Tissue Paper Hot Air Balloon
Perhaps you've seen hot air balloons for sale as science demonstrations/experiments that you fill up with hot air from a hair dryer and let float to the top of the room. This product can be easily recreated on a smaller scale with tissue paper. This project is a great way to demonstrate and learn about gases and density. You'll need: 5-6 sheets of tissue paper, a strip of paper, a glue stick, a marker, scissors, and a hair dryer. The first step is to layer 5-6 sheets of tissue paper and fold them in half lengthwise. Use a marker to draw a half tear drop shape. Cut along the line and unfold the layers. Each one will be a panel for the hot air balloon. Using a glue stick, or wet glue thinly applied with a paintbrush, glue one edge (marked in the picture above) and layer another panel on top. Pres down firmly to seal the edge. Once the glue has dried, unfold the two panels to inspect for any holes. Make sure to seal up any gaps.
