|Magic 8 Ball|
|Inventor||Albert Carter/Abe Bookman|
|Company||Alabe Crafts Company|
An 8-ball was used as a fortune telling device in the 1940 Three Stooges short, You Nazty Spy, in which it was referred to as a "magic ball". While Magic 8 Ball didn't exist in its current form until 1950, the functional component was invented by Albert C. Carter, who was inspired by a spirit writing device that was used by his mother, Mary, a Cincinnati clairvoyant. When store owner Max Levinson was approached by Carter about stocking the device, he called in his brother-in-law Abe Bookman, a graduate of Ohio Mechanics Institute. In 1944, Carter filed for a patent for his device, assigning it to Bookman, Levinson, and another partner in what came to be Alabe Crafts, Inc. (Albert and Abe) in 1946. Under the Alabe name, they marketed and sold the device as The Syco-Seer. Carter died sometime before the patent was granted in 1948. Bookman soon made improvements to the Syco-Seer and in 1948, it was encased in an iridescent crystal ball. Though unsuccessful, the revamped product caught the attention of Chicago's Brunswick Billiards. In 1950 they commissioned Alabe Crafts to make a version in the form of a traditional black and white 8-ball.
The Magic 8 Ball is a hollow plastic sphere resembling an oversized, black and white 8-ball. Inside is a cylindrical reservoir containing a white, plastic, icosahedral die floating in alcohol with dissolved dark blue dye. Each of the 20 faces of the die has an affirmative, negative, or non-committal statement printed on it in raised letters. There is a transparent window on the bottom of the Magic 8 Ball through which these messages can be read.
To use the ball, it must be held with the window initially facing down. After "asking the ball" a yes-no question, the user then turns the ball so that the window faces him, setting in motion the liquid and die inside. When the die floats to the top and one of its faces is pressed against the window, the raised letters displace the blue liquid to reveal the message as white letters on a blue background. Although many users shake the ball before turning it upright, the instructions warn against doing so because it can lead to bubbles.
The 20 answers inside a Magic 8 Ball are:
- ● It is certain
- ● It is decidedly so
- ● Without a doubt
- ● Yes definitely
- ● You may rely on it
- ● As I see it, yes
- ● Most likely
- ● Outlook good
- ● Yes
- ● Signs point to yes
- ● Reply hazy try again
- ● Ask again later
- ● Better not tell you now
- ● Cannot predict now
- ● Concentrate and ask again
- ● Don't count on it
- ● My reply is no
- ● My sources say no
- ● Outlook not so good
- ● Very doubtful
Ten of the possible answers are Positive(●), five are Negative (●), and five are Neutral(●). Using the coupon collector's problem in probability theory, it can be shown that it takes, on average, 72 outcomes of the Magic 8 Ball for all 20 of its answers to appear at least once.
