Hello everybody, I'd like you to meet my next purchase: Alphabet Ice Cube Trays. My son loves ice and he's learning his letters. How much fun could we have with these? The possibilities are actually pretty endless, and most have little to do with making a refreshing drink on a hot day. I I think I might use food coloring to color the letters/numbers and use them in a bath or outside. The molds are made of silicone, and are therefore heat-safe, so I could make little alphabet "cupcakes" or muffins, too! If I'm feeling patient one day, he could use these as play-doh molds (homemade or store-bought). These things are pretty great.
