Abstract: A nested vessel assembly includes a first vessel and a second vessel. The first vessel has a first body that extends from a first lip to a first bottom to define a first containment volume within the first body. The second vessel has a second body that extends from a second lip to a second bottom to define a second containment volume within the second body. The second containment volume is substantially equal to the first containment volume. The nested vessel assembly has a nested configuration in which the second vessel is releasably secured to the first vessel with the first vessel disposed within the second containment volume such that the first bottom is adjacent the second bottom.
