👉 Silly fluid, also known as Silly Putty, is an unusual substance that can be stretched, molded, and even thrown around like a putty-like material. It's made from a combination of polymers, specifically ethylene glycol dimethacrylate (EGDMA), which gives it its unique properties. When you rub your hands together, the polymer chains get tangled, creating a viscous, elastic material that can be deformed and then return to its original shape. This behavior is due to the way the polymer chains can slide past each other, allowing Silly Putty to be molded and reshaped. It's often used for creative play, educational demonstrations of polymer science, and even as a temporary adhesive. The name "Silly Putty" comes from its ability to mimic the elasticity and squishiness of real putty, making it a fun and memorable example of polymer science in action.
