  Oblique impact of drops onto a solid or liquid surface is frequently observed
in nature. Most studies on drop impact and splashing, however, focus on
perpendicular impact. Here, we study oblique impact of 100-micrometer drops
onto a deep liquid pool, where we quantify the splashing threshold, maximum
cavity dimensions and cavity collapse by high-speed imaging above and below the
water surface. Gravity can be neglected in these experiments. Three different
impact regimes are identified: smooth deposition onto the pool, splashing in
the direction of impact only, and splashing in all directions. We provide
scaling arguments that delineate these regimes by accounting for the drop
impact angle and Weber number. The angle of the axis of the cavity created
below the water surface follows the impact angle of the drop irrespectively of
the Weber number, while the cavity depth and its displacement with respect to
the impact position do depend on the Weber number. Weber number dependency of
both the cavity depth and displacement is modeled using an energy argument.
