Harvard’s classic pendulum waves demonstration

A Harvard Natural Sciences Lecture Demonstration of 15 uncoupled simple pendulums of monotonically increasing lengths swing for a minute and a half, a physics video classic. The period...

Quantum Levitation: A mind-blowing demonstration and explanation

Quantum levitation. “Superconductivity locked in space,” a phenomenon known as quantum trapping. You can see more details in this Quantum Levitation video by Quantum Researcher Boaz Almog:...

Aluminum foil boat floating on a sulfur hexafluoride sea

...can pour it into a glass container and float a light-weight aluminum “boat” on its gas “sea.” Watch this demonstration at the Physikshow of the University of Bonn. Check out...

Melting gallium spoon: It melts as you stir with it

Kids, remember Gallium from this video? Then let’s watch this spoon stir. This spoon made from 99.998% pure gallium metal melts at 86F/30C! Great for demonstration purposes (chemistry/physics...

Euler’s Spinning Disk

We love this video of Euler’s (sounds like Oiler’s) Spinning Disk, not only because of the physics behind how long it spins on the slightly concave mirror base,...

The Apollo 15 Hammer and Feather Drop on the moon (1971)

The Apollo 15 Hammer-Feather Drop: At the end of the last Apollo 15 moon walk, Commander David Scott (pictured above) performed a live demonstration for the television...

Physics! 32 out-of-sync metronomes synchronize

A physics demonstration from the Ikeguchi Laboratory in Japan: Exactly 32 metronomes unite in synchronous play with no help from human hands. And there’s simple physics at the...

A red hot ball of nickel is dropped in a cup of water

A red hot ball of nickel is dropped in a cup of water, resulting in a most unexpected reaction, in this demonstration of the Leidenfrost effect by...

Rotating Saddle, a physics demonstration

Rotating Saddle (and the science behind it) from the Harvard Natural Sciences Lecture Demonstrations team: A playground ball finds stability in a saddle when the saddle is rotating at the...

Instant Ice Crystals – The Secret Life of Ice

Ice crystals can form quickly in supercooled mineral water, freezing the liquid almost instantly. In this clip from the BBC’s The Secret Life of Ice, science writer Dr....

Wave Pendulum – Citadel Physics

...fair project? This would be a great one. Dr. Joe Hanson muses on this excellent wave pendulum demonstration from The Citadel Department of Physics. Watch more pendulum videos on this...

A Basic Demonstration of Optical Cloaking

Above, A Basic Demonstration of Optical Cloaking. Cloaking is a term for hiding an object from view at specific frequencies, but evidently one can cloak things DIY-style with  four mirrors...

The most amazing thing about domino chain reactions

...1.5x larger, the last domino would be the height of the Empire State Building. There are more chain reactions and many, many physics videos in the archives.  via Physics Buzz....

Newton’s Beads: A physics demo by Steve Mould & Earth Unplugged

...happening by a nalyzing  the video using physics. For more, check out science writer   Aatish Bhatia’s calculations on what’s going on  in Steve’s demonstration. Update: Here’s an equally fascinating follow-up...

GE’s Six Second Science Fair, a compilation

DIY experiments and videos are two of our favorite things, so we were thrilled to hear about GE’s Six Second Science Fair. The week-long celebration resulted in over...

Leidenfrost Maze: Self-propelled droplets on a hot jagged surface

...though we’re guessing every school around the world would love a physics demonstration kit like this. There are more excellent physics videos in the archives.  via PopSci, thanks @kvetchup....

The Floating Water Bridge Demo

more images at Dr. Fuchs’ site. Bonus vid: density fluctuations. In the archives: more physics videos and more demonstrations like this: an aluminum foil boat floats on a sulphur hexafluoride sea....

Not finding what you're looking for? A few suggestions:
• Fewer words might give better results. Look up cats instead of funny cats.
• No need to search with the words videos or for kids included.
• Use related words: If searching for iceberg isn't working, try ice or glacier.
• Is everything spelled correctly?
• Browsing topics might help, too!
