It's time for liftoff, so I pull on my thick, elbow-length rubber gloves and put the fire extinguisher within reach. This is probably overkill, but I'm a little jumpy. I'm not accustomed to unleashing massive amounts of voltage in my cramped apartment. I do one last check of my DC transformer, which I bought online from a guy who specializes in energy systems that are illegal in several states.
He put a sticker on this one: DANGER: ANTIGRAVITY IN DRIVER.
So this is it - my antigravity craft. The device itself is perched on a plastic filing cabinet in my living room. It's an equilateral triangle, 8 inches per side, composed of thin sticks of balsa wood. There's a ring of copper wire from RadioShack strung around the top and a strip of Reynolds Wrap held down with Krazy Glue around the bottom.
When I throw the switch, 20,000 volts will course through this bundle of sticks and foil - and it will levitate. It has no moving parts, no rotors, and no wings. But it will, I've been told, lift itself into the air.
