Welcome to TM. In echoing everyone above why not become a magician. It is not just for sad geeky people with no friends, it can make you the life and soul of the party, and you don't have to wear a silly hat or a cape either. Anyway it seems youv'e shown at least a little interest in magic to come this far and track down this web site.
Anyway to answer your question and a good starter trick for anyone to learn is the unique coin you can get one from here
www.magicshop.co.uk
And i advise that you don't look for a cheap alternative of this effect i've had mine for a good few years now and with care of and attention you will never need to buy another. (be sure not to spend it though one of my mates used his as bus fare once, Dearest bus ride he's ever taken.)
Also If your going to do some effects for your friends make sure that you practice them until they are perfect. And remeber if your going to pay for some magic items never give away the secret or it just spoils it.
