Features: ⭐ New condition in original illustrated box; open box, apparatus unused ⭐ Classic Drinking Bird evaporation heat engine with glass body and weighted base ⭐ Demonstrates thermodynamics principles through continuous bobbing “head dunk” motion ⭐ Approx. 7 inch tabletop science novelty with colorful retro-style design ⭐ Ideal for physics classrooms, STEM demonstrations, office desk display, or nostalgic science gifts ⭐ Maintained in a smoke and pet-free environment This classic Drinking Bird is a longtime scientific novelty that uses evaporation and heat transfer to create its continuous bobbing motion. After dipping the felt head in water, the liquid rises and the bird repeatedly tips forward — often mistaken for perpetual motion, but actually a clever heat engine demonstration. Compact at about 7 inches tall, it makes a fun desk gadget, educational physics tool, or retro-inspired gift. A great conversation piece for classrooms, offices, or collectors of vintage-style science toys.
