These popsicle molds are the best. I purchased them for my boys and the neighborhood children to make kool-aid popsicles. We purchased two sets to have enough for all the girls and boys to have a summer treat. I'm not much on kitchen gadgets but these ice pop molds work great. First, we spray them with a little Pam before pouring in the kool aid (the tops of the molds lock into the tray). Pam is the magic trick to get them to slide out easily and have perfect popsicles-it does not affect the taste. They are nice, sturdy molds and just the perfect size. They are BPA free and also have a drip tray. My boys favorite popsicle is Watermelon Juice.Recently, we even made some adult summer treats- Bud Light Lemon-Ade Rita-sicles. YUMMERS!
