Imaginary dice are great. The spectator will be firmly convinced that they are not marked. You can even demonstrate it by rolling a different number several times and naming it 🤣
You'd just automatically pick four for yourself, and your spectator would feel cool about it if you use the dice patter because he could roll an invisible die too and just name any whole number from one to six.
What if instead of a crimp, you spread through the cards and ask your spectator to pick one and use a pinky break over the bottom nine cards and have the spectator put the card on top and then cut the bottom cards and make it look like a random cut?😊
It’s an old one. The card starts out at the tenth position. You ask two people to name small numbers (less than 5). Say if was a 3 and 4. You add those up and subtract it from ten (3). Then you say you’ll count down to the totals of their numbers (7). You deal 3 cards and then as afterthought, put the deck onto the 3 cards, and ask someone else to do it. It will now be at 7.
Great! But It doesn't convince me that they can't say 4. If they say 4 you can count and do a DL. And that if they say 2 or 3 you can roll again is mmmmm, strange.
