Another video, reminiscent of the viral popcorn-popped-with-a-cellphone video I discussed a while back

I was decreasing the local entropy in a small part of my abode and found a shoebox full of photos which happened to contain a few shots of my grad school lab, in all its glory. We were building an interferometer which would use cold atoms, which means relatively large deBroglie wavelengths and a [...]

This has it all. A scientist, working on his own, discovering something new (and useful) using proper scientific methodology … and he’s in high school. WCI student isolates microbe that lunches on plastic bags
First, he ground plastic bags into a powder. Next, he used ordinary household chemicals, yeast and tap water to create [...]

Is coming from sciencegeekgirl’s Hands on Science Sunday: Feeling pressured?
All you need is a big trash bag and an industrial strength vacuum cleaner, and a willing victim (er, “faithful subject of science.”) The victim (aka “subject) gets inside the bag, and once you suck all the air out of the bag with the vacuum cleaner, [...]

Extreme Ultraviolet Laser Challenges Einstein
No, not really. (Any headline that implies that Einstein might be wrong is invariably incorrect — these are things that have been tested for 100 years)
In the new study, the physicists shot xenon atoms with FLASH, an x-ray laser that uses intense photons in the extreme ultraviolet energy range, [...]

Nobody can see the one at the end of the line, and (s)he’s doing something different.
Nanophysicists find unexpected magnetic effect
In new research appearing this week in the journal Nature, physicists at Spain’s University of Alicante and at Rice University in Houston have found that single-atom contacts made of ferromagnetic metals like iron, cobalt and nickel [...]

Those who divide the people in the world into two types, and those who don’t.
Or, you can divide experiments up by classifying them as edible or inedible: Edible/Inedible Experiments Archive

The PRL from the ArXiv paper I linked to in Follow the Bouncing Atom has been published.
Phys Rev Focus has a story on it

17 cool magnet tricks
I’ve done several of these, including a version of the homopolar motor. The eddy current damping is fun, too — you can make nonmagnetic metals react to magnets by inducing current flow in them. Lenz’s law.

Atmospheric pressure is about 10 N/cm^2, but there are a whole lot of square centimeters on that tanker — the more familiar unit is N/m^2 (Pascals), where 1 atmosphere is 101325 Pa (or possibly even more familiar 14.7 psi).
Various sites showing this have claims [...]

Constructing a bacon-plasma torch which can cut through steel. Ok, thin steel, but geez!
Bacon: the Other White Heat
And, to balance the diet,
A cucumber makes an even better edible thermal-lance housing, since its outer rind contains the pressure of the very hot flame without burning up
