Chemical Popgun

There is a big mess on the ceiling in Room 1.
We put vinegar and baking soda in a small plastic bottle and quickly put a cork in the top of the bottle. There was a chemical reaction and and the resulting carbon dioxide gas blew the cork and fizzy, bubbly mixture up very high onto our ceiling. It dripped down and made a mess on the white ceiling.
The mixture exploded! It was lots of fun.

Making Sherbet


It was real yummy and fizzy in our mouths!
We made sherbet using icing sugar, raro crystals, baking soda, citric acid and tartaric acid. When all the ingredients were mixed together we looked at and tasted each of them and some were yummy and others were yucky. The fluid in our mouths mixed with the sherbet and made the carbon dioxide bubbles.
