The script
Say this slowly, one step at a time, and wait for a nod after each.
- “Think of a number from 1 to 10.”
- “Multiply it by 9.”
- “If you have a two-digit number, add the two digits together.”
- “Subtract 5.”
- “Turn that number into a letter: 1 is A, 2 is B, 3 is C, and so on.”
- “Think of a country that begins with that letter.”
- “Take the second letter of the country and think of an animal that begins with it.”
- “Think of the color of that animal.”
Then: “There are no gray elephants in Denmark.”
Why it works: any number from 1 to 10 times 9 gives 9, 18, 27 … 90, and the digits of each add up to 9. Minus 5 is always 4, which is always D. From there, Denmark is the country most people think of first, E suggests elephant, and elephants are gray.
When it misses
Steps 1 to 5 never fail. Steps 6 to 8 can. Some people pick the Dominican Republic or Djibouti; some choose an eagle or an emu.
- Reveal in stages. Say “you’re thinking of a country beginning with D” first. That is certain, and it sounds impressive on its own.
- If the country misses, say “and I suspect Denmark crossed your mind first.” It often did.
- Never claim certainty. Iris presents it as a test of how alike people think, not as mind reading. It plays better that way, and it is true.
Where it works best
On video calls and with groups, where everyone can play along at once. Then ask for a show of hands: who had an elephant?
Credit where due: A long-circulating schoolyard and party stunt. The arithmetic always reaches 4 for numbers from 1 to 10 (we checked all ten); the country, animal and color rely on the most common answers and can miss.
