It’s Geek Week on YouTube (s goog). The skateboarding dogs and cute kittens are out of the spotlight, replaced by explosions and mind bending experiments. In honor of today’s status as Brainiac Day, I handpicked 10 of the most interesting and awe-inspiring videos on the site.
10. Building a giant robot mech
Wired takes us through the steps of building and piloting a huge robot.
9. Pitch tar drop falls
Is pitch, AKA asphalt, a solid or a liquid? It appears solid, but when placed in a funnel, it drips roughly once a decade. Physicists at Trinity College in Dublin waited 69 years to finally catch their pitch experiment drip on video camera.
8. Science Bob releases 2,000 ping pong balls in simulated zero gravity
Because floating in a plane flying in parabolic arcs isn’t fun enough, Science Bob and a gang of teachers decided to release a cloud of orange ping pong balls.
7. The Large Hadron Collider explained via rap
Physics is cool. So are the ALICE, CMS, LHCb and ATLAS experiments at CERN. Science journalist Katherine McAlpine thought so too, so she wrote a rap song.
6. Colorful droplets collide in super slow motion
At 5,000 frames per second, candy-colored liquid takes on an artistic quality as it splashes and breaks apart.
5. Tesla coils sing
Tesla coils produce lightning-like snakes of energy. This is what happens when you tune their accompanying sounds to create music.
4. Apollo 11 lands on the moon
It’s been more than 40 years since NASA first landed on the moon, but the moment of touchdown still feels tense and exciting.
3. Chris Hadfield sings “Space Oddity” on the International Space Station
It’s hard to pick just one Hadfield video. During his six months on the International Space Station, he showed us what it’s like to cry, wring out a towel, sleep and make a peanut butter sandwich in space. He capped off his time there with a cover of “Space Oddity” — the perfect song for a lonely astronaut.
2. Neil deGrasse Tyson on the most astounding fact of science
We are made of stars.
1. A trip across the universe
Feeling small today? You should, as this video demonstrates by zooming back from the Earth to convey its size in relation to the greater universe.
