Ferrofluid + Glow Sticks – The Physics Girl

Ferromagnetic + fluid = ferrofluid, a liquid containing nanoscale particles of magnetite, hematite, or an iron compound. Invented by NASA's Steve Papell in 1963, ferrofluid forms undulating spikes and patterns as it r...

Extreme Gs in a centrifuge – Simulating gravity on other planets

What is it like to feel gravity on Neptune or Jupiter, or to experience the G-forces that astronauts endure when they're returning to Earth in the Soyuz? In this clip from episode 3 of Wonders of the Universe, Pro...

Biisuke Ball’s Big Adventure – Pitagora Suitchi

The Dresser – Joseph Herscher

An alarm clock goes off. Dropping it in a glass of water will silence the alarm. The weight of the glass also triggers a machine which helps the user get dressed... Shirt, pants, vest, socks, shoes... and don't fo...

Hot & Cold Water Science Experiment – HooplaKidzLab

With two matching jars, red and blue food coloring, some hot and cold water, an index card, and a dish or baking pan, you can observe how the different densities of hot and cold water behave. This experiment by Hoopla...

MorpHex MKIII, the glowing, transforming robot

Glowing with programmed LEDs, rolling around in "spheremode" with twelve synchronized shell sections, and walking as a hexapod robot, this is MorpHex MKIII, the transforming robot, made in 2014 by kinematics expert Kå...

The Inverted Glass Harp

We love glass harps – instruments made from wine glasses that are filled with different amounts of water to create a series of desired pitches. In The Inverted Glass Harp, Dan Quinn shows us that empty glasses can als...

Adding color & fizz to floating water bubbles in microgravity

When you're floating water bubbles in microgravity on the International Space Station, be sure to add a gas-releasing effervescent tablet and some food coloring, and don't forget to film it in 4K resolution. Astron...

Exploring Space with Shape-Shifting Robots

Can a "skwishy" baby toy help inform how next generation robots explore other worlds? Vytas SunSpiral's team at NASA Ames Research Center joined forces with Alice Agogino's Mechanical Engineering lab at UC Berkeley to...

Why do spinning rings & spinning disks have different paths?

In this silent video from Science Magazine, we can see how a spinning disk and a ring create two different paths while spinning. Try it at home. Do you see the same result? David Schultz at ScienceMag.org explains: ...

Jelly Tennis – The Slow Mo Guys

When Gav and Dan were told about a still photo that showed Jell-O (or jelly in the UK) being hit by a tennis racket, they decided to recreate it in slow motion. This Slow Mo Guys video is the colorful, sticky, splatte...
