Demonstrations

Identifier Title Demo Summary
FL: ST - 002 Drops on a Penny
FL: ST - 003 Cup and Cover

A glass of water is covered by a piece of plastic and overturned, resulting in the lid staying attached to the glass.

FL: ST - 005 Floating Paper Clips

Paper clips are floated on a body of water.  When soapy water is added, the paper clips sink move away from the soap and sink to the bottom.

Supplies for the demo are: a container of water, several small paperclips, a tool made from a larger paperclips, a small container of soapy water, and an eyedropper.
