Make the Nobel Prize-winning demonstration the centerpiece of your classroom, museum, lobby, or science center. As seen on the cover of the October issue of Physics Today!

Few demonstrations of the universe of particles we live in are as compelling as the diffusion cloud chamber. Invented by Charles Thomas Rees Wilson (and eventually earning him the 1927 Nobel Prize, along with Compton), the chamber's supersaturated 2-propanol envelope reveals the passage of ionizing particles and rays from cosmic and terrestrial sources. The mesmerizing display is both abstractly beautiful and educationally rich – observers are amazed to see evidence of radiation that must have passed right through them on its way to show up as a vapor trail.

The viewing envelope, at 800mm, is uniquely large among commercially available cloud chambers, and the circular enclosure rail permits large groups to gather and watch the display. The uniform illumination and high contrast cooling plate make trails immediately visible.
