The Shocking Science Behind “Bloody” Horror Scenes!

Ever wondered how horror movies make those realistic “knife cuts” without hurting the actors? 🎥🔪
It’s not CGI — it’s chemistry! Actors apply potassium thiocyanate on their skin, while the blunt knife is coated with ferric chloride. When the two meet… instant blood effect! 😱

100% safe, totally painless, and incredibly realistic.
Sometimes, the science behind the scare is even scarier than the horror itself.
