Vintage Retro Magic Sippy Dipping Bird - A Science Wonder

This vintage and novelty toy has been a childhood favorite for many years, evolved from a scientific invention used in thermodynamics and physics studies to demonstrate evaporation. Decades later, it became a perpetual motion novelty favorite among children of all ages.

The toy works by assembling the bird-like figure, inserting the metal bar on the neck into the holes of the legs. A small glass of water, smaller than the legs, is then placed in front of the bird, and the head is tilted into the water. The height of the bird is adjusted to make it bob back and forth continuously as it drinks the water, with best results achieved at a temperature of 25°C/76°F.

Measuring approximately 8 inches in height, this "magic sippy bird" creates a fascinating display of perpetual motion. As the water evaporates from the bird's head, the condensate rejoins the liquid pool in the bird's bulb, causing it to tip up again. This process continues indefinitely, making the Drinking Bird one of the oldest doodads that remains a fun novelty and gift.

The Drinking Bird is a versatile gift idea, suitable for decorating living or working spaces, filling up goodie bags, rewarding students, and more. It comes in a 2-pack, making it great for schools, retailers, party favors, and science fairs.

The curious office worker or science enthusiast who enjoys quirky desk accessories and appreciates the whimsy of perpetual motion will surely delight in the Drinking Bird. Classrooms, in particular, love this item, as it provides an engaging demonstration of scientific principles in a playful and captivating way.
