Barry and Others, Good suggestions. I have always wanted to take a antistatic bag and shake coins, where only the coins were affected, and measure the response perhaps out of the top of the bag. Then put a non-ESD bag with coins inside a antistat bag, making sure in both cases that the coins hit each other in the same way. This series of experiments would isolate the effect of coins hitting coins only. I think Doug Smith talked about these isolation type experiments ar some point in time. How about it somebody who has the equipment? Richard Haynes 609-497-4584
