This is Kevin Kohler, AKA The Backyard Scientist. His YouTube channel consists of Kevin conducting weird and crazy experiments, all from the comfort of his backyard. He must be doing something right, too, because his channel has over 3 million subscribers. Dang, people must really love science! Well, they may not love science class, but they do love watching Kevin's backyard science class. And I can see why. It's easy to love science when you're watching some young guy conduct some wild, cool, and real experiments in his own backyard.
Here's where I feel like I should say...PLEASE don't try this at home, kids! Kevin's parents may have signed off on all of these crazy (and dangerous) experiments, but yours probably wouldn't. Also, Kevin actually knows what he's doing, so enjoy his videos but don't actually try to copy them with the appropriate parental supervision. Okay, I'm done being a lame adult. Let's check out some cool science experiments!
One of his videos is called "Pouring molten aluminum into a pool!!" If you start watching Kevin's videos, you'll quickly discover that he loved molten aluminum...and I don't blame him. It's pretty dang cool. In this particular video, which he posted back in 2014, Kevin starts by pouring charcoal into a metal trash can. Seems simple and boring, right? Oh, baby, you have no idea.
I think I should also mention that this video has garnered over 20 million views over the years. Go science! Whatever high school bullies picked on the science nerds are eating their mean words, now!
He then got some aluminum and put it in another canister on top of the charcoal. And then set that coal on fire. Oh yeah, now things are heating up. This is where it starts to get really good. What do you think happens next? If you're thinking something along the lines of...MOLTEN ALUMINUM, you'd be right!
What happened to the aluminum? It made its way down to the bottom of the pool, and then cooled off to form these shapes. Fortunately, our man Kevin made sure to get an underwater camera to capture these cool moments.
And that's what happens when you melt down over five pounds of aluminum and dump it in a pool. On a similar note, we also recommend checking out one of his other videos, "Pouring Liquid Nitrogen in a Pool."
The Backyard Scientist has a ton of cool videos that anybody even mildly interested in science would appreciate (even I went down the rabbit hole once I discovered his YouTube page, and my worst subject in high school was science!)
One of Kevin's more recent videos was about the making of a giant mouse trap powered car. We've all heard of the Bat Mobile, but I bet you haven't heard of the Rat Mobile!
