When I lived in Troy, wrought-iron was as common as a cold. In the 19th century there was a major foundry there, and I just love the look of wrought-iron. I never thought that I'd see a car made out of it.
lothie reminded me that I have a mac, sitting in a closet that should be reconnected at some point.
Last, but most definitely not least- we've all seen Mr. Wizard. We've probably done the potato-battery thing at least once, right? At least seen it on TV. Well how much power do you get out of a potato battery? Not much. But, when you use five hundred pounds of them and drive it around in a uhaul you can power a stereo. Though I have to say, 500lbs of potatos don't look like much.
