- Bubble blowing wand
- Empty bucket
- Measuring cup
- Baking soda
- Vinegar
- Newspaper

Process Floating Bubbles Experiment :
1. Find a good place inside with no draft. Lay down some newspaper for any mess.
2. Measure out 1/2 cup baking soda and dump in bucket.
3. Add 1 full cup of vinegar to the bucket. Watch as the chemical reaction starts to fizz and produce
carbon dioxide gas.
4. As the fizzing begins to stop, start gently blowing bubbles up into the air above the bucket. You
want the bubbles to float down into the bucket on their own. Do not blow them down directly into the
bucket - it wont work.
5. What happens to the bubbles that float down into the bucket? Thats right! They magically float or
levitate in mid air. Pretty cool to watch!
6. Eventually the bubbles will settle to the bottom or smash into the side and pop. Dump the
contents of the bucket and repeat steps 1-4 to do it again.
The Science Behind The Floating Bubbles Experiment:
The bubbles are levitating on top of a chemical reaction.
We have mixed and acid (vinegar) and a base (baking soda). The reaction produces carbon dioxide
gas which settles above the liquid in the bottom of the bucket in an invisible layer. Acids have
hydrogen particles inside of them, and bases have hydroxide particles inside of them. Mixing acids
and bases generates the acid and base reaction that fuses hydrogens and hydroxides.
The base (baking soda) has carbonate inside of it (baking soda is known scientifically as sodium
bicarbonate.) The chemical reaction produces carbon dioxide gas. The gas is being produced
when you see the fizzing in the bucket. But its invisible!
When you blew through the bubble wand to make the bubbles, the air you blew contained oxygen
and carbon dioxide. This means the bubbles contained a oxygen / carbon dioxide gas mix that was
lighter than the pure carbon dioxide gas produced from chemical reaction in the bottom of the
bucket. The carbon dioxide gas produced by the reaction was heavier than air, so it stayed in the
bottom of the bucket. The bubbles we floated down into the bucket stopped falling and levitated
because they were floating on a layer of carbon dioxide gas generated from the acid and base
chemical reaction! Now go do the floating bubbles experiment with some friends.

In this experiment will make bubbles that float on top of a chemical reaction! These floating bubbles
are magically suspended in mid air by carbon dioxide gas.
