He poured vinegar into a flask (you could use a bottle), added baking soda into a balloon, and then attached the balloon to the top. When he tipped the balloon up, the baking soda spilled into the vinegar and it reacted. The reaction created a gas that filled up the balloon. Wow! Was it ever exciting.
One of the predictions was that the balloon would explode. The kids were pretty nervous as it got bigger and bigger. Good thing Scottie had the goggles on. Even he was scared it might explode!
After the balloon experiment, Scottie did the same thing, but didn't put the balloon on top. We got to watch a volcano erupt! It was fun. Good thing he only brought a small bottle of vinegar, because the kids wanted him to do it over and over, until it was all gone.
Thanks Scottie, (and his mom) for a fun experiment!
