When an airplane crosses a cloud, it is impacted by multiple drops. They may freeze and form a thick layer of ice on the plane, which causes a reduction of the lift, an increase in the drag, and perturbation of the instruments. In the lab, we study the impact of a single drop of water on a supercooled substrate, and how the freezing pertubates it. We explore different cases: at room temperature, the drop impacts and retracts. For sub-zero temepratures, patterns can be formed as the drop retracts as it freezes. For the coldest temperatures, the freezing can even induce splashing.
