Don’t you just hate people who drop by your home and raid your fridge without having the courtesy to ask for permission? How about sharing a house with your mates to return home only to discover that your tub of Ben & Jerry’s ice-cream has been halved without your stomach being the main beneficiary. The Recording Can Fridge Guard could help guard your territory as it works like an aural scarecrow within the confines of a fridge. Being light-activated, it will play back a recorded message that aims to instill a sense of guilt whenever your hand reaches for the desserts and chocolates inside. Powered by a trio of AA batteries, this cute little device retails for £6 each.
