Your eyes aren’t fooling you, that’s not Photoshop and its not fake, that’s an actual cloud hovering inside an actual room!  Dutch artist Berndnaut Smilde uses simple fog machine to make the actual clouds combined a  carefully regulations of the humidity and the temperature to create the coolest man made cloud you’ll see today. Even so, this installation exists for very few minutes before disappearing again inside the room. If you’re not there at the moment, you will not be able to experience this scientific sculpture.
