Moving beef! Thought it was alive?! Shocking

Imagine a steak twitching on the plate—terrifying, right? But it's not alive. This creepy phenomenon happens when freshly butchered meat, especially heart or muscle, still contains ATP—the energy source for muscle contractions. Even after death, if ATP remains, muscles can contract involuntarily. No brain, no nerves, just pure biochemistry. It’s scary science in action! Watch this short to learn why meat might move… even when it’s dead.
