Hershey's Kisses

Approximate size: 60mm x 60mm

Foldability:
If you can get the foil wrapper off of a Hershey's Kiss in one piece (no mean feat), it is a near perfect square. Too bad the foil is so thin and delicate as to be almost impossible to fold without tearing. It takes great care and a little luck to produce even the simplest model. I have found this to be true of most foil-wrapped chocolates (Dove chocolates, Reese's miniature cups and the like).

Coolness:
For all the work it takes to fold a Hershey's Kiss wrapper, the reward is meager. The resulting model could have been folded from any old crumpled piece of foil. Sure, Kisses come in a variety of nice colors, but no one is going to look at your handiwork and say, "Isn't that a Hershey's Kiss wrapper?" Uncool.

Edibility:
One bite of plain chocolate. Zzzzz. Personally, I prefer the waxier chocolate in Hershey's chocolate bars. Recent innovations like caramel and mint filling have added some interest to the kiss genre, but this remains a pretty ordinary candy.
