DIY Halloween mini skulls. Melted 3L milk bottle using a heat gun, pressing with a wet sponge over an empty vodka bottle. Tried various techniques such as dry brushing acrylic paint over spray painted base. Takes about 1/2 hr to complete each one. Left one unpainted and put a glow stick inside. Lightweight and waterproof so can be used outside. See pennywise753 for tutorial on technique.
