[NewCandle] Aluminum and Copper Disc Weight Effects

[Frederick Sparber]

More questions than answers, Nick.

The tests are in my arid southwest home at 5460 above sea level, built
on a concrete slab floor with carpeting and enough static electricty and EM
noise around to
light up Cleveland.
If your scale can handle the ~ 800 grams I would be glad to mail you the
aluminum
and copper discs if you provide me with an address.
my email *fsparber at gmail.com* <fsparber at gmail.com>
I don't wish to buy a more sensitive scale since I'm saving up to buy
those hollow copper and steel spheres that McMaster-Carr has
on their website *http://www.mcmaster.com/* <http://www.mcmaster.com/>

Copper toilet bowl floats with 1/4-20 thread fitting, and brass rods are
cheaper, but I can't find any that are aluminum or stainless steel.   :-)
