The answer die inside a Magic 8-Ball is an icosahedron.

An icosahedron has 20 different sides, so this means there are 20 different answer possibilities when you ‘ask’ the ball your fortune. These responses vary between 5 strongly affirmative answers (“It is certain”, “It is decidedly so”, “Without a doubt”, “Yes – definitely”, “You may rely on it”), 5 tentatively affirmative (“As I see it, yes”, “Most likely”, “Outlook good”, “Signs point to yes”, “Yes”), 5 non-committal (“Reply hazy, try again”, “Ask again later”, “Better not tell you now”, “Cannot predict now”, “Concentrate and ask again”), and 5 negative reponses (“Don't count on it”, “My reply is no”, “My sources say no”, “Outlook not so good”, “Very doubtful”). According to probability theory, it takes an average of 72 questions for all 20 of the Magic 8-Ball’s answers to appear at least once.
