Stop those greedy roommates or family members from stealing your last brew with the Kitsch’N'Fun Can Fridge Guard. Shaped like an ordinary soda can, record a message up to 10 seconds long such as “Don’t touch that!” When the refrigerator door is opened, the light activates the device. The gadget can also be used to remind others to do chores or comments for a spouse/partner like, “Hey, you just ate a Twinkie. Drop it.” The Guard needs 3 AAA batteries (not included) and will set you back £5.98 (~$9.00.)
