What Is It?

26 What Is It? You can see it, but you cant hold it. It can be hot or cold. You can only live two or three days without it. Can you guess what it is? It's water! We all need water. We need water to drink. We need water to cook. We need water to take a shower. We need water to grow trees, plants, and vegetables. One person uses almost 135 litres of water every day. Wow!

Now, you're happy.
