Drinking bird

• Here is an object that will bring back many memories. Without stopping and without an ounce of interruption, the drinking bird bends, drinks and straightens, then bends, drinks and straightens up almost endlessly without any batteries or motors!
• Her secret? Thermodynamics and the laws of physics! The curious blue liquid located in its belly is sucked in by the difference in temperature caused by the cooling of the bird's head. The bird leaned over and then the blue liquid returned to its belly. The effect is certainly much more fun than the explanation of why and how. A fascinating curiosity where conversations and explanations are going well around the drinking bird!
