Revise 5 is a color changing pack of gum where not only the front of the pack changes colors, but the gum inside changes along with it. In fact, FIVE great changes occur! (1) The front of the package turns from blue to red. (2) The blue gum turns into red gum. (3) The front turns from red to green. Still with me? CRAZY!! (4) The red gum turns to green gum. AND (5) If that’s not enough, the green gum VANISHES!
