Fun with water experiment.

Last week we did a water experiment about how water works. Then we got a needle to try see if it could float if we had put it on top of a cup of water it was very hard for it to make it float. Here is one of the photos. There was another experiment. So we got a piece of paper and put arrows on a direction going to the right but when we put behind the glass of water it goes the opposite direction.But unfortunately there was no photo of it.
