Greatly to Doug's and my joy and in no small part surprise, the red dark jello flowed nearly to the bottom of the void that the copper form had left. Yay! Doug's inspecting our creation here. It has a very "tissue-y" appearance close up -- quite disturbing. You can also see what's becoming of the gummi bears we added earlier: they're dissolving. D'oh!
I also shot some video of the filling process.
