By high-speed imaging, we investigate the impact of a drop containing a particle on the solid surface. The solid particle is inserted at the bottom of the drop, which impacts on the surface at different impact velocities. After the particle hits on the surfaces, it rebounds vertically through the bulk drop, and eventually emerges from its apex. We systematically varied the particle diameter, density and impact velocity, to characterize the velocity threshold above which the particle separates from the drop. The jetting of the solid particle also leads to some impressive liquid splashes.
