<p>[QUOTE=&quot;Just Carl, post: 556344, member: 4552&quot;]If you use a six sided pensil for the balance beam instead of the round plastic roll, it would stand still a little better. Then you place a drop of rubber cement glue at the balance point of the popsicle stick. Of course you could reverse the process by placing a Zinc-Copper coated one at the far end of the stick. Then any all Copper ones would make that side drop fast. If a Zinc-Copper plated one was put on the other side it would only balance. Also, if you use a drop of rubber cement to hold the permanent coin in position your scale would be more permanent and the coin on the permanent end would not move. Also, note any popsicle or ice creame bar stick would work for this system but remember to eat the ice creame first. :eat:[/QUOTE]</p><p><br /></p>
