A really old classic mental magic trick, this is actually based on a simple mathematical quirk. It’s a great magic trick to try on a friend or indeed on a member of an audience.

The Effect:
The magician apparently predicts the thoughts of the spectator..

How is this mental magic trick done?

1. Ask the spectator to choose a number between 2 and 9.
2. Tell them to take the number that they’ve chosen and multiply it by 9.
3. This should give them a two digit number. Told them to add the two digits of the number together. For example, if their number is 14, take the one and four and add them to make five.
4. Tell them to subtract five from the resulting number.
5. Ask them to take the number they now have and make it correspond to a letter in a alphabet. ie. A =1, B=2, C=3, etc.
