If you need more routines, check out the Routines Manual.
Another simple routine to impress your audience (you can use this in sets too) is the “number reading routine”. Here’s how it’s done: tell the spectator to think of a two digit number between 1 and 50. Both digits should be different and odd…
Now eliminate the invisible options by asking whether it’s a ‘two-digit number’ (eliminates the numbers 1-9) and odd numbers (eliminates another twenty options). The most popular number people think off is 37. If you are writing the prediction down, make the ‘7’ look similar to the number ‘1’, as 31 is the second most popular number.
P.S. The popular answer for a number between 1 and 1.000 is 333.
P.P.S. Magic Bullets is a must-have.
