Explainer Zone™ on Instagram: "DM For Credit / Removal 📨 This video captures a fascinating real-world physics and chemistry phenomenon where a soap bubble freezes almost instantly in extreme winter temperatures, typically below –10°C to –15°C. 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
