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...
Science Extras from Jiwi’s (Rube Goldberg) Machines
A YouTube series that hearkens back to characters and situations from old silent films, Jiwi's Machines mixes a love for Rube Goldberg Machines with an ode to comedy greats like Charlie Chaplin or Buster Keaton. T...
How shock absorbers work, an under the car view
What happens under your car while you're driving in it? YouTuber ChrisFix put cameras under his car to see what was happening when he drove his 14 year old shock absorbers on a bumpy roadway, a highway, in stop and go...
Andrew Gatt’s Ultimate Paper Roller Coaster
Perfect for the classroom or at home, Andrew Gatt's paper roller coasters are not only fun, but they also teach so many lessons in engineering, construction, teamwork, trial and error, and more. In exploring physics a...
Zinnia – A dizzying spring-driven kinetic sculpture
Clayton Boyer's Zinnia spring-driven kinetic sculpture is an optical treat as its two 24 inch (61 cm) diameter wheels change speed and direction. Watch as he briefly winds it for a dizzying quick spin demonstration. ...
How to Observe a Meteor Shower – Cal Academy
Get some blankets, find a dark hill on a dark night, make sure you've napped, and put away that smartphone. The California Academy of Sciences has some excellent tips for seeing shooting stars, more accurately known a...
A pendulum wave demonstration with bowling balls
Thanks to these 16 bowling balls hung from a 20 foot wooden frame in the mountains of North Carolina, we can see what a large-scale pendulum wave apparatus looks (and sounds) like. Filmed by Maria Ikenberry, she also ...
How to make a Popsicle Stick Chain Reaction
Have you seen that crazy popsicle stick chain reaction video in the archives? This Sick Science tutorial explains how to make it. Why does it work? The key to the Popsicle Chain Reaction comes from potential and ki...
Citadel Physics: Wave Pendulum
jtotheizzoe: Get hypnotized by this wave pendulum… seriously, I can’t look away. A wave pendulum like this is built of equally weighted objects suspended by different (and carefully cal...
Andrew Gatt’s Paper Rollercoasters
Mixing physics, engineering, paper and what looks like some seriously rewarding folding, cutting and taping DIY, Andrew Gatt builds incredibly sturdy paper roller coasters out of heavy paper s...
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 heart of it. When the arm of any...
Energy 101: Wind Turbines
An Energy 101 video from the US Department of Energy: the modern wind turbine and how it generates clean electricity using physics and technology. Watch more videos about wind.
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, but also because of ...
The time lapse assembly of wind-power turbines
We’ve always loved the super tall wind-power turbines while speeding by on a train or in a car. Reaching tall into the sky, they are a marvel of sustainable kinetic power and so the kid often asks for videos of...
Cobra Weave Exploding Stick Bomb: a popsicle stick chain reaction
Whoa, how did we miss this?! This is a popsicle stick weave chain reaction called the “Cobra Weave Exploding Stick Bomb,” and you can do it yourself following an Instructables How T...
