank you.

Entirely sweet. The only one they missed (which isn't dangerous) that I like to see is the can implosion one... Well, and the shattering with liquid N.

If these skeptics were so smart, they'd stop beating the shit out of themselves and each other and go after the religious nuts.

The hand in molten lead one works in reverse too. I used to put my hand in liquid nitrogen as part of the christmas cectures at ubc (after freezing and shattering a rose, of course).

if these skeptics were really smart, they'd do my bidding, not yours.

Is this the same guy who demonstrated walking on glass and hot coals on an episode of Penn and Teller's "Bullshit!"?

He totally stole that first one from Annie Lennox.
