Nostromics

Are you or your friends fitness fans and science geeks? Then you'll love the Nostromics Lunar Weight Loss Gym Bag. The bag, which is great for your training at the gym, features a line drawing (credit: NASA) of an Apollo astronaut on the Moon planting a flag, with the Lunar Module in the background. Blue curved ON THE MOON text above the drawing and YOU LOSE WEIGHT, NOT FAT completes the design.

It reminds that, in physics, weight and mass are different. Weight is the force exerted on a body by gravity. Mass is instead how much matter or, um, fat, the body contains. You can cheat with your scale and lose weight by going to the Moon, but you won't lose any fat.
