This Cup Tells You How Many Calories You're Drinking

If you're looking to lose weight, or just want to be more conscious what you're drinking, here's a new option: an intelligent cup called Vessyl. It claims to tell you exactly what's in your cup, measures the number of calories it contains, and helps you track your daily and weekly consumption with an accompanying app.

Vessyl is only the latest attempt we've seen at creating an accurate, portable food diagnosis technology, but it is perhaps the most elegant. Designed by Swiss wunderkind Yves Behar, it's sleek and smooth, and meant to be carried in the open.
