Hello. I have a question. I have two glasses - one is full, one is empty. And I will take a long paper towel to them - the first end to full glass and the second end to empty glass to same height. A paper towel is absorbent. Water from full glass rises to empty glass. It will stop when the hight of watter will be in glasses same, yeah? However, can you tell me why?

Pls, explain me it, i really want to understant it.
