Abstract
A water kettle randomly selects lottery numbers as it boils water. The water kettle enables one to randomly select six numbers for a lottery game, such as the “Pick 6 Lotto” game. As heat is applied to the water kettle to boil water for tea, for example, through steam power generated by the boiling water, a set of balls is agitated. Each of the balls in the set has a number painted or otherwise associated with it. As the steam agitates the balls, the balls randomly drop into a tube. At the same time, the noise of the agitating balls alerts a user that the water has boiled. The design and colors of the kettle echo the themes of the lottery. Moreover, the shape of the kettle matches that of a lottery ball.
