Thank you so much for the suggestion, I'll look into it. I haven't gotten a wallet for shows yet and it seems I should
I'll add some context to my question and also a idea that i thought would work (although it's still in development)context
: I'm giving a show about how people are not as random as they think and start with a NW number prediction. This prediction is read by one of the people in the audience and then a start explaining how numbers work in our minds (which is partially based on real science). After that i'd like to prove it by predicting multiple numbers in a row.
Because of the NW prediction already been read out by someone, I wanted to show this differently.My current idea
(before i read Satanica's post): Instead of printing the numbers on one sheet of paper, i'll have business cards with numbers printed on them, large enough for everone to see from a small distance. Using the OA principle I'll continue asking for numbers until they say the number i started with.
although this can be easily done with playing cards and some sleight of hand... i'm still figuring out a way to present it very open.
.....now i'm going to read about Jerry O'Connell Plus Wallet
