The Floating Wire Challenge

Challenge criteria: Iron objects sink in water, right? However, this challenge involves using science to make a small piece of iron wire float on water.

Materials needed: Iron wire and a bowl of water.

Challenge tips: Water acts like a stretched membrane, like Saran wrap. The trick is to keep the piece of wire on the water surface for a long time, with some support that can be removed without your intervention. Flatter objects float easily.
