Materials Required:
- Saucepan
- Tap water
- Glass
Procedure:
- Fill a saucepan with tap water. Ask one of your parents to boil the water gently for a few minutes. Then leave the pan undisturbed with its cover on until the water is cool.
- Now pour some of the water into a glass and drink it. Does it taste flat and dull? Drink some water fresh from the faucet and compare the taste.
This is what happens:
Tap water contains air in addition to many minerals, and they all help to give water a pleasant, lively quality. But by boiling the water, you have removed most of the air, and this changes the flavour.
