My baby sister is having a birthday party soon and I'd like to do a few cheap, fun magic tricks that I don't really need to have anything prepared(all I got is a deck of cards). Can anyone tell me a few tricks I could do at the birthday party + how to do them? Also, I need a really awesome, complicated trick to show my brother, because every card trick I try, he figures out without even thinking. Please if someone can help me out, I'd appreciate it.
