Ideas for my VIDEO

In a few of my classes I've watched a video of the same experiment. The concept for this experiment is Piaget's theory of conservation. This is commonly demonstrated by two beakers of water, same size and shape, and same amount of water. An adult asks a child (around age 4) which one has more water. They answer, "they have the same." Then the adult pours one beaker of water into another beaker, taller and skinnier. When asked which has more, the child thinks the taller beaker has more water. Thus showing their inability to conserve. There's a few more mini experiments that show this too. All the videos I've seen are pretty outdated so I thought it would be nice to remake the video and modernize it. I'm going to use my little sister to videotape the experiment. I'll do the beaker experiment and one more involving pennies. Then I'll use iMovie to edit the content and make it professional- hopefully.
