Remember MacGyver from the old TV series? He could build a laser from a pair of eyeglasses, a match, and some dental floss and then mount it on a shark, or so it seemed.

We’re not asking you to do that, exactly. Rather, we thought it’d be fun if science enthusiasts like you could explain science with a fixed set of props, just as the Iron Chef has cooks square off to devise creative dishes using a single ingredient.

Building off our video explainer series Instant Egghead, we’re calling this contest Iron Egghead.

Conducted in partnership with SciVee, a leading science-community video site, we want contestants to explain a part, process or system of the human body in two minutes or less. In addition to appearing on camera, contestants must use:

• Paper (or another equivalent writing surface)

• Pen (or other writing implement, such as a pencil or crayon)

• Rubber bands

• Paper clips

• String (or yarn, wire, etc.)

• Cups (eg., paper, styrofoam, ceramic or other type of container)

• Balls (eg., ping-pong ball, tennis ball, basketball)

A panel of judges will declare a winner, whose video will be featured on the Scientific American website along with runners-up. There will also be a viewer’s choice selection.

The contest starts today and remains open to October 31, 2012. We will announce winners in December. You must be 18 or older to enter.
