Breaking into your apartment's easier than you think

As soon as I saw this direct marketing from security firm ADT, I was blown away by its simplicity and how great an idea it really is. Basically, a flattened box is rigged with elastic bands and can be slid under apartment doors and then springs into shape suggesting that someone has broken in and placed the box there. Although I'm unconvinced as to whether everyone's door has a big enough gap under it, it is definitely a great conception.
