What happens if you split an atom?

I was thinking of doing this later tonight after masturbating furiously to furry porn. My question is; are there any risks involved? I don't want to destroy the universe or something silly like that, I am a true American and I love my family, and my hero brothers that fight the evils of the world.

Splitting the atom is a misnomer.  You're spiltting the nucleus.

Seriously?

The free binding energy is partially expelled (radiation) and partially turned into mass to create two new stable nuclei.

If you really mean split an atom?  You get quarks.  Cool stuff.  Being done right now in some big high-energy physics labs.  It's recreating the conditions of the very early universe.  What happens?  If you can describe it well, you can get a Nobel Prize.
