A cloud chamber gives us a glimpse into the invisible world of particles produced in the radioactive decay of naturally occurring elements and those generated when cosmic rays strike the top of the Earth’s atmosphere. It is a sealed environment containing a supersaturated vapour of pure alcohol sitting over dry ice. Charged particles passing through the chamber cause the vapour to condense leaving tiny cascading trails in their wake. These particles pass though us continuously without our awareness. Witnessing this usually unseen activity can lead us to look beyond what our immediate senses tell us is there and consider the possibility of other intangible phenomena.
