What Happens If You Touch Dry Ice for 10 Seconds?

Dry ice sits at an astonishing -78.5°C (-109.3°F)—cold enough to freeze human skin on contact. But what actually happens if you hold onto it for a full 10 seconds? In this video, we break down the second-by-second cellular reaction when extreme cold meets living tissue. From the Leidenfrost effect failing to rapid epidermal freezing, frostbite, nerve numbing, and deep tissue damage—here is the science behind what sub-zero temperatures really do to your hands. What extreme temperature or science scenario should we test next? Drop your thoughts in the comments below! #Science #Physics #Biology #Chemistry #WhatHappensIf #Animation
