File Name : s1.avi Caption : movie s1. movie showing a stentor cell splitting at an entrance velocity of 2.08 m/s at the cross junction of a symmetric hydrodynamic splitter. the flapping of the tail end of each fragment post-splitting could be caused by formation of streamwise vortices downstream of the cross junction. File Name : s2.avi Caption : movie s2. movie showing one of the smallest live stentor fragments generated from the splitting process. this fragment was formed after splitting using a symmetric hydrodynamic splitter at an entrance velocity of 2.08 m/s. the fragment is relatively transparent optically, has beating cilia and is membrane bound.
