I stumbled on this the other day when I was surfing the net. A few students have asked what they could do to stop the copper foil from rolling and bunching up into a large mess when they are foiling their glass. Well, besides a copper foil holder here is an interesting thing you can do at home. A foil can, LOL. Looks a little strange, but I’m sure it works and if you use something like caned peaches if you get hungry just make sure you have a can opener and a fork in your tool kit and you can take a break and eat.
