The makers of Vessyl, the $200 smart cup that helps dummies remember what they're drinking, released a Teens React marketing video featuring tech's finest thought leaders. And they're damn impressed: "The experience is one of those technology leaps that's indistinguishable from magic."

Cups: we all use them. But how do we know what's splashing around inside? Thanks to Vessyl, humanity will never again struggle to remember what we just poured into our glass.
