Your Phone,
Your Water Lab

You're at a remote stream or village well. You dip the corner of your phone case in the water, and within 30 seconds, your phone displays a color-coded analysis: "Safe to drink — Contaminants: None."

Then you pull out a soap sheet from the side slot, wash your hands with clean water, and check your messages—all without reaching for a separate bottle or kit. You just tested water and cleaned your hands using only your phone case.
