What you see here is a Self-Running Liquid Flask Wheel — a fascinating mechanism that rotates using shifting liquid weight and gravity. In this video, I explain how each liquid flask changes the center of mass, creating torque and motion. This model is widely used in science fairs, engineering education, kinetic art, and hobby projects. Even though it appears to run forever, it’s not perpetual motion — friction and air resistance eventually slow it down. Watch the full explanation and enjoy this beautiful engineering concept!

00:00This fascinating device is called a self-running flask wheel.
00:04It works on the idea of shifting liquid weight to create continuous rotation.
00:09Each flask is partially filled with colored liquid.
00:13When the wheel rotates, the liquid inside keeps moving to the lower part of each flask.
00:18This creates an imbalance, more weight on one side and less on the other, which keeps the wheel turning.
00:24But this rotation is not truly perpetual.
00:27It slows down over time because of friction and loss of energy.
00:32However, it beautifully demonstrates concepts like center of mass shifting, moment of force, torque, balance and imbalance in rotating systems, fluid dynamics inside moving containers.
00:46This makes it a great working model to visually understand physics in action, applications, educational demonstrations to teach torque, balance and fluid behavior.
00:56Science exhibitions attracts viewers due to slow, smooth motion.
01:01Engineering concepts explains weight distribution in rotating systems.
01:07Art plus physics models often used as decorative kinetic sculptures.
