What, no mentos in a soda bottle?

(Thanks, these are cool.)

This is my favorite, but I dunno if that counts as physics or chemistry or what.

That Tesla coil is incredible. I was expecting a 808 to kick in halfway.

Why haven't giant Ruben's tubes become a mainstay of rock concert pyrotechnics? Someone is asleep at the switch.

Those are fantastic! How does the tesla coil soundwave one work? I don't get it...

The cornstarch (GooseOnTheLoose's link) is remarkable -- the end... creepy, almost.

I'd like to see slingshot girl on the list somewhere.

Make sure to note the credits to the rap song at #1.

(Oh, and Turtles, this is an awesome post, IMO.)

I think this video exhibiting the properties of a non newtonian fluid is pretty rad.

A great collection. Thanks.

Can someone explain to me...

This concerns the mythbusters helium/SFl6 inhalation bit. So speed of sound goes inversely as density, and causing the high voice with helium. But, everything I've read suggests that deep-sea divers (breathing a He and O mixture) have the same high-voice problem. Wouldn't their gas be under many atmospheres of pressure, and so have a high density, and so lead to a very low voice?

The gas itself is still less dense than nitrogen (which is what it replaces), even at depth. See here:

Because the mass of helium gas is less than that of nitrogen gas the vocal cords vibrate at a higher rate in the voice box, this coupled with the higher speed of sound for helium results on a very high pitched voice when the diver breathes the helium oxygen gas mix.

Which also notes that hypothermia is a greater danger as well, since Helium conducts heat much better than Nitrogen...
