You’re Not Skating on Ice… You’re Skating on Water 😳

💬 Quote of the Day

“You're skating on a bead of water that freezes as you go past it.”
— Neil deGrasse Tyson

🤔 Reflection Question

Did you think it was just that slippery too? 
Hit reply — I’d love to hear your take.

🧠 Insight

'An average person on ice skates exerts immense pressure, potentially reaching millions of Pascals (around 30 times normal atmospheric pressure) due to the blade's thinness (around 1mm) and weight distribution, causing localized melting or 'spalling' (ice crushing) that creates the slippery film, although the actual pressure varies greatly with weight, blade profile, and activity.' So thinking this, an average person exerts millions of pascals of pressure on the ice while skating and the needed amount of pressure to lower the freezing point of ice is this: 'Applying pressure lowers the melting point of ice, but you need incredibly high pressures around 2000 atmospheres or 30 000 PSI to significantly drop the melting point to near -22 Celsius at room temperature, it takes about 6 GPa (over 870,000 PSI) to induce a quasi-liquid state in confined 2D ice, but general melting usually involves adding energy (heat) rather than just force.'
