Rinse the inside of the glove well and fill with the beet juice. Add water if needed to make the properly sized hand.
Make a knot in the top of the glove, or tie shut with a rubber band. Freeze for several hours or overnight, until frozen solid.
Run under hot water for a second or two and then peel the glove from the hand. Put in the center of your witches brew. This serves four, so there are plenty of chilly fingers to go around.
This is cool served in a punch bowl with the beet hand in the center. The hand will melt, leaving a red streaky ooze and the fingers can be broken off and placed in individual servings.
