Why do balloons expand when you put soap in them and then in the microwave?
Question Date: 2008-09-08
Answer 1:

If you put soap in a balloon, and then put it in a microwave, the heat will cause the liquid water in the soap to turn into a gas. Since a gas takes up much more space than a liquid, the balloon will expand.

Answer 2:

I don't know what soap does in the microwave, but I will bet that it expands. In that case, yes, so will the balloon (unless the balloon bursts...)
