Distilled water, glass flasks, glass tubes, resistance wire, stainless steel stands, halogen lights, control units, transformers
The glass tubes supported by metal structures are arranged in a line across the width of the room. 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.
