Allow the wax to completely cool. For this step, the more brittle it is, the better. You may even want to chill the cookie sheet in the refrigerator, or outside if it is cool enough. Then flip it over and whack it onto a sheet of newspaper or Kraft paper.

Most of the chunks should come apart. If some are still sticking together, they can be snapped apart by hand.

At this point, you might want to make more chunks... different colors possibly.
