Fill one of the glasses with water, stand it next to the empty glass and lay the paper into them, as shown in the picture. 3.Leave the glasses and check them a day later What happened? Some of the water — as much as half of the water if your siphon works well — will have moved from the full glassto the empty glass. Water is made up of tiny particles (粒子), and a piece of paper contains tiny spaces between the paper fibers (纤维)that hold onto water particles. Those tiny spaces pull water along with a force called “capillary action (毛细管作用)”. In your siphon, they pulled the water particles over into the empty glass. 31.
