How To Make a Breakaway Prop Bottle Using SMASH Plastic™


In this tutorial video, Milo shows how you can make your own breakaway bottles using Mold Star™ 15 silicone and SMASH™ Breakaway Resin. Milo first makes a silicone mold of a bottle using Mold Star™ 15. After the silicone cures, the bottle is demolded and SMASH™ plastic resin is mixed and poured into the mold. The SMASH™ bottle is allowed to cure, then demolded. As a finishing touch, Milo mists the bottle with denatured alcohol to give it a shiny surface. SMASH! Plastic™ is a liquid plastic designed to shatter/crumble on impact (“breakaway glass”). SMASH! Plastic™ is water clear and, once fully cured, shatters like glass. It can be cast solid in thin sections to make window panes or rotationally cast to form hollow bottles, jars or other glass-like objects to be used as breakable props for movie and stage productions.
