In this article you’ll see some of the coolest science videos on the Internet with links (where applicable) to an in-depth explanation of the experiments seen in the videos. Have fun reading and watching. Do you know any more videos that should belong in this article, please feel free to post them with a link in the comments below!

1. Musical Tesla coil

This is a solid-state Tesla coil, a device invented by Serbian-American scientist Nicola Tesla.You might have seen one of these before, but you probably haven’t seen them playing music. Listen and watch to the sound of electricity. 

2. Fun with a bar of soap and a microwave

Do a search on YouTube on the word ‘microwave’ and you’ll find a numerous amount of videos of people microwaving all kinds of stuff. ‘Been there, done that, have seen it all’ you might think, but take a look at the next video, it’s quite funny. In this video a bar of soap is being microwaved. The results are pretty fluffed up, I would say.

3. Fun with chemicals

As a kid I thought inhaling helium and listening to the effects on my voice was big fun. I didn’t know of sulfur hexafluoride by then… you just gotta love this. Watch and learn from the next video in which you’ll not only see the effects of both helium and sulfur hexafluoride being inhaled but you’ll also understand why these effects occur.

4. Fighter jet in disguise

The next video shows a F-14 Tomcat and the effects of the so-called Prandtl-Glauert singularity. Due to a drop of air pressure caused by the jet traveling at transonic speed a condensation cloud forms around the aircraft. You can try to observe this effect at home by successfully cracking a whip on a humid day. A visible cloud is produced at the point where the tip of the whip goes transonic.

5. Vibrating colors

In this experiment several clear liquids are combined. The glass with liquids is put on a vibrating stand. Under the influence of the vibrations the mixture quickly changes colors — back and forth — over and over again. This is called the Briggs–Rauscher oscillating reaction.

6. Foam galore

These students have fun with some hydrogen peroxide, potassium iodide, and dish soap. The result is a blob ‘elephant toothpaste’ as they call it. 

7. Leaping shampoo

Take a look at this beautiful footage of leaping shampoo. Yes, leaping shampoo, that’s correct. The scientists who made this video explain what is happening here. It’s called the Kaye effect and it can be observed in common household products like shampoo, liquid hand soap and non-drip paint. The problem is it seldom lasts longer than 300 milliseconds. That’s why this video is shot with a highspeed camera. Scientifically interesting and of great aesthetic beauty!

8. Look who’s calling

We’ll end this article with yet another experiment with a microwave. Instead of soap, we’ll see a cell-phone being microwaved. And this time the experiment grows a bit out of hand. Don’t try this at home!
