Way Back Whenesday: Duracell Tester Strip

Grandma Conlin always had one of these tester strips in her junk drawer and Madison and I thought it was the neatest thing. Okay, maybe it was just me. Either way, they were neat. They did not however, work nearly as fast as the commercial makes you think. In fact, sometimes they were so slow that you had to hold on to them long enough for them to become very hot.
