The secret to bulletproof glass is… plastic! It’s called a laminate, and that’s a sandwich of glass, plastic, and glass, which is thicker than ordinary glass. The plastic inside the laminate is usually a polycarobnate material that’s really tough but still see-through. When a bullet is fired at a window of bulletproof glass, the bullet pierces the first layer of glass, but the plastic layer absorbs the bullet’s energy and stops it so the bullet doesn’t get through the final layer of glass. It’s not foolproof, but it’s a lot safer than regular glass!
