How it works
Evaporative cooling on the wet head creates a temperature difference between the head and bottom bulb. This causes the methylene chloride vapor inside to condense, making the bird tip forward. When the beak dips in water, the head gets wet again, and the cycle repeats.
Controls
• Start — begin the oscillation
• Wet Head — manually wet the head
• Heat Lamp — increase evaporation rate
• Temp — ambient temperature
