How to Perform the Mental Elephant Trick. The Mental Elephant Trick is a very easy mathematical magic trick that is more appropriate for younger audiences. You put the spectator through a series of calculations until she ends up choosing two words based on the numbers--words that you KNEW she would choose. Here is how to do it.
Have your spectator choose a number between 0 and 9 and double it. If she chooses 4, it would then be 8.
Add 8 to the number after Step #1. If you end up with 8, it would be 8 x 2 = 16.
Divide the Step #2 number in half (16/2 = 8).
Subtract the original chosen number from the new number. If she chooses 4, you will subtract 4 from 8 and end up with 4.
Convert this number to a corresponding letter: A=1, B=2, C=3, D=4, E=5, F=6.
Have your spectator think of a country that begins with this letter.
Have the spectator think of an animal that begins with the SECOND letter of the chosen country.
Look at your spectator and say, "Oh, you know there are no elephants in Denmark!"
This works just about every time due to the quickness of the calculations and because everyone will always end up with 4, thereby choosing a country starting with D.
If someone says they didn't choose Denmark or elephant, simply tell them you knew and were just making sure they knew there were no elephants in Denmark.
Ever since attending a David Copperfield performance in 2003, I decided I wanted to have the same eye-opening effect on others, that Copperfield had on me. After a few years of learning and non-stop practicing, I began performing magic on the streets, in houses, and anywhere else I could. With a wide array of experience, I am here to teach you about magic tricks, but also how to properly perform them in public. After all, if your performance is not up to par, the trick will fail.
