Magic Tricks

I am always looking for tricks that will fool my very intelligent 13 year old son. He always reverse engeniers everything and he is useually right and it is very disappointing for me. But This trick fooled him I also got another card trick, I think it was called "Or Not" that claimed to fool smart people and even magicians and that also rocked. Both tricks use a normal deck of cards and are very clean workers. I will be using both of these new tricks for a long time. Please keep them coming. I highly recommend this trick, so easy to do and so hard to figure out. Very clean, very powerful.
