Red Bull-for-phones helps students focus

It's common to see students in class at universities focusing on their smartphones while their professors seem to be talking to the air. Smartphones and social media have changed people's lifestyles, and not all are good changes.

A drinks company has come up with a solution to make such students put away their beloved phones and concentrate on their lesson. Recently, in more than 10 colleges across China, students were able to "trade" the right to use their phones during class for a can of Red Bull.

Replacing a device students seem unable to step away from with a favorite beverage is a new and creative idea.
