Subject: t 1,089
The Effect: You jot down your "prediction". Using
some number calculations, the spectator arrives at the
number 1,089. Your prediction and their number matches!
What You Need: A piece of paper, a writing instrument
and a straight face. Just jot down the number "1,089"
on the paper, fold it up and drop it on the table in
plain view.
The Method: This is very easy to do.
Give the spectator a piece of paper and a pencil. Tell
them to write near the top of the paper a three-digit
number, where all the numbers are different. Example: 289
or 302, not 303 or 555, etc. They must all be
different. (It doesn't work if all the numbers are the same
or if the number is symmetrical like 202.)
Tell them to reverse the three-digit number and if it
is a larger number than the original one, to put it
above the original number. If it is a smaller value,
ask them to write it below the original number.
Tell them to subtract the smaller value from the
larger value.
This is important: Ask them if the
resulting number is a two- or three-digit number. If it's a
two-digit number, you know that it's 99. But, just tell
them to put a zero in front of the two-digit number.
If the result is a three-digit number, just
continue.
Tell them to reverse the digits of the
resulting number and add both three-digit numbers together.
The result will be 1,089. Neat, eh?
