What do you think would happen if you mix baking soda, dishwashing liquid and food colouring in a tall glass and then add vinegar!??
Can you remember which ingredient is the acid and which is the carbonate?
Some more things to think about:
What effect does the dishwashing liquid have on this experiment?
Does the shape and size of the glass effect the experiment?
What is the name of the gas that is made by mixing an acid and a carbonate?
To watch another cool fizzing experiment take a look at this great clip Mrs. Chao found!!

Dylan says "I learnt how to make witches brew, and I want to try it at home. To make it you need dishwashing liquid and food colouring and vinegar and baking soda and a glass." "That sounds cool", says Mum.
Carmen here! Amalia told me all about the fizz inflater experiment and she loved it! I wish we were shown cool experiments like that when I was at school! Well done!
I really liked doing the Fizz Inflater. Nina and I tried it at home. There was a hole in the balloon at home. The fizz went up into the balloon and squirted out the hole.

I loved doing the science experiments. My favourite one was the fizz inflator, I showed my family how to do it when I got home.
My little sister took the idea to her Barnados as well.
