Here's how to make a plasma lamp in your kitchen. The physics is real cool, but I love his wife's reaction when she comes in!


And this is what you can do with plasma!

The Biggest Secret Rock Concert

Deep within the underground labyrinth of the Luray Caverns, Virginia, USA is what is likely to be the world’s largest and awe inspiring musical instrument: The Great Stalactite Organ. The Luray Caverns were discovered on August 13th 1878 by a group of local men who became the first to see the abundant underground cave formations of stalactites, stalagmites and columns.

The Great Stalactite Organ may be the oldest naturally formed lithophone that has a customized organ console to utilize 37 of the cave formations. Initially, volunteers did performances manually until the concept for the organ was designed and installed in 1956 by Leland W. Sprinkle. Three years were spent finding suitable stalactites to produce the specific note. Each of the selected stalactites was then wired a mallet, creating manual control solenoids, activated by the appropriate organ key on the console.

Pulsar's wobble provides new Einstein test

Einstein can rest easy for a bit longer. Using a pair of orbiting pulsars, astronomers have confirmed a prediction of general relativity about how bodies wobble in the presence of gravity.

But in the future, the unique test will become more precise, potentially revealing deviations from the long-held theory. Pulsars are collapsed stars made mostly of neutrons. Each spins around an axis and shines bright beams of light from its poles. Because the stars are dense and tend to orbit any partners at close distances, strong gravitational fields are at work, making them ideal to test a number of predictions of Einstein's theory of general relativity.

Now, a team has confirmed an old prediction that the warping of space should induce a subtle wiggle in a star's spin. This "spin precession" causes its main axis to trace a circle over time, like a spinning top. "This measurement is the first clear quantitative test of spin precession in a star or a body outside the solar system," says study author Rene Breton of McGill University in Montreal, Canada.

Robot Snakes Generate Power

This is kind of a robot snake in reverse: it's designed to float just beneath the surface of the sea and capture wave energy, which it then turns into electrical power. A science team in the UK has been working on the design, and is now testing small versions in a test tank: ultimately the "real" machines would be 23 feet across and 650 feet long, and be able to generate 1 megawatt. Check out the video to see how "Anaconda" works.

Basically the rubber snakes are moored at the right height to bend as a wave rolls past, generating a bulge in the sea water inside. This gets pushed down the tube by the wave to a generator built into the tail end.

A full-scale device would be able to generate enough power for 1,000 homes, and the developers at the University of Southampton think it may be more resilient than other wave-generators due to its lower moving part count, and the fact that it's made mostly of materials that resist salt-water corrosion.

Plus, it looks satisfyingly sci-fi, in a scary surprise for divers kinda way.

Invasion of the Body Snatchers

Do you remember the insanely great Frozen Grand Central prank? 

Well, Charlie Todd of Improv Everywhere, the guy that did it, replicated this stunt at a suburban Taco Bell Grand Opening. The facial expressions of the unsuspecting lunchtime crowd when 40 performers just froze mid-slurp and mid-bit are pure gold! 
Here are both clips.


and just for grins, here's a copycat event at Trafalgar Square:
