How To Make a Breakaway Glass Bottle Prop

Cut a 1'' (2.5 cm) pour hole at the top of the mold in the center. This hole gives you access to the mold cavity for pouring the liquid SMASH! plastic.

Prior to casting SMASH! Plastic into the mold structure, apply Universal Mold Release to the rubber core. This release agent will give the finished SMASH! Plastic a gloss finish. Also spray the inside of the Mold Max 30 mold with Universal Mold Release.

Place the outer Mold Max 30 around the Mold Max 10 core and then use rubber bands to hold the mold together.
