Snapping of a trap under water. Time scale is indicated. An ink filament reaching into the trap with the ink drop is visible. During snapping, no noticeable distortion of the filament, but an outflow of bulk ink out of small gaps at the lateral trap parts is visible. The trap lobes move asynchronously, whereby the triggered lobe (the left lobe in the images) moves first. Images are from Supporting Information File 8.
