Physics offers tricks to escape slippery ice bowl

A viral challenge involves trapping people in a carved-out ice bowl, testing their ability to climb out on a highly slippery surface. An article explains three physics-based methods using frictional forces to overcome the slope. The bowl's spherical shape makes escape increasingly difficult as one ascends.

The ice bowl challenge, of unknown origin, places participants inside a hollowed-out icy sphere where the walls curve upward, becoming steeper with height. This setup amplifies slipperiness beyond that of a typical icy sidewalk, especially when attempting to go uphill.

Drawing on principles of physics, particularly acceleration and forces, the challenge can be tackled with three clever tricks centered on frictional forces. These methods leverage an understanding of how to generate enough grip and momentum to scale the bowl's interior without sliding back down.

As described, the bowl mimics the inside of a sphere, where gravity pulls participants toward the bottom while friction resists upward movement. Success depends on applying force in ways that maximize traction on the ice. While the exact techniques remain detailed in the source material, they emphasize practical physics over brute strength.

This challenge highlights everyday physics in extreme conditions, turning a slippery predicament into a lesson on forces and motion.

Scientists at the University of Konstanz have identified a new type of sliding friction that occurs without physical contact, driven by magnetic interactions. This phenomenon breaks Amontons' law, a 300-year-old physics principle, by showing friction peaks at certain distances rather than increasing steadily with load. The findings appear in Nature Materials.

Despite centuries of play and recent Olympic successes, the physics behind curling remains incompletely understood. Dr. Thomas Herring, a physics professor, explains the complexities of ice friction and stone movement in the sport. Originating in Scotland in 1511, curling challenges scientists with its pebbled ice and sweeping techniques.

Tom Marzin, a physicist at Cornell University, has created a formula to predict how many times a crêpe or similar flexible material can be folded. The formula hinges on a single number called the elasto-gravity length, balancing gravity and elasticity. He will present the findings on 20 March at the American Physical Society meeting in Denver.

Top event riders Chris Bartle and Tom Crisp provide techniques for negotiating drop fences where horses cannot see the landing. They emphasize giving horses time rather than speed to build trust and use natural abilities. The advice appears in a Horse & Hound article published on February 19, 2026.
