    This toilet question is actually one I don’t instantly have an answer to. My guess is that nothing major would happen. I believe that there’d be a some systems which would overflow or break due to the pressure on the system, but nothing major would happen because the earth’s pressure is pretty easy to go back to the normal range. Earth’s pressure fluctuates naturally so I guess nothing major would happen if every toilet was flushed at the same time... actually, just less air for people climbing Mt Everest 😂

    answer to class #4: 1. If you put a hydrophobic coating on your hand, maybe an aerogel cream or something like that. There are companies in aerogel research who’ve come up with some very cool stuff. If you do that, you’re basically coating your skin in a layer of ‘air powder’. Really wacky stuff there. 2. If you electrolyze water, it’ll turn into two hydrogen atoms and one oxygen, both pure gasses. If you put your hand into a cup of electrolyzed water, it will come out perfectly dry. It’s just air at that point. But don’t be next to heat when you do that! Putting your hand into a cup of pure oxygen and hydrogen next to an open heat source is a recipe for some very nice fireworks and a trip to the ER. 3. The Leidenfrost effect is such that if you get your hand hot enough, there will be a thin pocket of pressurized steam around your hand that will prevent any water from touching it. This is the effect that allows little drops of water to bounce around in a really hot pan. Shout out to Mark Rober! I’m 15, I live in Israel, and you’re my favorite channel!

    Hi Mark, could you please read comments and use answers to the weekly questions in the giveaway too? there are a lot of great answers here, and I think that could really benefit the community. I for one don't have social media to post on. I'm a kid. I think a bunch of us are in that situation, but that doesn't mean we don't have good answers to give.
