Self‐Sustained Snapping Drives Autonomous Dancing and Motion in Free‐Standing Wavy Rings (Adv. Mater. 7/2023)

Self-Dancing Rings By exploring self-sustained snapping instabilities, in article number 2207372, Yao Zhao, Jie Yin, and co-workers report a self-dancing and crawling wavy ring under heat and light.
