With the help of the Backyard Scientist’s actual backyard (and, more importantly, pool), Rober tested his hypothesis: That he’ll only sink to his waist. Technically, Rober lost the bet, but that doesn’t necessarily mean his coworkers won. If there are any winners in this video, it’s Rober’s nephews, who he invited over for a swim after proving himself wrong. At least, this time, he’s not pelting them with a snowball machine gun. With only a little bit of the summer left, you can conduct a similar experiment with your kid, too. But Nerdist broke down the math and it could take upwards of 167,000 packets of Orbeez and 15,600 gallons of water to achieve similar results. In other words, if you live in California, trying this is going to make you look like a real dick. But if water is not an issue, you’re still going to need a pool … and a crap load of patience.
