I'm Raquel Aguado and I'm going to do an experiment of obtaining clean water from dirty water.

2
00:00:11,800 --> 00:00:36,640
For this experiment we need a cord, two glasses, one with dirty water and the other without water, and a box.

3
00:00:36,640 --> 00:00:47,200
two glasses and we put it into a flat surface. Then we take the box and we

4
00:00:47,200 --> 00:00:57,100
put one of the glasses with the other two water there and the other here and now we take

5
00:00:57,100 --> 00:01:33,459
the cord and we put it here and here like this. Here we have the result, we have

6
00:01:33,459 --> 00:01:40,379
here the water and here the clean water. Why does it happen? It happened

7
00:01:40,379 --> 00:01:45,140
because of the water's capillarity. It allows that our sentence go up into the

8
00:01:45,140 --> 00:01:50,079
cord but no dirt. That's why we have clean water and that's the end of my

9
00:01:50,079 --> 00:01:54,719
experiments. I hope you like it.
