December 22nd - learning a new coin trick

Coin tricks are great. The reason why I like cointricks as opposed to card tricks. At least when It's done by a punter like me is:
1. To do a card trick you either have to wait for the occasion when you have a deck in front of you or you have to carry a deck with you. Carrying a deck with you makes you look like someone who carries a deck of card around. If you are a magician, that's alright, it's sorta expected of you. Not when you're just some guy of the street.
2. Card tricks are sometimes based on using a trick deck but this cant be done when using ordinary coins.

Well I know a couple of coin tricks already but I thought I'd expand my repertoire. So here's a trick to change this 10kr coin.

This trick will go down in history as one of the great. ones
