In the Kids Cooperate social groups there has been a lot of interest in magic tricks lately. We have a cheap magic trick set that requires actual magic powers to pull off any believable tricks with, but that hasn't stifled interest or enthusiasm for learning and performing tricks.
For kids who are challenged by the pragmatics of peer social interaction because of Autism Spectrum Disorder, ADHD, or something else, magic tricks represent a social currency whose value rarely fluctuates. While typical social interactions can be unpredictable, the performance of a magic trick follows a clear and agreed upon social script that is followed explicitly.
I also have a theory that children on the Autism Spectrum enjoy magic for an opposite reason than of their neurotypical peers. While many people are thrilled by the mystery of the magic trick, kids who find every day social interaction mystifying are thrilled instead by the part of the magic trick social script in which the curtain is pulled back and the mechanics of the illusion is revealed. "A magician does not reveal their tricks" is not a response that is gracefully accepted to questions about how a trick was done in the Kids Cooperate social skills groups.
Here is a fun and simple card trick that is impressive and easy to master: http://youtu.be/tlQiuCeezUA
