I don't have the PC ones but popsicle molds are always a hit with kids!

I have some pop molds similar to these and it's so great to put fresh juice and thinly sliced fruit then freeze.

These molds are so fun to use and super easy to clean. You can basically make any frozen pop mix you want. You add it to the mold, freeze, remove from the mold and serve your family healthy pops with no preservatives. I like that there is a built-in catch at the base of the handle that catches drips. Genius! I love to make strawberry, raspberry or blueberry pops but we always blend fruits to make new recipes every time. Great activity to do with your kids.
