The museum likely decided not to include the plain plastic mixing bowl in the exhibit because it does not meet the criteria of being considered "art" in the context of functional American Kitchen art. The bowl may be too common or mundane compared to other objects that were chosen for the exhibit. Additionally, the museum may have focused on showcasing items that have more artistic or aesthetic value, rather than purely functional objects. Ultimately, the exclusion of the plastic mixing bowl may have been a deliberate curatorial choice to highlight more unique or visually interesting pieces in the exhibit.
