Squishy Breast Stress Relief Toy

Step 10 Pour the silicone breast

Pour your silicone into the rubber mold so it fills the lowest possible point first, being sure that the rubber rises from the bottom as evenly as possible--like pouring cake batter into a bundt pan. Continue until the mold is evenly filled. Don't worry if a little runs off the sides since it can be trimmed later.

Give your mold a few good hits with something solid (like a paintbrush or screwdriver) to force air bubbles upwards and prevent them from ruining the surface.

Let it sit in a well-ventilated spot for 24 hours to fully harden.
