The Mortise Crystal

Glass or plastic bottle

Mortise Crystal is a bottle that once empty, becomes a kind of building material, almost like a lego block. This idea comes from mortise and tenon structures. This feature enables bottles to be locked together like Lego. The structure can be locked in 3 directions: horizontally, longitudinally, and vertically. The bottle can be made of glass or plastic, in different colors and transparencies. They can be assembled into a wall like bricks, to create an actual building or for play such as a child's castle, or even a work of art.
