Wired pubblica una lista delle migliori leggende che si sono create attraverso la fiction di fantascienza. La migliore: esiste o meno un lato oscuro della luna? 🙂
Fiction: If you fall into quicksand, you’ll be sucked under and die.

Fiction: Earth’s rotation causes bathtubs, sinks, and toilets to drain clockwise in the northern hemisphere, counterclockwise in the southern hemisphere.
