Add skittles and water to a blender. Puree on high until mostly smooth. Pour the mixture onto a large saucepan and bring to a boil. Reduce the heat to low and simmer until the water turns color and the skittles are mostly dissolved. Remove from heat and cool until close to room temperature. Strain the mixture into a measuring cup with a strainer lined with a layer of cheesecloth. Discard solids and cheesecloth. It will be sticky. Pour the mixture into popsicle molds.

Place molds in the freezer and freeze at least 4 hours or overnight.

Remove from popsicle molds and enjoy immediately.
