Coke

When I added the salt into the coke I saw the salt quickly fall into the coke bottle and in a matter of seconds the

coke started to froth up which then made the coke over flow into the balloon. Then I saw the coke full about 1/3 of the balloon and I saw the coke inside the balloon slowly

pour back into the bottle leaving me a medium sized balloon.

I really liked conducting this experiment but I wonder what other variables would make the

same sort of reaction.
