Skip to 0 minutes and 8 secondsNicodorus van Ryzin is a great magician! He performs a show every night in his own theatre, showcasing all sorts of tricks, for which he has become famous over the years.

Skip to 0 minutes and 22 secondsHe loves having a diverse audience at his shows: young or old; working class or wealthy. Well, in reality, he loves to make money, and this diversity is a good way to do so. Not only is van Ryzin a great magician, he is also quite good at economics, and he created his own pricing strategy in order to optimize his profit.
