Distilled water, glass flasks, glass tubes, resistance wire, stainless steel stands, halogen lights, control units, transformers
Each tube is mounted on round bottomed flasks filled one quarter full with distilled water and connected by a system of switches. An electrical heating element controls the air temperature inside the flasks. The flasks are lit from below, making the rising and falling of the water level visible.
