Fizzy Foam! - Why does soda “explode” when you shake it up? (Experiment) |

To see a soda's little bubbles of carbon dioxide at work, try out this experiment!
Pour a little bit of soda into a clear glass, and then set the glass down inside a sink so that if your experiment bubbles over, there won't be any mess.
Add some salt to the glass of soda, and watch what happens! Do you see the way the salt makes the top of the soda get foamy?? This is because the salt attracts the bubbles of carbon dioxide, and then the bubbles all gather near the salt at the top of the glass like fizzy foam! – COOL!
