Water is all around us
D says: Water IS all around us. To experiment, we put ice cubes and water in a glass. Then we waited for 10 minutes and when we came back there were little water droplets on the outside of the glass. So what happened? Since there are water molecules in the air that are always bumping into things (I think they are clumsy), they hit the side of the glass, cooled down and stuck to it. Then they condensed from gas into water. This experiment was kind of boring compared to making polymer goo and pretending it was a giant booger, but I did learn something new.
