I have an awesome card trick to tell you about
It works like this
You take any number of cards numbered Ace to King (5 to 13) and arrange them so that when you put one card down, put the next card on the bottom, put the next card down and then but the next card on the bottom (repeat until out of cards) they all end up in order (A,2,3,4,5,6,7,8,9,J,Q,K).
Me and my friend ended up starting at 5 cards and worked our way up to 10 before we got stuck.
Post your scores in the comments. I’d love to see them.
