op creators of any age can make their own astro-treats. Add your favorite juice, yogurt, pudding, or smoothie to the mold. You could even use melted chocolate to make your own chocolate pops. With your ingredients in the mold, add the sticks with built-in drip guards, and place the mold base gently in your freezer. Once your pops are frozen (approximately 8 hours or overnight), it’s time to for takeoff! Gently pull on the astronaut stick feet and the silicone mold will automatically invert with a POP—no rinsing required. The pop is released so easily, even the smallest astronauts will say "Houston, we have no problems." For the rockets, pull the stick out of the base to remove the individual mold along with the pop. Run the mold under warm water for about 30–60 seconds to release the ice pop. When it’s time to clean up, use mild soap and water. And like all Zoku products, they're BPA and phthalate free.
