Are you effing kidding me? A 'low oxygen environment'? Who knew that chalk could be used to acclimatize. This is the same kind of ignorance of Brownian motion, among other things, that gives us Al Gore. Now if I can figure out how to make chalk create a 'low gravity environment', then we've got a business opportunity.
One can only imagine how many Twinkies contributed to the cops' shortness of breath, fainting at the sight of WHITE POWDER.
