Science (Tell-Tale Tea)

Materials:

2 tea bags
1 plastic jug
Boiling water
3 clear tea cups or glasses
Bleach
Household cleaning liquid

Let’s Do It:

Place the tea bags into the tea of and add about four cups of boiling water. Wait for the water to become tea.
Arrange the 3 clear cups or glasses next to each other and pour an equal amount of tea into each one. Check that the level is the same in each cup.
Add a few drops of bleach into cup A.
Add a few drops of household cleaning liquid into cup B.
Do not add anything into cup C.
Have a close look at the colour of the tea and compare the colour in each cup.

Why it Works:

We added Bleach into cup A which made it go darker.
We added household cleaning liquid into cup B which made it stay the same.
We put nothing into cup C so it stayed the same.
We put vinegar into cup D and that made it lighter.
