Floating Metal

Fishbowl with aluminum floating
PIRA: 2A10.20

Materials: Paper Clip, Tin Foil, Fish Tank, Water, Soap (If Necessary)

This demo is to show that the surface tension of water and if things are filled with enough air then they will float on water. This is done by carefully placing the paper clip on the surface of water. The paper clip should float if not using soap can help the surface tension hold the paper clip better. The other metal floating can be the tin foil boat that was made. This can show that when something is filled with air it will float because air is less dense than water.
