There are some food-related physical phenomena that came to mind (monentarily) - 1) Visible (in dark room with mouth and eyes open) tribolectric arcs produced by fracturing crystals in wintergreen LifeSavers (tm). 2) 'Frito (tm) effect - (but it also works with carrots - my contribution to science) - about 80% of observers eating corn chips while looking at a computer monitor will observe display anomalies on the screen - at a previous job, we almost thought there was a problem with the isolated power source for a satellite earth station because the computer monitor was 'freaking out' while an operator was eating corn chips.

I personally had been concerned about adequate removal of Avena Sativa (Oatmealus Genericus) particulates from such cannisters prior to use as cameras. But, then, you probably all noticed I am concerned about numerous trivial issues that delay my progress in the art. :O) Murray (O:
