QB Kraftz Baby Aliens is patented and allows you to stack them as high as your freezer allows. Make as much ice as you want.
The outer housing is insulation that allows the inner molds to cool slowly. QB Kraftz Baby Aliens has a special valve at the bottom that allows water to push from the bottom as it freezes, creating a crystal-clear slow freeze on the ice in the mold and at the same time, keeping its shape.
The water at the bottom settles in a special small ice tray for regular cocktails or blended drinks.
