My sister's science teacher showed them this experiment. First the teacher put a certain amout of water that went in to this tube and into a box (not a cardbord) that didn't have any electronic device, it was just a regular box. Then it went out of the box (from the tube) and was put back into the jar. When they looked at it, it had more water than before!! Her teacher said that she won't tell them until they become a science teacher (and I know my sister is not going to become one!)! My siste and I are dying to know the secret! Can anyone tell me??
