This clever prank, when twinned with a glass or bottle (provide your own), creates the illusion of a spilt pool of water. Place on the treasured surface of an acquaintance to secure that life-long friendship (not guaranteed).  

These are manufactured by Ming Shing, one of the pioneers of the modern joke industry, who have been creating jokes since 1963.
 
Not suitable for children under 3 years. Choking hazard due to small parts.
