Science was always one of my favorite subjects in school; not just because I learned a lot of cool facts about the world around me, but because I got to see things that I wouldn’t otherwise come in contact with in my everyday life. Experimenting can be a lot of fun, especially if you have no idea what the outcome will be.
Lots of people like science, and thanks to sites like YouTube, we have more access now than ever before. You can find videos on outer space, chemical explosions, lasers, micro-organisms, and stuff I don’t even know about. Never mind what goes on inside a high school classroom, YouTube has a lot more to offer.
In this article, I have pulled together 5 videos of some pretty cool science experiments.
If you search for ‘cool science experiment’ on YouTube, Steve Spangler will absolutely dominate your search results. He’s a celebrity teacher of sorts, as well as a speaker, author, and television personality.
Some of the experiments he does are pretty low-tech in my opinion, but every once in a while he brings out the big stuff. This is a really cool video in which Steve went on a news program and demonstrated his liquid nitrogen explosion.
Here’s something most of us would never get to see without YouTube. This video of a cool science experiment takes place on a space shuttle in micro-gravity. An Alka-Seltzer is added to a spherical water droplet and it goes absolutely insane. I really like how it just dissolves instantly and comes to an equilibrium gradually. I guess that’s how it settles your stomach.
Dry ice is always fun to play around with. In this video, this guy shows you how to make a giant dry ice bubble with just a bowl, soapy wash rag, and of course, dry ice. It actually puffs up pretty big before finally popping and clouding up the room, which in turn makes it pretty cool.
4. Liquid Light
Remember those glow sticks everybody used to run around with during Halloween? Everybody always wanted to know how they work. Well in this video, you can discover how they work, as well what you would need to do to recreate the experience yourself and make “liquid light”.
They also experiment with mixing the different colors together to see if the end result is a white liquid as predicted.
Last but not least, the cool lemon battery science experiment. Did you know that you could turn a bunch of lemons into a powerful enough battery to light an LED bulb? In this video, you’ll get to see just that, as this guy hooks lemons together to form a battery. He even powers a calculator. Think of it as a last resort if you’re out of batteries and in an emergency of some kind.
And there you have it. Now you probably have a conversation starter or two for your friends. You can ask, “Did you know you could use lemons as batteries?” or “Do you know what happens to Alka-Seltzer in space?” You can find videos on these topics, and everything in between, on YouTube. Just type in what interests you most to pull up related videos.
