Elasticity: Why Rubber Bands Stretch and Snap Back

  1. Elastic Nature: Elasticity is the ability of a material to stretch and return to its original shape.
  2. Rubber Magic: Rubber bands are made of long polymer chains that act like tiny springs.
  3. Stretch Mode: When you pull, the tangled chains straighten out and extend.
  4. Snap Back: Release the pull, and the chains coil back to their tangled state.
  5. Energy Storage: Stretching stores potential energy, which is released when it snaps back.
  6. Heat Effect: Warm rubber stretches more easily because heat loosens molecular bonds.
  7. Cold Stiffness: At low temperatures, rubber becomes brittle and less elastic.
  8. Limit Point: Pull too far, and the bonds breakβ€”causing the rubber band to snap.
  9. Everyday Helper: Elasticity makes rubber bands perfect for bundling, holding, and gripping.
  10. Universal Science: Elasticity also explains springs, trampolines, and even how your skin flexes.
