Drinker Tinker "Test of Skill" 5 cent. This is a great party game. Lets you know when you have had too much to drink. Operates on a nickel. The object on the game is to mover the ring from one side to the other with out touching the metal rod. Not as easy as it looks. The back ground light's up when you insert a nickel and goes out when you tuch the rod. Operates on one 6 volt battery. Works great. 21' wide, 20" tall.
