== Demonstration == ;Preparation: Assemble the Static Electricity Box # Rinse out the plastic platter tray and dry. Stack the small cardboard boxes, strips, or similar until they nearly touch the lid of the tray when inside. Tape them together. # Line the top cardboard box (or cover the top of the stack) with an aluminum foil sheet. Cut two additional sheets to then fold and stack on top, pressing them in and leaving the edge elevated. # Place some of the Aluminum-wrapped styrofoam balls inside the aluminum lined box. Close the lid on top, ensuring it is a snug but sturdy fit. ;Presentation: Style A: # Rub the plastic lid with your cloth (a circular motion work best). Some of the balls inside the box should begin bouncing around and floating. It is also possible to get a couple to stick against the bottom of the lid. # Put your finger tip close to touching the outside of the lid, above where the Styrofoam ball is sticking. The ball will move around! Style B: # Rub the plastic lid with your cloth (A circular motion works best), then place the extra Styrofoam balls wrapped with aluminum foil on top. They will shift around a bit, then stick into place. # Once the Styrofoam balls are in place, bring your finger tip close to one of the balls (or just barely touching it) and the ball should roll and jump around the top of the lid!
