  Exceptional points and skin effect, as the two distinct hallmark features
unique to the non-Hermitian physics, have each attracted enormous interests.
Recent theoretical works reveal that the topologically nontrivial exceptional
points can give rise to the non-Hermitian skin effect, which is
geometry-dependent. However, this kind of novel correspondence between the
exceptional points and skin effect remains to be confirmed by experiments.
Here, we corroborate the correspondence in a non-Hermitian phononic crystal.
The exceptional points connected by the bulk Fermi arcs, and the skin effects
with the geometry dependence, are evidenced in simulations and experiments. Our
work, building an experimental bridge between the exceptional points and skin
effect and uncovering the unconventional geometry-dependent skin effect,
expands a horizon in non-Hermitian physics.
