Gypsnow

Gypsnow is a powdered gypsum plaster that's terrific for faking objects—concrete, cinder blocks, bricks—that are lightweight, fragile, and will be destroyed on camera. The light weight and frailty of cured Gypsnow make it exceptionally safe to break up around talent and crew. Able to be molded into any configuration, once hardened Gypsnow is easy to carve, cut, or shape. It's frequently used to simulate impact effects or to build miniatures that will be smashed, crushed, wrecked, shattered, obliterated, or otherwise demolished on camera. Sold in fifty (50) pound bags. Sometimes referred to as 'pyrosil.' Expansion is roughly 3.5 to 1   NEW FORMULA MIXING INSTRUCTIONS General Notes: Gypsnow expands rapidly with the addition of water. Due to its rapid expansion, the maximum recommended mix for any one pour is five (5) gallons. The following quantities of Gypsnow and water will expand to just over the top of a five (5) gallon pail: 9 lbs Gypsnow + 1.3 gallons water When working with Gyps
