Details:When a spatula is quickly inserted into a honey jar, its moving surface drags a thin layer of air into the honey. We discovered that such a simple process produces a remarkable structure in the air layer. This structure is ubiquitous, robust, and is suggestive of a new fluid-mechanical instability. I will show our measurements using new interferometric techniques and describe a new analytic understanding of the flows. | ||
