Empty milk carton (any size desired)
Secure the wick to the bottom of the container with a small piece of soft wax or wick holder. Fill the milk carton with crushed ice. Pour melted wax into the container.
When the wax has cooled, turn the container upside down over a sink and empty as much of the melted water out as possible.
Let the container sit in the sink overnight to drain completely.
Tear away the container.
