This effect begins as tiny gelatine-like cubes which expand to normal mini ice cube size after 24 hours in water. They will withstand hot studio lights without melting, and will remain the same after days of use. The cubes will not shrink while placed in water, and after dry storage they will again expand to normal size when put back into water. You can repeat this process as long as you want! Because these magical Condor cubes never melt, they keep their fresh appearence longer than real ice cubes, and therefore a lot easier to photograph. Ideal for still-life pictures and video shooting.
