This fork checks how fast and how much you are eating. If it starts to think you are overdoing it, it’ll let you know by administering a vibrating jolt. It’s like having a really mean, four-tined friend with you at the dinner table. It’ll then shoot that information to your phone so you can never forget what a glutton you were. Cool!
In all seriousness, wrapping your brain around portion control can be tricky so if this fork wants to help with that, more power to it. HAPIfork will launch in 2014 at a suggested price of around $100. More here.
