This 8 oz coffee cup called the 'Tank Up' Mug will get you in the tank's-half-full mentality. With a mug that looks to be constantly requesting replenishment, you'll be able to work for that extra mile once you fuel up on more caffeine.

At risk of describing the 'Tank Up' Mug as a simple drinking vessel with a quantitative gauge, it should be noted that heat-sensitive printing technology is used that flushes the meter red according to the temperature of your tea.
