Smart glass

Smart glass is glass that can change its transparency to either become clear or opaque. It is like magic glass that can change colors! Normally, when you look through regular glass, you can see things on the other side. But smart glass can change its property to allow only some light through, like a filter.

Smart glass has a special layer of material inside it that can change its properties when it is triggered. It can be triggered in different ways, either by electricity, heat or even sunlight. When the smart glass is triggered, the tiny particles inside the glass move around, changing the way it looks.

For example, if you want privacy and don't want anyone to see inside your home or office, you can turn on the smart glass to become opaque or cloudy, so no one can see through it. When you want to see outside or let in more light, you can turn off the smart glass to make it clear and see-through.

Smart glass has lots of uses, like in windows in skyscrapers, car windows, and even in airplane windows. It is also used in privacy screens, computer screens, and televisions. Smart glass is a fantastic invention because it allows us to control how much light we want to let in and how much we want to keep out, helping us save energy costs and keep our spaces private.
