The Amazing Dry Ice Experiment

One of our readers just sent in an interesting (scientific) video clip that shows what happens when you combine dry ice with liquid soap. Watch after the jump.
Dry ice is produced by compressing carbon dioxide gas to a liquid form, removing the heat produced by the compression (see Charles's law), and then letting the liquid carbon dioxide expand quickly. This expansion and the high-speed evaporation of carbon dioxide gas cools the remainder of the liquid down to the melting point, where some of the CO2 freezes into 'snow,' which is then compressed into pellets or blocks

you're both wrong, they did not use hydrogen on mythbusters, they used methane

u all wrong, hydrogen is way to explosive to light like that, mythbusters used methane gas, and they just got some water and washing up liquid, no ice involved and they just pumped methane gas below the water

there's this issue about who's saying who's wrong? what is it all about? does it make u feel superior? smarter? does it feed your arrogance? practice some humility and politeness and make the world a nicer place to live in.
