Here's a picture of me with the full Mad Scientist costume in play at a work Halloween party.
The side clasp lab coat with riveted on chemical apron is another story, and one that sadly lacks much photographic evidence.
The next step is to coat the torso in a layer of fake skin. I first tired applying liquid latex to the mold myself, but the foam is like a sponge so to get it to work I first wrapped the torso in plastic wrap.
In latter years I learned to use latex dies to get a flesh tone latex color without resorting to paint.
Two part polyurethane is a fun little chemical. It mixes, and about 20 seconds later it foams up with a great deal of heat. A few hours latter it turns solid. It's also rather nasty stuff. It tends to stick to, or eats away at, all sorts of stuff. Thus the big gloves, as it's famous for merging with skin on contact. It doesn’t smell great either.
