Here is an experiment you can do at home to discover just how sensitive vegetables can be! Ask an adult to help you to make the cabbage juice.
What you need: red cabbage leaves hot water clear vinegar bicarbonate of soda lemon juice
What to do
Put the cabbage leaves in a bowl and pour the hot water over them, stir and leave for a few minutes. This should give you a blue liquid (at least if you are doing this in Norfolk it should, in other places it might be red).
Nowlet's try putting some different stuff into the cabbage juice to see what happens. Try the lemon juice first.
Pour a little lemon juice into the red cabbage juice and give it a shake. What do you think will happen?
