Developers have been searching for interesting ways to use 3D Touch since it was introduced on the iPhone 6S last year, and now Google has come up with one of the more clever uses of it: a button that just displays weird facts. With an update to the core Google iOS app yesterday, you'll now find an "I'm Feeling Curious" button as one of the shortcuts displayed when 3D Touching its icon. Press it, and the app will open up to a random question — like "How many hairs are on your head?" — its answer, and a button to generate another one. It's a fun addition that shows Google is still willing to dedicate space to lighthearted features — even if they're not all that useful.
