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 (13.5 kilograms) 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 swimming pool to show off the eerie white fog produced when the dry ice hits the water and sublimates, or turns 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 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!"
Considering that CrazyRussianHacker's video has already racked up over 3.4 million views, it most certainly qualifies as a viral success.
This isn't the first time someone decided to drop a bunch of dry ice into a swimming pool and post the video on YouTube. YouTube user Ken Corless dumped 60 pounds of dry ice into a swimming pool and posted the video in 2007. Corless did the experiment again in 2011, this time using 200 pounds of dry ice.
As cool as it looks, this might be also a good time to remind people not to swim in dry ice while it's in the pool. Skin can burn when it comes in direct contact with the dry ice.
