Story summary

Research from Saarland University identifies molecular dipole interactions as the cause of ice's slipperiness, challenging a 200-year-old theory by James Thomson.
Shoe contact with ice triggers dipole interactions, leading to a liquid-like film formation from the ice's crystalline structure.
This effect occurs even at very low temperatures, creating a viscous film.
The findings impact winter sports equipment and transportation safety.
The research has significant implications for physics and daily ice interactions.
