See what happens when guy dumps 30 pounds of dry ice into a pool - CNET

Dry ice is often used as a cooling agent in preserving food, but it also has other applications, including preventing insect activity, loosening asphalt floor tiles and altering cloud precipitation. Add dry ice to water, and dense white fog occurs, which makes for a rather spooky visual effect.

On Friday, YouTube user CrazyRussianHacker posted a video showing him adding 30 pounds of dry ice to a swimming pool full of water. Wearing gloves to protect his hands, he crushes blocks of dry ice bought from the grocery store in a cooler.

Then he pours it into his infinity swimming pool to show off the eerie white fog produced when the dry ice hits the water and sublimates -- tus from a solid to a gas.

The best part isn't the dry ice sublimating in the swimming pool; it's the constant excited commentary coming from CrazyRussianHacker, who can't help but geek out over his experiment.

"It looks like a volcano underwater," CrazyRussianHacker says. "I think this is definitely a success. So awesome!"
