Step1
Before the performance, write the words "Denmark," "Elephant" and "Grape" on a piece of paper. Seal this paper in an envelope.
Step2
Set the sealed envelope on a table before starting the trick.
Step3
Ask for a volunteer from the audience and have him or her perform the following steps:
Step4
Think of a number between 1 and 9.
Step5
Subtract 5 from the number.
Step6
Multiply the difference by 3.
Step7
Square the product (multiply the product by itself).
Step8
Add the digits of the new number.
Step9
If the sum isn't a 1-digit number, add the digits of the new number together. Keep adding the digits of each new sum until you get a 1-digit number.
Step10
If the new 1-digit number is less than 5, add 5 to it. If it's greater than 5, subtract 4 from it.
Step11
Multiply the difference by 2.
Step12
Subtract 6 from the result.
Step13
Think of the letter of the alphabet that corresponds to this new number. (A=1, B=2, etc.)
Step14
Think of a country that begins with that letter.
Step15
Think of an animal that begins with the second letter of the country's name.
Step16
Think of the animal's color.
Step17
Think of a fruit that begins with the first letter of the animal's color.
Step18
Once the volunteer has gone through all of this, call attention to the sealed envelope that has been sitting on the table throughout the proceedings. Ask the volunteer what country, animal and fruit he or she thought of.
Step19
Have the volunteer open the envelope and display its contents. The volunteer, along with the rest of the audience, will be amazed at the fact that you knew the responses ahead of time.
