We made a couple of bubbly chemical reactions today. Jr. scientist A's prediction: "It's gonna be messy." For our first reaction, we mixed hydrogen peroxide and active dry yeast. This made big bubbles (left picture) that raised up in a high column before the column eventually fell over. For our second reaction, we mixed baking soda and vinegar and got much smaller bubbles that quickly ran over the edge of the container (right picture). Jr. scientist A. liked these experiments a lot.
