Okay, technically this isn’t a lava lamp, but you could have fooled me, given the mellow music and the drifting plumes of colored liquid. Researchers at Cambridge performed an experiment to find out more about fluid dynamics by coming up with two completely different ways that liquids can mix due to Rayleigh-Taylor instability, along with a video to watch if/when you’re stoned.

In the 1960s, when some were exploring the mysteries of outer space and quantum mechanics, one engineer noticed an extraordinary unexplained phenomenon in shampoo. The sudden, energetic, and seemingly spontaneous bursts of liquid that seemed to randomly squirt out from ordinary shampoo were a mystery for forty years. Here’s why your shampoo, while being poured, sometimes leaps up and tries to get you. More »

Ever notice a dirty lotus leaf? How about a wet one? Of course you haven’t. Lotus leaves are so hydrophobic that they can be dry in a rainstorm, while still using the rainstorm to clean themselves off. Now nanotechnology developers are trying to mimic the Lotus Effect. More »

Elon Musk, the founder and CEO of the private spaceflight company SpaceX, has announced an ambitious plan to colonize Mars by shuttling 80,000 pioneers to the Red Planet at a cost of $500,000 a trip. The first phase of the program, which is contingent on the development of reusable rocket that can take off and land vertically, would start off modestly with only a handful of explorers leaving Earth at a time. But in short order, the self-sustaining population could grow into something far greater. More »

Stents have long been used in medicine for keeping blocked arteries open, along with various other tubes of the body that are prone to blockage and collapse. Now, this same concept has been shrunk down to a minute size, and might soon be finding a home in your eyeballs. More »

Romans may have used 20-Sided die almost two millennia before D&D , but people in ancient Egypt were casting icosahedra even earlier. Pictured above is a twenty-faced die dating from somewhere between 304 and 30 B.C., a timespan also known as Egypt’s Ptolemaic Period . More »
