Why Surgical Lights Cast No Shadows 

Surgical lights are designed to cast no shadows because they use multiple beams of light that overlap from different angles, making sure there are no dark spots during surgeries. Another cool science mystery is metamaterials-these are special materials that can bend light in weird ways, even making things appear invisible! Then there's the futuristic "fishnet," a type of material that could lead to invisibility cloaks by guiding light around objects. And have you ever heard of color-changing ice cream? It reacts to temperature and chemicals in your mouth, so it changes color as you eat it! These mysteries show just how fascinating and surprising science can be!
