Resin cast of human heart blood vessels. This model was achieved by injecting liquid plastic into a real heart. The plastic resin fills the blood vessels and, once the resin sets, the tissue is dissolved away leaving a perfect replica of the blood supply.
OUAT cast. I love them! Seriously, the relationships that the cast of OUAT have really make me want to be part of a TV series cast so I can have an awesome relationship like them. Plus they have so much fun, what an awesome job!
