5. I saw that it was so hot that it had to pop. There was a gas inside the test tube when we heated it up.
6. My hypothesis is half right. There is water in the popcorn. When the water gets hot it makes steam. The steam makes the popcorn pop.

ReplyDelete6. My hypothesis was right because I have done it already. If you heat up marshmallows in a small place it will expand. The heated air in the marshmallows makes it expand.
