use food dye to make ice cubes. Then put them in a glass of water-voile. Would be good for a party. Rainbow ice water - Taste the rainbow! - this would be cool for Christmas drinks. Red, green and edible glitter!
Everything rainbow! I made these by hand! just remove the original white paste from an oreo. Whip it up with the food coloring of your choice of you choice and put back in the oreo! And they make the most perfect party treats!
