whaaat?
something i know that i know what it is. 
Simple! It's a classic experiment. You put a cat in a box, close it, poke a hole in it, put a gun in the hole and pull the trigger. YOU AREN'T ALLOWED TO OPEN THE BOX. The cat inside might be dead or alive, it's a demonstration of probability which is pretty much what quantum is about. The kicker is you'll never know because the box remains closed. The cat is dead, maybe.
The set would include a box, a plush cat with purring and horrendous screeching electronic sounds, and a fake gun. Premium kits would come with a real cat, but the gun would still be fake to avoid getting PETA on your ass.
