Back in March, we asked you to send us your best idea for a gadget, app, service or some other slice of tech genius for the chance to win a week's worth of mentoring by Google's experts in our Stuff Launchpad competition.
Hundreds of you submitted ideas that were everything from completely brilliant to completely insane (many thanks to the guy with the electronic spoon, you nearly made it), and after hours of deliberation we picked six favourites to pitch their ideas to our judges - Russell Hall, co-founder of taxi app Hailo, Oleg Fomenko, co-founder of Bloom.fm, Niko Schröer, Google Office Hours mentor and Simon Osborne-Walker, editor of Stuff magazine - at Campus London.
Our fifth finalist has an idea that could save you money and combat one of the most frustrating problems in modern society: food waste. Supermarkets throw away vast amounts of food - Tesco alone wasted 30,000 tonnes of edible food in six months last year - and one-third of the food that does make it into your basket ends up in the bin. Justin's app helps people curb this crazy, insupportable trend by putting them in touch with food that's just been reduced.
