<p>[QUOTE=&quot;-jeffB, post: 1489451, member: 27832&quot;]I agree that the reactants inside the box diffuse throughout its space, and that they&#039;ll react with whatever metal is available. However, the <i>surface area</i> of the Intercept Shield material is presumably much greater than that of either the coins you&#039;re protecting or the coins you&#039;re sacrificing. So the IS box should grab up the reactants more quickly than your coins will, offering better protection.</p><p><br /></p><p>How much of a difference is there, really?
