<p>[QUOTE=&quot;-jeffB, post: 1073806, member: 27832&quot;]As late as the 1960&#039;s, textbooks and &quot;science magic&quot; books described how to turn a penny silver by rubbing it with mercury. If your grandmother had this for decades, it&#039;s quite possible that it&#039;s a TERRIBLE ENVIRONMENTAL HAZARD THAT WILL TURN YOUR CHILDREN INTO TWELVE-EYED MUTANTS. (Or sit there, stable, as it has for the last forty-odd years.)</p><p><br /></p><p>Sorry, I get a bit peeved at mercury hysteria. It&#039;s good that we&#039;ve reduced its use and waste, but it&#039;s not plutonium.[/QUOTE]</p><p><br /></p>
