    LED Throwies

    Letting the "wrong" LED lead touch the battery won't cause a short or damage either component. LEDs are diodes and only function one way round. It won't harm the LED to be reverse-biased, and indeed it's designed to be connected this way in larger circuits. Lithium batteries shouldn't present a disposal hazard when used in this way, as they'll be fully discharged when they do reach landfill.Better than chucking them once they've run down, why not "catch" them with a stick/net/string, and re-build them with a new battery?

    Build a Soundproof Wall

    Egg cartons, carpet on the ceiling, felt wallpaper etc is not an attempt to soundproof as such, but to improve the acoustics of the room, typically reducing echo.
