1. Use the pink or blue high density foam insulation or white bead foam. Carve into shapes and lightly glue together with wood glue.
2. Pack pattern into the drag section of the mold. Stack flasks if you need more depth.
3. Flip mold and ram cope. Remove cope and make two 3/4″ sprue holes directly over the pattern. One pouring hole and the other to release stinky gas. DO NOT make the sprue holes with foam, they must be empty when pouring.
4. Pour mold outside! Throw crunchy sand away, reuse moist sand.
