As you know, helium (He on the periodic table of the elements) has many fine uses, such as: filling up your birthday balloons, making your voice higher, and creating totally pristine treble on your $4200 Plasmatronics speakers (available right now on eBay). Sure, you could just keep on using the stuff for celebrations or hilarious gags, but wouldn't it be more of a gas to drop four-large on a pair of these 1970's behemoths? "Buy it now" before your chance to own a piece of helium-powered audiophile history passes you by.
