Since we have been talking about colours this week, I thought this fizzy colours experiment was perfect.
You will need:
an eye dropper or syringe
Add vinegar to the cups and add a few drops of food colouring to each one.
Put a layer of baking soda on a flat dish.
Use the syringe or eye dropper to pick up some of the colour and drop it on the baking soda.
See what happens.
Experiment with different colours.
The children wanted to do it again and again.
