This Bi-plane 3D Puzzle is recommended for children of 5 years and older.
All the pieces of the puzzles slot into each other so the puzzle can be rebuilt as many times as you wish without glue. However, if you would like to display it on a shelf or in a cabinet we would recommend a bit of wood glue to keep it secure over a long period of time. The puzzles are made from wood so they can be painted with normal acrylic paint or spray paint.
The puzzles do not come with instructions. The reason behind this is because it is a puzzle… and the fun part is trying to figure out how all the pieces fit together as you would with a normal picture puzzle; so hours of fun can be had with the entire family joining in. But please do not fear as help is only an email away. Contact Xplore Designs via an email and we will gladly send you instructions to help you and assist in any way we can.
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first aircraft to fly, the Wright Flyer, used a biplane design, as did most aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag than a similar unbraced or cantilever monoplane wing. Improved structural techniques and materials and the quest for greater speed made the biplane configuration obsolete for most purposes by the late 1930s.
The tandem wing design differs in that one of the two wings is placed forward and the other aft, such that no horizontal stabiliser is necessary.
The term is also occasionally used in biology, to describe the wings of some flying animals. (Wikipedia
