💁🏻‍♀️ TIL: 🧲💡 Sang-Woo Kim’s team at #Yonsei University in #SouthKorea built a small floating capsule that purifies #water using only magnetism.

Shaking it for three seconds powers a sensor and generates electrostatic fields that pop open bacterial membranes, with no #batteries or #chemicals required.
