Cupcakes are mostly made of four elements

There must be something about cupcakes and the periodic table of the elements. Not sure who did it first, but now it is ubiquitous. Then of course there is The Periodic Table of Cupcakes, which is a whole other matter. [more inside]

Nitrogen: when good elements go bad

China's Olympic beaches, choked by a plague of green algae. Sez David Suzuki: This is not an unusual occurrence, but it is a symptom of an underlying problem with potential repercussions far more serious than hampering Olympic events. [more inside]

PV=nRT: It's not just a good idea....

200 liters of condensed liquid nitrogen (LN2) were delivered to Berkeley’s Condensed Matter Lab this past Monday. Sent to retrieve the 400lb dewar from the loading dock but faced with a non-working elevator, an enterprising young lab student decided to carry it down the stairs. Gravity is a harsh mistress.

If things had turned out differently, they could have been scraping his remains off the walls with a spatula. At Texas A&M in January a lab was badly damaged when someone ignored the Ideal Gas Law, removed the pressure valve and rupture disk off an old (LN2) tank and filled the remaining holes with metal plugs. "How to Tell a True Lab Story" talks about a similar incident. LN2 is good for more than just blowing up a school (or, um a watermelon), though: Spanish Chef Ferran Adrià uses it to create dishes at his restaurant. Previously on MeFI: How to make LN2 ice cream (careful!) and unwise science experiments.

Just Duct-y.....

Just Duct-y..... Hmmm. Duct tape seems to be a fix for everything, even curing warts. Err...don't try this on the genital kind, I guess.
