The fake blood makeup is actually the exact same recipe as the gummy heart. To get the right look, I smeared some around my mouth and let it drip off my chin and onto my chest, and then took a big handful in both hands and let it drip down my arms. And then stood over the hotel room sink and let it drip. It took about 15 minutes to dry, maybe half an hour to really cure, but once it did the drips were all completely solid and not at all sticky -- kind of the dry, powdery texture of gummy bears. That meant that I could open doors, push elevator buttons, pose next to other people, etc, without leaving any fake blood behind. The drips still looked wet, but were in fact completely solid.
