More Sensational Science in HG!

In HG this week, we made a Bubbling Wizard’s Brew! We half filled a glass jar with clear vinegar. We added several drops of green food dye and a little glitter for effect! We added a good squeeze of washing-up liquid to the jar and gave it a gentle stir. Then for the exciting bit – we added a heaped teaspoon of bicarbonate of soda and watched the ‘chemical reaction’!

We found out that when the vinegar and bicarbonate of soda mix, they make lots of tiny bubbles of gas. The bubbles churn up the washing-up liquid, making lots of foam.
