A soap bubble is made mostly of water with a thin layer of soap molecules that reduce surface tension, allowing the bubble to stretch and hold air. In very cold air, heat rapidly transfers from the bubble to the environment, causing the water in the film

Sean Anetsberger | Artist | Art & Creativity Coach on Instagram: "Comment DRILLS and I’ll send you info for the Drawing Drills course. Most complex forms start as simple ones. Cubes give you structure. Structure gives you freedom. When you learn to modify basic forms, you can turn clean geometry into mossy, crumbling rocks. Drawing Drills trains you to build from simple shapes so imagination feels solid instead of random. Ten minutes a day. Stronger forms. More believable drawings."

Explaining Biology on Instagram: "Biology doesn’t have to be confusing or boring. Sometimes, all it takes is a simple visual to make complex concepts finally click. Biological valves are found throughout the human body—inside veins, the heart, and other systems—working silently to ensure blood and fluids flow in the right direction. These valves open when pressure moves forward and close instantly to prevent backflow, protecting the body from serious complications. This quick demonstration shows
