21”L x 21”W x 9.5”H (diffusion cloud chamber) | wood, glass, aluminum, plexi, beta source port, beta particle source (156 keV Max 10 microcurie Carbon-14), rare earth magnet (1,000 gauss)

The thin spindle like tracks seen ionizing in the alcohol vapor within the chamber are cosmic ray particles and radionuclides that are ever-present remnants from the expansion of the universe.
