Video: Making plasma by microwaving a grape is the coolest thing

The Backyard Scientist’s slow motion series is always fun because they’re just quick and easy experiments that show off cool tricks you can do at home (don’t do it at home). This time he makes plasma with a microwave oven transformer (which creates a super cool arc of plasma around the blue bolt of electricity) and…

Incredible music video shows how science experiments react to music

Sound makes funny shapes. We don't usually see it in real life but when you put together water and sand with speakers bumping at different frequencies, you'll start seeing spirals and kaleidoscopes and other wild objects. This new video by Nigel Stanford and directed by Shahir Daud features all those awesome cymatics…

Here's liquid nitrogen turning into solid nitrogen in an extreme vacuum

What happens when you put liquid nitrogen in a vacuum chamber? It turns solid. And then it snows. As the vacuum lowers the pressure in the chamber, it decreases the boiling point of the liquid nitrogen which means the nitrogen boils faster. But! The boiling liquid nitrogen is also evaporating which cools itself which…
