About this lesson
What makes slime so satisfyingly squishy? In this engaging 3-minute exploration, we dive into the molecular world of polymers and non-Newtonian fluids—materials that behave in counterintuitive ways. From the chemistry of cross-linking polymers to the physics of shear-thickening and shear-thinning fluids, discover how scientists engineer materials with properties that captivate our senses. We'll examine how borax, cornstarch, and other household chemicals transform into stretchy, bouncy substances, and explain the real-world applications of these materials in industries ranging from aerospace to cosmetics. Perfect for curious minds of all ages, this video demystifies the science behind some of today's most popular fidget toys and craft materials, revealing that play and physics are deeply interconnected.
