Story summary
- Researchers at Saarland University dispute the belief that ice slipperiness results from pressure or friction melting ice.
- They discovered that molecular dipole interactions between ice and shoe materials create a slippery film.
- This challenges nearly 200 years of theory proposed by James Thomson.
- Ice remains slippery at low temperatures due to a viscous liquid film formation.
- Material surface properties affect ice friction, influencing safety in winter sports and transportation.
