The ingenious design of the drinking bird (and what it is hiding under its hat)

Bill the Engineer Guy made this interesting video about the design of the drinking bird toy. I didn't know Albert Einstein spent 3.5 months studying it.

Bill reveals the operation and engineering design underlying the famous drinking bird toy. In this video he explores the role played by the water the bird "drinks," shows what is under the bird's hat and demonstrates that it can operate using heat from a light bulb or by "drinking" whiskey.
