The kids and I found some gel ice cubes that look like fish...they thot they were sooo cool and wanted to see how they worked so we brought them home washed them and placed them in the freezer for 30 minutes and voila put them in their drink to chill it and they just loved watching "the fish" in there...I took a few pics! I had never heard of these till about 8 years ago but they work well as they don't dilute your beverage. Sure makes the kids want to drink more water...
