Chemistry

For since i did marbles in a jar. I also did dye in a jar. The dye is already starting to dissipate. We put some rice in a jar and a marble. Then we shook the jar and the marble came to the top. We putt a nickle on it side and balanced a toothpick on it. Then we put a cup over it. Then we rubbed a balloon on are hair and put it next to the cup. When i did that the toothpick moved.
