Dnacing With Salt - Mack and Adam

The Styrofoam which is the isulator was charged by friction while the pie tin which is the conductor was not. This is why the salt sticks to the styrofoam and bounces off the
pie tin. When salt gets charged, the neutral object gets the same type of charge as the charged object that touched it. The salt bounces up and down between the pie tin and the table because some electrons were moving from one to another. We used foam and rubbed it with animal fur. As soon as we put it on the salt the electrons moved from the table which contained less electrons than to the foamwhich had more electrons that caused the salt to sick.
