Imagine a lollipop that looked like a miniature severed human head.
Once you scrape the scalp skin and hair away with your teeth, you
bite down, facturing the skill. White matter oozes out of the cracks,
and any eyeball pops out of its socket.
Admittedly, this version of a multi-casted lollipop
has a halloween
theme to it, but the methods are the same for any lollipop made this
way.
The innermost parts are molded onto a lollipop stick, and, layer
after layer of different molds, a masterpiece is made. The last
molds create the outer layer of the object. Each layer can have it's
own consistency, whether it be hard (for bone), or oozy (for blood,
brains, mucus or puss), or chewey (for muscles, cartilage).
Halloween: severed heads, carcasses of animals, limbs, insects,
eyeballs, intestines, ears, etc.
