My 9yo brother loves that crazy Russian hacker dude. That coin stacking experiment reminds me of when the Mythbusters simply interlaced 2 phone books page by page...

Cool video.

For those unaware, dry ice is solid (frozen) carbon dioxide. Carbon dioxide is one of the relatively few materials that will undergo sublimation. This happens when a compound moves from the solid state (dry ice) to the vapor state without melting into a liquid between phases.

My guess is that the latent heat retained in the quarters starts to boil away the dry ice on the surface and that the vibration of the quarters is due to the expansion of gas that forms upon sublimation. This is similar to the process of cooking when one brings water to a roiling boil.

The old "dancing" coin thing!

I didn't know coins shiver when they get cold.

Interesting.... I believe TomB has the correct analysis....that is also why the coin stops 'shivering' when it attains the same temperature as the ice.... Cheers, RickO

TomB, spoken like a true chemist. Takes one to know one.

So glad to hear that. I thought they were shivering from the cold until they died of hypothermia.

Cool change. I reckon silver and copper coinage would do the same until they reached equilibrium with the dry ice.

Lets try a conga line of Morgans.... Cheers, RickO

Don't try this at home kids
Dry ice is about -110 degrees F.
You can touch it briefly with bare hands, otherwise use an oven mitt or protective gloves.

Otherwise it will freeze your skin cells and give you a burn injury.
