When dropping dry ice into a swimming pool for the first time, it's best to start small. In this case, watch a video from YouTube user Esther Thomas who captured footage of a family dumping 10 pounds (4.5 kilograms) of dry ice into a small, above ground pool for a kids' MythBusters party. "I don't know if this was such a great idea," someone says off-camera. With over 2 million views since 2013, this experiment seems to be a viral video sensation.
Now let's see what happens when you double the amount and put 22 pounds (10 kilograms) of dry ice into a swimming pool. South African YouTube user Daniel Eugene Botha did just that in his video from 2015. Not only does he dump the dry ice into the pool, but he puts on swimming goggles and takes an underwater selfie in it.
YouTube user CrazyRussianHacker posted a video in May 2016 showing him adding 30 pounds (13.5 kilograms) of dry ice to a swimming pool full of water, with impressive results. The best part of the video -- which has more than 13 million views -- isn't the dry ice giving his pool an eerie ambiance, but how excited he got during the process. "It looks like a volcano underwater," CrazyRussianHacker says. "I think this is definitely a success. So awesome!"
In this video, shot in 1999 (but posted in 2007) from YouTube user Ken Corless, we see what happens when a 60 pound block (27 kilograms) of dry ice is thrown into a hot tub/swimming pool combo. And yes, that's someone sitting in the water and not a floating human head. The video went viral with more than 7 million views.
When YouTube user RussianVolcano posted this video in 2014, a normal swimming pool takes on a much more sinister look after adding 110 pounds (50 kilograms) of dry ice to the water. Even when kids are playing in it, the evil mist appears to engulf their legs. Nope, not creepy at all. Plus, it went viral gaining over 1 million viewers.
Watch Korean YouTube star Heopop drop 132 pounds (60 kilograms) of dry ice in a swimming pool. The best part of the video, watching him ride an inflatable pink flamingo raft across the bubbling water and freak out about how scary it looks. I could watch Heopop and his pink flamingo frantically swim in dry ice all day.
Apparently, dropping 60 pounds of dry ice into a hot tub wasn't exciting enough for YouTube user Ken Corless so he made a sequel video in 2011 where he dumps 200 pounds (90 kilograms) -- in the form of 60 pound (27 kilograms) blocks one at a time -- of dry ice into a swimming pool. The parents yelling at their kids to be careful while swimming in the dry ice pool makes it even more hilarious to watch. Plus they do a few more experiments including drink dry ice-enhanced beverages with the added commentary, "Drink some. You'll be famous because you'll be on YouTube." The video beat his last record with an impressive 9 million views.
YouTube user ScanGauge decided to go even further by dumping a staggering 350 pounds (159 kilograms) of dry ice into a swimming pool, in a video post in 2014. Side note, if you plan to have your friends help you drop that much dry ice into your swimming pool make sure your phone is recording the video before they start the process. Because they dumped so much dry ice into the swimming pool, it also spilled over into their yard, which probably made the neighbors think the Addams Family moved in next door.
If dumping dry ice in your swimming pool doesn't sound thrilling enough after watching these videos, how about dropping some dry ice bombs instead? YouTube user TheBackyardScientist explains how to create underwater explosions using dry ice bombs. In this video from 2015, get the lowdown on how to make these dry ice bombs -- just fill an empty plastic bottle with broken pieces of dry ice, add a weight, screw on the top, and then quickly throw into the swimming pool. During the experiment, TheBackyardScientist strongly cautions that people not be swimming in the pool when the dry ice bombs explode.
YouTube user CrazyRussianHacker shows viewers -- over 13 million -- how to have learn more about dry ice with eight different experiments. Get on your gloves and safety goggles first. In his 15-minute video, which was posted in 2014, he shows us step by step how to make dry ice, liquid nitrogen, a giant dry ice bubble, tiny dry ice bubbles, dry ice smoke rings and more.
When CrazyRussianHacker's dry ice bombs don't explode, he cautiously uses a golf club from the outside hallway to hit it and makes it explode much to his delight.
Like all of CrazyRussianHacker's videos, it's his infectious enthusiasm that makes his videos so much fun to watch. In this part of his 8 Dry Ice Experiments Compilation video, his kitchen sink overflows with dry ice in action.
