An interesting little animation

I was interested in seeing how long it would take for a frosted chip to clear through sublimation so I did a little experiment and here are the results.

I left the camera off for half an hour to reach room temperature and then turned it on and set the temp to -15deg C. Naturally the chip frosted over pretty much immediately. I then left the camera at -15 and took a series of images until it was clear again. It took 40 min to sublimate clear which is handy to know. Anyway here is the animation.
