Bubble Tracks Key Ring

s that a hadron or are you just happy to see me? Clever (or not) simulated bubble chamber tracks on a button/magnet/keychain, replete with retro particle nomenclature. Some of you have mentioned that the tracks/labels are not accurate (and in fact violate several laws of physics). Jeez - it's an artist's interpretation, ya nerdz! Tell ya what: if it makes you feel better, point this out to strangers on the subway. You're on your way to making a new friend!
