This is absolutely hilarious. So you are claiming that your coffee will stay warmer longer in a 1mm thick plastic cup than a 6mm glass mug? TRY IT!! Gatorade bottle is about the same thickness of a tub make some coffee and pour it in a glass mug (about the same thickness as a 15gal tank) and in your gator aid bottle and see which cools quicker. Again it is not as easy as you suggest, equal thickness sure, but really, you have 6mm tubs???
