One hundred subsequent images of the high temporal resolution neutron imaging experiment showing the fall of H2O droplet and its subsequent mixing in the container filled with D2O. As the droplet is not the first one dropped into the container, the original D2O level is already contaminated with the H2O from the preceding droplets. The field of view of each image is 14.4 × 14.4 mm × mm. The images are normalized by an “open-beam” image that included the empty Teflon container allowing better visualization of the interaction of the two liquids.
