Ryan's Science Experiment

Ryan decided to be a scientist and have a go at an experiment that he had never tried before. It was to make a bubbling witches brew! He needed vinegar, glitter, dish washing liquid, food colouring, and baking soda.

Look what happened when he combined the ingredients together! Lots of Kohara gathered around to watch. We predicted what might happen and then waited. It was a bit slow to start so we added more vinegar and more baking soda. 

We wondered what made the bubbles appear? What do you think?

Can you think of another experiment that is similar to this? Clue: Lava.
