Mind bender
Here is an
interesting stunt to carry around in the wallet, copy out the figures on a
piece of card as show in the figure below
The
total is 4,100
When showing it to
a friend, begin by covering up all but the top line, and ask him to call out
the figure. Move the hand down to reveal the second line, telling him to add
them together; move down to the third line, adding this figure and so on down
to the bottom. It’s surprising how many people will make the total 5,000. Try
it yourself and see!
