Not Quite Cutting-Edge
But still pretty neat. A 15+ minute video of someone making vacuum tubes by hand.

On the Topic of Unstable Equilibrium
Most of what follows falls (as it were) under the heading of “what happens when you fail to keep the center of mass above the supports.” The “ooh, that’s gonna leave a mark” cringe-o-meter registers noticeably in some scenes.

Driving Me Up a Wall
Air Hog Zero G micro car. Think “reverse hovercraft” — a fan inside makes it hug the wall or ceiling.
The car is 6″ long and perhaps 3″ wide, and the shipping weight of the whole thing is 2 lbs, so let’s say that 1 lb is for the car. (sorry, no SI units for this. Imperial units given, and this is just a quick ‘n dirty analysis) So you need somewhere around 0.1 psi of pressure differential generated by the fan to have it “stick” to the ceiling.
Pegging the Geekmeter
Someone with a little time on their hands, feeds some AC/DC into their laser (OK, technically the waveform of the music), and watches the trapped atoms “dance”
The low-pass filtering means it responds more to the bass and drums.
On the Other Hand …
Webcams of the LHC. Very interesting.
