Drinking Bird Engine Experiment: what happens if you feed a drinking bird alcohol? This experiment compares the drinking rate (time per one full engine cycle) of two identical bird devices- but the glass on the left is filled with 70% isopropyl alcohol whereas the glass on the right contains tap water. After wetting the tops of both birds we count how many times each one “takes a drink” over a 5 minute duration (shown at x6 speed). This classic physics toy is a functional heat engine where cooli

The drinking bird toy works as water absorbed by its felt-covered head evaporates, cooling the head and creating a low-pressure area that pulls liquid up the neck. When horizontal, the liquid drains back, tipping it upright. The drinking bird toy is often used as a demonstration of basic thermodynamic principles, such as heat transfer and the conversion of energy. It's a simple yet fascinating way to illustrate these concepts in a visually engaging manner, making it popular for educational purpo
