When a liquid viscous bridge between two parallel substrates is stretched by accelerating one substrate, its interface recedes in the radial direction. In some cases the interface becomes unstable. Such instability leads to the emergence of a network of fingers. In this study the mechanisms of the fingering are studied experimentally and analysed theoretically. The experimental setup allows a constant acceleration of the movable substrate with up to 180 m/s$^2$. The phenomena are observed using…
