Watur Door

A door is "barrier that will close the entrance to a room." The Watur Door is a door that pushes the limits of that definition, not to mention the actual functionality of a door. It is a continuously flowing vertical waterfall that fits in a doorway and will automatically shut off when the "handle" is touched, permitting someone to pass through without getting wet. Clearly intended as a decorative piece, since the water stream is quite transparent, it might be best used to outfit a gazebo in the garden, or used as an entrance to a steam room or sauna, rather than as the entrance to your home. Price: $2,000.
