Particles on the Wall (POTW) is an interdisciplinary group exhibit exploring elements of science and the nuclear age, Hanford history, their thread through our lives and their bearing on the Columbia River and natural world. The goal of the exhibit is to unite the arts and sciences to forge a more healthy and peaceful world, while exploring Hanford history and the nuclear age.

Exhibit pieces illuminate key events regarding the nuclear history and role of nuclear technology in Washington State, current concerns with radioactive contamination, and the quest for peace. Given the magnitude of the topics, the tone of the exhibit is one of quiet commentary yet restraint, to best impart both the need for concern and an element of hope in the face of issues on war, peace, and the nuclear age that rest in our own back yards.
