You can also use the mold to make an ice cream bowl of solid ice, or to freeze a block of juice and fruit to add to a bowl of punch. One mold can make hundreds of lanterns because it is reusable. Instructions included.
It takes up to 24 hours to freeze one lantern in a freezer or outside in below-freezing temperatures, so make sure you get enough molds to make all the lanterns you need in a reasonable amount of time. Mold is 8" high by 6" across the bottom and 7" across the top.
