It's Magic!

I was in a magic club in junior high school.  I know- nerd alert!

I only remember enough to do a few basic card tricks- enough to impress my kids (for the time being) and cause my wife to say "I didn't know you could do that!"- but the one element necessary for my basic tricks is distraction.  I'll talk while I shuffle, get the kids talking while I shuffle, anything to distract them from what it is that I am actually doing.  The more distracted they are, the easier it is to pull off the trick.

Take away the distraction, and you take away the magic.
