[NewCandle] Aluminum and Copper Disc Weight Effects

[Frederick Sparber]

The 3 inch diameter x 1 inch thick 319 gram (consistent) Aluminum disc and
the 2.5 inch diameter x 1/2 inch thick 376 and 377 gram (depending) Copper
disc from McMaster-Carr were weighed on the 10 kg 1.0 gram resolution
Acculab digital scale combined (stacked) and separately

The stacked weight would vary between 695 and 696 grams depending
on removing and flipping the stack or copper disc over.

The lower work function Aluminum is supposed to charge positive
upon separation from the higher work function copper when they
are separated from contact.
