Yum...a gelatin heart, anatomically correct too...you can also try to make gelatin brains (that when you cut it open, bleeds goo), disembodied hands, and even a Roswell alien! And before you think it would be to hard, all you have to do is pour the gelatin in premade molds...yes Virginia they actually make jello molds like this. And as an FYI, the Roswell alien is an "autopsy" version that has an innards mold. Gross...but that's the point! And before you freak out to much, the recipes for the molds are completely edible (the heart is actually Strawberries and Cream flavored with Strawberry Coulis). Go here to check out recipes and on where to buy the molds.
