This is one of the simplest methods used by Mentalists in discovering a number
thought of by an audience member .
A feat of this kind is not important as a single trick, but will be very useful as one
of many unexpected and surprising bits of magic with which you can amuse the
audience and show them varying facts of your knowledge of magic. 

EFFECT:
Ask a spectator to think of a number.
Then tell him to double it, mutiply the sum by 5,
and tell you the product.
You then tell him at once what the number he thought of! 

NO PREPARATION IS NEEDED 



SECRET:
The number thought of will be the
last number arrived at, with its righthand figure,
which will always be a 5 or a 0, removed.





EXAMPLE:
If a person thought of the number 10, doubling it would make 20,
and multiplying it by 5 would make 100. Cut off the righthand figure, which in
this case is a 0, and the original number, 10, is left.
