Making a shot glass out of ice is a cinch. I actually used two flavors of a Kool-aid-like beverage to make these glasses; blue raspberry and blueberry pomegranate. Not only do they make the ice shot glasses a lovely shade of blue, they taste good too. However, they do leave a bit of residual stickiness on your hands. If you don’t want your hands to get sticky, but you still want color, simply add a bit of food coloring to the water.
