Remember the Juicero? This $699 Wi-Fi-enabled cold-press juicer was the epitome of Silicon Valley genius, designed to press proprietary, QR-coded juice packets. Sadly, the only thing it pressed effectively was the patience of its investors, who eventually discovered the 'four tons of force' machine was entirely redundant, as the packets could be squeezed by hand. A tragic tale of innovation nobody needed, proving once again that some things are just better off with a good old-fashioned squeeze.
