Okay, there's a lot of potential trademark infringement going on in this Instructable, but the author (SFHandyman) actually does a lot better job than I did in obscuring the trademarks. The short of it is that this Instructable contains two important pieces of information:

1. How to make a food-grade silicon mould;
2. How to make gummy candies, the kind that are often in bear-shapes.

The shape that they're using is a kind of brickish, lego-y… oh, he uses LEGO bricks to form his mould. In any case, either part of this instructable is something to have in your bag of tricks, and both makes it required reading.
