Trick Mug. The story is told of a greedy king who loved to drink his wine but refused to share it with his kingdom. A wizard created a special goblet to teach the king a lesson. When the king filled the mystical goblet up to the line, the goblet would retain the liquid. If the king was greedy and filled the goblet above the line all the contents would pour out the bottom leaving nothing to drink.
We have recreated this miracle for your amazement. If you are greedy and fill it above the line, all the contents will pour out the bottom, fill it to the line, it works fine! Fill it to the brim, the results are grim!!
Caution: Do not use any liquid that will stain!!
