If you’re trying to lose a little weight, or just keep your roommates dirty paws off of your food, this can is the way to do it.  Granted, if you’re using it to discipline roommates, you might want to buy these in bulk, since a few of them might turn up missing.  Just record what you need it to say, be it a message for someone else or you, and then pop it into the fridge.  It’s light activated so anytime you or someone else opens the fridge, it will then say the recording.  It runs on 3 AA batteries and  you can record a message up to 10 seconds long.  It’ll cost you £5.98 or about $9 from Drink Stuff.
