Styrofoam is charged negatively the whole time

1
1)
Pie Pan begins neutral It has an equal number of
() and (-) charges
Styrofoam is charged negatively the whole time
2
2)
Pan is lowered toward the styrofoam
3
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
4)
A grounded (neutral) hand touches the pie pan,
and the electrons repelled by the styrofoam go
into the hand
5
5)
After touching the pan, it gets lifted away from
the styrofoam.
Now the pan is positively charged
6
When the hand touches the pan again, the
electrons return to the positive pan, making it
neutral again
