THE RISKS OF LIFE Video Conference #3 Scams & Cons

2
Psychic Powers How does this card trick work?

3
The shuffle Cards are ordered 1234512345 Cutting the cards does not change the cyclic order. For example, a cut between 2 and 3 will move the card order to 3451234512, but the original 1234512345 is still there.

4
The 5 Card Piles the secret move Assume cards are in their original order…….. Counting 5 cards gives 12345 in one pile and 54321 in another. This is a PALINDROMIC STACK (values in one pile are exactly reversed in the other)

5
The Swaps The number of swaps is always one less than the number of cards in the pile. Consider only 3 card values. You could do 2 swaps in the first pile OR 2 swaps in the second pile OR 1 swap in the first pile and 1 swap in the second pile

18
Maths behind the Scam This will work any number of cards N that are placed in order in palindromic stacks. When we make N-1 swaps, as one card is moved down its equivalent rises in the other stack so that the ones meeting on top of the piles match.
