Bubble Flow Glasfeder

When you grasp the lower end of the pen’s spherical ball, the liquid inside the ball magically rises, continuously producing bubbles, as if it has its own life. When you gently release your grip, the cool air allows the liquid to return to the lower part, back to its initial state. This is because your warm hand turns the liquid into gas, simultaneously increasing the pressure, and pushing the liquid to a new height. When you remove your hand, the temperature of your hand decreases, causing the liquid inside the container to cool again. This leads to the gas reverting to liquid, and the pressure decreases. The reduced pressure causes the liquid in the ball to flow back to the bottom of the container to restore balance. https://mr-sci.net/wp-content/uploads/2024/01/%E6%9C%AA%E5%91%BD%E5%90%8D%E8%A8%AD%E8%A8%88-23-768x768.png Temperature-controlled bubble glass dip pen allows you to experience a simple and fascinating physics experiment. It demonstrates the connection between liquid and gas and how they are influenced by temperature and pressure. Not only does the temperature-controlled bubble glass dip pen have a unique design, but its temperature control feature also provides an optimal writing temperature. The smooth flow of water makes writing effortless. In addition to its practicality, it presents a more engaging way to demonstrate physical phenomena and educate on scientific principles. The glass material provides a perfect connection with paper, ensuring smooth and comfortable writing, and offering you a high-quality writing experience. Whether you are a student, artist, or calligraphy enthusiast, you can find a pen that meets your needs. https://mr-sci.net/wp-content/uploads/2024/01/pen-768x940.jpg Due to manual craftsmanship, there may be slight color differences, which are normal phenomena and do not affect usage.
