<div>The tests are in my arid southwest home at 5460 above sea level, built</div>

<div>If your scale can handle the ~ 800 grams I would be glad to mail you the aluminum</div>
<div>and copper discs if you provide me with an address.</div>

<div>I don't wish to buy a more sensitive scale since I'm saving up to buy</div>
<div>those hollow copper and steel spheres that McMaster-Carr has</div>

<div>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. :-)</div>

<blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid">Good morning, Fred and all,<br><br>Do you have the original spec sheet for your balance?<br>If so, it might pay to confirm whether there is a
<br>minimum recommended reading resolution to it. You<br>mention that it has a 1 gram resolution, but I infer<br>that is the display.<br><br>Reason I ask is that the weight deltas you are getting<br>are at about 1 gram in this experiment. In the past,
<br>as much as I wince to do so, I generally have to<br>disregard anything at or below the recommended reading<br>resolution of the balance, exception being with my<br>analog lab balance, but even then, anything below the
<br>1mg scale is extremely speculative.<br><br>You may also want to consider the effect of your hand<br>transfering charges to copper and aluminum. Back in<br>2001 or so, I thought I had a weight anisotropy effect<br>where a specially coated glass plate I made looked
<br>like it weighed a couple milligrams more with coating<br>up than with coating down. Yay for gravitational<br>anisotropies! Unfortunately..... Eventually, I found<br>that it had to do with the vinyl gloves I used to keep
<br>everything pristine! Just touching the glass sample<br>with a gloved hand made for an electrophoretic effect.<br>When I went to rubber gloves, the effect vanished.<br><br>But all that aside, where are you performing your
<br>experiment at? Inside a home or lab room; or<br>outdoors? Wouldn't you expect a much greater (less<br>attenuated) effect outside than in? Oleg Jefimenko<br>used to have to find sweet spots outdoors to run his<br>
corona motors off of the earth field, as buildings,<br>grounded flagpoles, wind direction, and even parked<br>vehicles would distort the field profile and gradient.<br><br>N<br><br>--- Frederick Sparber <<a onclick="return top.js.OpenExtLink(window,event,this)" href="mailto:fsparber@gmail.com" target="_blank">
