I know it sounds like a Merton question, but I have photographic evidence here.
Every now and again, when I look in the studio's freezer, one of the ice cube is not like the others.
I got 'em on camera this time. One lone cube just reaching for the sky.
I have theories as to why this may occur that involve convection currents, and turbulence from the freezer's fan, but the one that seems most plausible to me is: I don't think the bulb is going out when the freezer door shuts, and on the quantum level some ice cube are similar to moths, and are inexplicably drawn to the light.
