Water can run away in interesting ways. Let's try to get water from one cup into another.
What you need | ·An empty glass ·A glass with blue water ·A glass with red water ·Some paper towels |
What you do | Step 1 Prepare "paper bridges". Use paper towels to make two of them. They will take in and carry away water. |
Step 2 Take one paper towel. Put one end of it into the glass of blue water and the other end into the empty glass. Take the other paper towel and do the same thing to the glass of red water and the empty glass. | |
Step3 Watch what is going on. Be patient! The progress of the experiment goes slowly. | |
What you see |
Interestingly, if red and blue go together, it becomes purple. So, you will see three colors now. The empty glass keeps getting water. In the end, there will be the same quantity of water in each glass. |
What you learn | When the paper towels touch water, there is a kind of power between water and the towel, so water goes to the paper towel and then run away. ▲. For example, water travels from the roots to the rest of the tree. |
Your paper towels start getting wet and after some time you will find that the empty glass is starting to have water, just like the picture（→）shows.
