Engineering the Perfect Ice: Why Colder Isn't Always Better
The 2026 Milan-Cortina Winter Olympics opened on February 6, showcasing something never seen before in Olympic history. We're witnessing the first temporary indoor speed skating rink ever built for the Games. This isn't just a logistical achievement—it's a masterclass in materials science and precision engineering.
Mark Messer, a Canadian ice master with six previous Olympic venues under his belt, took on this unprecedented challenge. He's the ice technician at Calgary's Olympic Oval, which holds over 300 world records. Since late October, Messer has been constructing the rink at the Speed Skating Stadium in Rho, just north of Milan.
"Eighty percent of the work is done but the hardest part is the last 20 percent," Messer explained. Speed skating ice must be harder and colder than any other type. The blades are incredibly sharp—if there's any dirt, the blade loses its edge instantly.
The process is painstaking. The first layer takes about 45 minutes to freeze. Then Messer repeats the process hundreds of times. As the ice thickens, he uses hoses and even hockey sticks to spread the water evenly.
But here's where it gets fascinating: the water isn't completely purified. "Just the right amount of impurities holds the ice together," Messer noted. Different sports demand different ice compositions:
The goal? Skaters should glide as far as possible with each push, encountering minimal friction. It's crucial to eliminate dirt, dust, or frost—these create resistance that can cost precious hundredths of a second.
How Do Figure Skaters Defy Physics With Their Spins?
When you watch a figure skater pull their arms tight and suddenly spin like a blur, you're watching the conservation of angular momentum in action. Stuart Tessmer, an associate professor of physics at Michigan State University, points to friction as the central force in winter sports. But for figure skating spins, angular momentum is the star.
Here's the physics: angular momentum (L) equals moment of inertia (I) times angular velocity (ω). Mathematically, we express this as:
Where L is angular momentum, I is moment of inertia, and ω (omega) is angular velocity
When no external torque acts on the skater (we're ignoring minor friction from the ice), their total angular momentum stays constant. This is the principle of conservation of angular momentum.
What happens when a skater pulls their arms and legs closer to their body? The moment of inertia—basically how their mass is distributed—decreases dramatically. To keep angular momentum constant, angular velocity must increase proportionally.
"The smaller moment of inertia, the faster the spin," Tessmer explained. It's why a skater can go from a leisurely rotation to a dizzying blur in seconds.
Think about it this way: your body is like a rotating system. Spread your arms out, and your mass is distributed far from the rotation axis. Pull them in, and everything's closer to the center. Since L must remain constant and I just got smaller, ω has to get bigger.
What Physics Keeps Ski Jumpers Airborne for Seven Seconds?
Ski jumpers remain airborne for five to seven seconds, soaring distances that seem impossible. Three physics concepts govern their flight: gravity, lift, and drag.
Gravity is the constant—it pulls every object toward the ground with equal force. There's nothing athletes can do to change this. But they can manipulate their interaction with air to generate lift.
Lift is an upward force created when air pushes on an object. When lift roughly balances gravity, flight becomes possible. Ski jumpers achieve this by transforming their bodies into wings.
Athletes align their skis and body nearly parallel to the ground. They place their skis in a V-shape just outside the form of the body. This position increases surface area and creates the ideal angle of attack—the angle between the ski and oncoming air—that maximizes lift.
Research on full-scale ski jumping aerodynamics shows that lift increases as the angle of attack ((\alpha)) increases toward 30 degrees. Beyond 30 degrees, lift saturates while drag continues to increase.
The lift-to-drag ratio ((L/D)) is key. A high (L/D) means you're getting maximum lift for minimum drag—exactly what you want for distance. Increasing the angle of attack too much hurts this ratio.
Here's the catch: as drag reduces the skier's speed during flight, lift decreases too. Gravity continues pulling, so athletes begin falling faster until they land. The entire performance is a carefully calculated dance between these three forces. smithsonianmag
Tight-fitting suits are mandatory because loose fabric creates unintended lift. Ski length must correspond precisely to the jumper's height and weight. Too long or too short, and the aerodynamics don't work. smithsonianmag
Why Did the Olympics Ban 'Forever Chemicals' in Ski Wax?
The 2026 Milan-Cortina Olympics marks a turning point in sports environmental policy. These are the first Winter Games to completely ban fluorinated ski waxes containing PFAS—per- and polyfluoroalkyl substances. envirolink
For over 40 years, these super-slippery waxes gave skiers and snowboarders a dramatic speed advantage. One former racer described the edge as "ridiculous"—you simply couldn't compete without them. envirolink
The problem? PFAS is a class of 15,000 toxic chemicals that never break down in the environment or human body. That's why they're called "forever chemicals".
Studies found ski wax technicians had PFAS blood levels 25 times higher than the general population. These are among the highest occupational exposures ever recorded. The chemicals were also leaching from ski slopes into nearby water supplies. Park City, Utah detected PFAS contamination in three wells near a Nordic racing venue.
When skiers or snowboarders use fluoro wax, it gets into the snow. This contaminates the natural environment and drinking water downstream. The health implications are severe—PFAS exposure is linked to cancer, immune system problems, and developmental issues. youtube
Industry observers call this ban "one of the most significant materials-science shifts in Winter Olympic history". Elite athletes are still adapting to PFAS-free alternatives, which are measurably slower. But the trade-off is worth it: protecting human health and the environment.
We're watching a real-time experiment in sustainable sports science. Can athletes maintain world-class performance without toxic chemicals? The answer will shape winter sports for decades.
Can a Suit Really Make You 8 Percent Faster?
Dutch, Italian, and Canadian speed skating teams are debuting a revolutionary hybrid aerodynamic suit at the 2026 Games. Developed over four years with Eindhoven University of Technology and the University of Ottawa, this suit represents a breakthrough in speed skating technology.
Bert van der Tuuk, who's provided aerodynamic racewear to the Dutch Olympic team for two decades, calls it "one of the biggest revolutions in speed skating history". The suit is expected to provide an aerodynamic advantage of approximately 8 percent compared to conventional suits.
Here's how it works: the suit features a dual-layer construction on arms and legs. An inner tight-fitting base layer has closely spaced vertical ridges. A second outer layer stretches over it, creating a surface similar to drumskin.
This design promotes beneficial turbulence at speeds between 20 and 90 kilometers per hour. Sounds counterintuitive, right? But controlled turbulence actually reduces air resistance around the limbs, improving performance. The concept has been used in cycling but is new to speed skating at this level.
The suit also incorporates polyurethane-coated fabric to minimize air permeability in key areas like the back and upper legs. This further optimizes aerodynamics.
Dutch skaters Sebas Diniz and Stijn van de Bunt tested the suit during December qualification tournaments at Thialf arena. Diniz admitted initial hesitation about switching from his familiar suit but recognized the performance benefits. Van de Bunt cited wind tunnel test data from summer that clearly demonstrated the suit's speed advantage.
Both athletes noted the suit's fit is considerably tighter—particularly around arms and legs—but the improved aerodynamics provide a measurable edge. During the five-day qualification event, both successfully secured individual start positions for the Milan Olympic Games.
The three teams shared an investment of approximately 350,000 euros to develop this suit. That's serious money for a competitive advantage. But in speed skating, where races are decided by hundredths of a second, an 8 percent aerodynamic improvement can mean the difference between gold and going home empty-handed.
It's reminiscent of the Swift Skin suit introduced at the 2002 Winter Olympics in Salt Lake City, which similarly transformed the sport. That suit used careful fabric texturing to decrease aerodynamic drag and contributed to multiple Olympic medals and world records.
The Games Where Science Takes Center Stage
The 2026 Milan-Cortina Winter Olympics represents more than athletic competition. We're watching physics principles, materials science, and environmental responsibility converge on ice and snow. From Mark Messer's historic temporary rink to the PFAS ban that prioritizes human health over marginal performance gains, these Games showcase how science shapes modern sport.
The conservation of angular momentum explains figure skating's mesmerizing spins. Lift, drag, and gravity govern every ski jump. Ice chemistry determines whether a blade glides or sticks. Aerodynamic suits push the boundaries of what's physically possible at high speeds.
