Vitaminwater is offering the ultimate challenge: 100,000 if you can an entire year without using your smartphone.

If you think you have what it takes to break the cell phone addiction for an entire year, Vitaminwater is giving away this prize to one winner for the so-called Scroll-Free For a Year challenge.

The participant will get a flip phone which they can use for calls only. While it'll be tough to track if someone remained faithful, Vitaminwater said that they will use a lie detector test at the end of the challenge.

If you're feeling like doing this, post a photo or video on your Twitter or Instagram before January 8, 2019 and include the hashtags #NoPhoneForAYear and #Contest.
