Editing Floating Soap Bubbles (section)

== Demonstration ==

# Set the fish tank on a table, and try to avoid having it in a drafty spot. Measure 1/2 cup of baking soda and spread it across the bottom of the tank.
# Measure 1 cup of vinegar and pour it into the tank across the bottom, and allow them to react. After they finish reacting, you can start blowing bubbles!
# When you blow a bubble, blow it '''above''' the tank and let it descend into it. Do NOT blow the bubbles into the tank, or you will blow the gas out of the tank!
# The bubbles will float on the gas that was released during the reaction inside the tank, making them seem to float in midair! 
# When they stop floating as well, or if the tank gets air blown directly into it, you will likely have to add more baking soda and vinegar to continue the demonstration. When finished with this demonstration, be sure to rinse out the fish tank, and let it air-dry once you return.
