The clever constructions of Leonardo da Vinci: with these simple sticks, one can create a dome and a bridge that stand without glue or string and without a nail or screw! Admittedly, it takes a steady hand and a bit of finesse to set it up.
Instructions for dome and bridge are included.
The beauty of it is that you can start with one or two sections, which can then be expanded step by step to create a larger bridge or dome.
Combine the Sticks with other building elements to create stairs, bridges, houses, and other structures!
100 colored sticks in a wooden box.
Materials: lime wood, non-toxic water-based paint, oil finish based on the box.
