Here's some more new technology that science is bringing to shops for the future:
Apparently the technology inside the box only costs 10 cents. The supermarket shelves would need to have some kind of electric conducting strip on them though to make the boxes actually light up. So it would only work in the supermarket, not in your cupboard at home. Thinking about it, if this got popular and the supermarket had the flashing lights right down the aisle it could look like some kind of disco nightclub, so they may as well give the shop a dance floor too.
