Now that's just silly. Of course it's possible. I've been doing it to my classmates since first grade and all the way until third grade when they told me it wasn't okay, and probably a crime. First, you get them to take their hand out and put the palm up, then you hit them fast and soft-- if you do it right, it doesn't welt.

You don't have to regret anything right now. You will once I catch you.
