I need a force of a number that isn't impractical or use any clunky props(like dice, and ideally not even a deck of cards). I'd like to have one for a larger number anywhere between 1 and 200 and then one for a bit smaller, like between 1 and 10. Does anybody know something that would work?
An impromptui number-force works like, and feels like, real magic.
I just wanted to say that depending on the effect in question and how you design it, you could force numbers using a deck and then have the spectator +and an entire audience) forget that cards were involved at all. For psychological trickery, get Tricks Of The Mind by Derren Brown.
Other than that, continue your pursuit of a fantastic number force (sans decks, sans dice, sans irritating people who say 'sans').
