1) Pie Pan begins neutral: It has an equal number of (+) and (-) charges Styrofoam is charged negatively the whole time

2) Pan is lowered toward the styrofoam

3) The loose electrons in the pie pan will be repelled by the negative charge of the styrofoam and move to the top of the pan Now the pan is polarized

4) A grounded (neutral) hand touches the pie pan, and the electrons repelled by the styrofoam go into the hand

5) After touching the pan, it gets lifted away from the styrofoam. Now the pan is positively charged

When the hand touches the pan again, the electrons return to the positive pan, making it neutral again 6)
