Do you actually have friends? I haven't used the tester of Alumilite that I bought, but here is what I do know. Neoprene casting, like Latex casting, works through absorption. They are poured into a porous molds (Plaster, or other gypsum cement), and the water from the liquid is absorbed into the walls of the mold. The liquid then forms a skin on the inside of the mold. After a period of time, one pours the excess out of the mold, leaving a hollow casting. Alumilite does not work by absorption, it is a resin, and will catalyze (chemically cure, not air dry) as a solid mass. That is generally too heavy for puppeteer's uses. Two ways to get around this are to build a core mold, which can be very tricky to remove, or to spin your mold so that centrifugal keeps the material on the skin of the mold, leaving a hollow center.
