Studies of wrinkles are driven by areas relevant both in nature and in industry. However, recent research on wrinkles are mostly limited to slender elastic membrane. Herein we present a new observation of wrinkling generated by the impact of a viscous droplet into a liquid pool, in hope of enriching the knowledge of wrinkles genealogy.
