What site of internet haves really cool magic tricks ( videos or images ) and the tutorial of them?

Most sites that have magic tricks dont have the tutorials for them. It is unethical to reveal magic tricks in such a way. If you want to learn magic I suggest you buy a book or dvd of the type of magic you want to learn. Royal Road to Card Magic is a good book to start with for card tricks ($10US) and J.B. Bobo's Modern Coin Magic is good for coin tricks (also about $10US). You can try posting on a forum for more advice, I post at www.magihat.co.uk.
