Trent, What a great question! Actually, I just ASSUMED that it would be necessary; my reasoning was that the thin (0.00025 in) plastic coating on each side increases the thickness of the material, _and_ it is translucent. Now you've got me curious. Must make pinhole with unadulterated drink can and see what happens! Gary
