Review on Zoku Dino Pop Molds: 6 Easy-Release Silicone Popsicle Molds in One Tray - Fun Prehistoric Designs, BPA-Free! by Angie Strongheart

This is the best. They take up more space in the freezer than the old cheap "regular" shapes, but they're a lot of fun to make. We like to just fill them with health juice which kids don't usually drink ;) Freeze then take them all out and store in a gallon ziplock in a regular "not so cold" freezer. Thanks to the silicone mold, they can be easily removed from the floor and easily cleaned with a bottle brush. The sticks are neatly shaped on both sides and have a shape indicator on the grip and shape to ensure you line them up correctly.
