Nice invention name Shanaya! You're right, buying too much food and wasting it is a common habit, so something for the home we can all use to help limit this would be very helpful. Having an interface completely stuck on the fridge itself means you would be able to see the list of contents regularly and clearly. When planning meals, just a quick look at the fridge would help you decide which foods to use up first! You have drawn a really neat diagram of this too. This is great thinking Shanaya, keep those ideas coming in!
