On a visit to Hyperloop One, a Los Angeles-based team working to create a near-vacuum tube-based transportation system, Veratasium's Derek Muller got to check out this Electromagnetic Levitation Quadcopter demo. In th...

An origami-inspired model for reconfigurable materials

Metamaterials — materials whose function is determined by structure, not composition — have been designed to bend light and sound, transform from soft to stiff, and even dampen seismic waves from earthquakes. But each...

What can you do with a large neodymium magnet?

Neodymium magnets are really strong. The larger they get, the more careful you need to be to avoid being pinched or struck from the force of their attraction. This video from Magnetic Games cautiously explores what ca...

The toy-inspired Paperfuge, an innovative new tool in healthcare

Bioengineer and Stanford researcher Manu Prakash has developed another inexpensive scientific device. The Paperfuge is a hand-spun, ultra low-cost, paper and string centrifuge that was inspired by the ancient whirligi...

The synchronization of 100 metronomes

From the Ikeguchi Laboratory in their pursuit of studying nonlinear chaotic dynamics, watch as 100 metronomes synchronize to the exact same timing. The key is the surface that the metronomes are on: a hanging platform...

This nine foot tall wooden sculpture of San Francisco was made with glue and 105,387 and a half toothpicks. It was built by Scott Weaver who, stuck at home at the age of 14 with spinal meningitis, started working in e...

Why does a frozen lake sound like a Star Wars blaster?

Ice can make all sorts of sounds: cracking, crackling, musical booooooms... and that pew! pew! Star Wars blaster sound. How? In this episode of NPR's Skunk Bear, we learn about acoustic dispersion and how the phenomen...

A home made string shooter & slow moving waves in rope

This string shooter uses two wheels on motors to push a string forward while a tube guides the string back through the wheels, creating a constant loop that appears to defy gravity and demonstrates wave phenomena. ...

Entropy and the Arrow of Time

As we experience it, time flows in a single direction. This is what we think of as the arrow of time, which stretches from the big bang to the present, and off into the future. But our experience of time doesn’t ma...
