Why do wet fingers stick to ice?
Show answer & explanation
Answer: Water freezes bonding finger to ice
Cold attracts moisture — Wrong. Temperature doesn't attract. Water on finger freezes upon contact with ice surface, forming ice bond that sticks finger to block.
Water freezes bonding finger to ice ✓ — Correct! Water on finger is liquid (~body temp). Ice cube is well below 0°C. Contact transfers heat from water to ice rapidly—water freezes almost instantly. Frozen water creates ice bridge bonding finger skin to ice cube. Stronger than you'd expect! Pull hard = skin damage. Pour warm water to melt bond safely. Same principle: tongue on frozen metal pole in winter. Don't try it!
Static electricity holds them — Wrong. No static electricity. Sticking is freezing—water on finger solidifies upon ice contact, forming mechanical bond.
