COPPER STRIP FOR CRAFTS OR SCIENCE FAIR (1-STRIP)
Okay, it's just a strip of zinc 4" long x 3/4" wide x .027" thick, but CJ says if you take this, a copper strip and a grapefruit to the science fair, you get at least a "C." Copper strips is approx 5" x 1". Great for for assembling voltaic cells, electrolysis experiments, etc. and awfully useful for crafters and jewelry makers, too. Stamped "ZN" or "Cu" toward one end, respectively.
