CES 2013: The fork that tells you off for eating too fast

Help

The makers of the Hapifork say it is the first ever "smart" utensil - a bluetooth-enabled fork that could help you lose weight.

Hapifork monitors your eating schedule, keeping track of how many times you lift it to your mouth. If you chomp down your meal too fast it will vibrate, forcing you to slow down.

The Hapifork was on display at CES 2013, the world's biggest consumer electronics trade show in Las Vegas.
