Growing up, my parents always made these cool luminaries when the weather got cold enough. I guess I had forgotten that I could make them too, until just recently.
So I used an ice cream bucket, a sqare tupperware, and a round tupperware (fairly large ones).
I put them out and lit the candles, and have really enjoyed them alot! They're easy to make too.
I filled the containers with water and then left them out on the step for 4 hours one cold evening. Then, take them inside, use a chisel or screwdriver to punch a hole in the top and then dump out the water into the bathtub. You should have a frozen ring with a bottom now. Run some hot water carefully over the outside of the container to loosen the ice, and then pull out the shape and set outside with a candle! :)
