[NewCandle] Another observation for Fred.

[Keith Nagel]

I put the scale on a 9V battery, and went into the
kitchen for the cold water pipe. I used a thin strip
of aluminum foil to get from the metal pan to the
tabletop, and then from there a wire to the pipe.

Taking the Teflon slab in hand I grabbed the cat and powered
up. There was crackling, and the cat donated a few
more of his infinite supply of electrons. He's
really good at this, so it seems. 

With the pan grounded ( either to the table top or
cold water pipe, made no difference ) I measured no
weight difference between the Teflon charged or
uncharged to .1 grams. The slab is 116 grams.

With the pan free to float electrically, I would
see a ~1 gram increase in weight due to charging.
Over time that would drop as the uncompensated charges
on the Teflon were slowly neutralized.

My question to Fred is, why don't I see a repulsion
from the grounded pan?
