Three Year 8 students from Hampton Academy Zoe Gahn, Catherine Ross and Natasha Palmer, pulled off an amazing achievement in the national Teen Tech awards 2014, held at the Royal Society Hall in London.

They entered their idea to Teen-Tech last term and were chosen from thousands of entries from across the UK to present their prototype to several celebrity judges.

The girls invented a fridge magnet which scans the bar-code on grocer items before they are put in the fridge. They explained 'A notification is sent to via an app, as well an alarm sound on the magnet. This means that you'd end up using any food before it gets spoilt, so the chances of getting food poisoning are reduced and also the amount of food thrown in the bin would significantly decrease too.'

Product consultants at Sainsbury's, Tesco's and M&S were impressed and gave wonderful feedback that helped the girls shape their product. A representative commented 'we look forward to using such a product in store, as it all done manually at the moment.'

The judges, who included Stephen Fry, James May and the Duke of York, were equally impressed and when the awards were announced the Hampton Academy trio were runners up against a national field.
