Tuning Fork Demonstrations Will Blow Your Mind

Most people know what a tuning fork is, but do you really know what’s going on with a tuning fork? It’s not just a simple musical tool. Physics teacher James Lincoln of Arbor Scienific demonstrates ten awesome tuning fork experiments that will blow your mind in this trending video

Sprinkler During Canadian Winter Is Basically A Fog Machine

The Internet has seen what happens when you throw a cup of boiling water when the temperatures are far below zero outside. The water instantly turns to snow. But Al Paul and his Canadian family have taken this concept to the next level. When an arctic blast took temperatures down to -50 degrees, the family set up the sprinkler and turned it on. Not a drop of water came out. Instead, it turned into an instant fog machine! Awesome!

Schlieren Optical Technique Incredibly Shows The Flow Of Heat And Gas

Using Schlieren flow visualization, Harvard Natural Sciences Lecture Demonstrations can show small changes in the air that would usually go unseen by the naked eye. By pointing a light at a concave mirror and focusing the light onto the edge of a razor blade in front of a camera, the heat of a candle or helium from a balloon can be seen. Incredible!

NPR covered this technique back in April.

Non-Newtonian Fluid In Slow Motion

A non-Newtonian liquid is a complex paste or slurry that isn’t quite a solid or a liquid. It can actually exhibit the properties of both a liquid and solid depending on the circumstances. Gav and Dan of The Slow Mo Guys made a homemade non-Newtonian fluid simply using water and corn starch. The gloppy goop is both runny and thick. Weird. They put their concoction on a speaker playing music and hit record on their super slow motion camera. The resulting video is trippy to say the least.

Space Station Astronauts Put GoPro Into Floating Water Bubble

Astronauts spend their time on the International Space Station working on science experiments that can only be done in zero-gravity. But it’s not just hard work and number crunching. In this new video by NASA’s Marshall Center, a group of astronauts create a large bubble of floating water and then put a waterproof GoPro camera inside it. You know, for science!
