Mercury, the sweetest of the transition metals!

Mercury is such a dense liquid that cannonballs float in it. Humans float on it too (you'll have to scroll down a bit for the picture), but it's probably not a good idea. If you just can't resist hopping in the mercury vat, elemental mercury is less likely to kill you than mercury compounds. It used to be sold as a laxative (officially branded Dr. Rush's Bilious Pills but colloquially known as "thunder clappers"); Lewis and Clark's campsites can sometimes be identified by the mercury they deposited along the way.

Welcome to San Francisco. Now what the hell are you doing here?

San Francisco can become a world capital. First it needs to get over itself.

I think the Texas idea is a good one

Online Unit Converter

UnitConversion.org is quite the resource to easily convert between different units of measurement. It has over 2100 units in 78 categories, which range from those that are common, such as, length, weight, volume, currency, velocity, and pressure, to more specialized categories like magnetic flux density, electrostatic capacitance, and surface tension.

Grand Theft Delorean

Back To The Future, Hill Valley is a "from the ground up" conversion of the videogame Grand Theft Auto: Vice City, with the goal being to re-set the game in the world of Doc Brown, Marty McFly & Biff Tannen. Sample videos of the progress so far. Please note that Hoverboards don't work on water. Via.

For sale. Baby shoes. Never worn.

2 4 8 16 32 64... Storybytes, an ordered archive of nanofiction. It's been done before, by syllables (17), by the masters (Classic Short Stories), and by comedians (Book-a-Minute). But in a dense natural language, with a high meaning-per-word, perhaps bytes would value infodensity more objectively: 256b, 1k, 4Kb. But then again, isn't a spec as much of a cop out as a rigged dictionary? Perhaps the highest infodensities are achieved by works which will have no human readers.
