Academy 18174 Davinci Rolling Ball Timer
In addition to many iconic works of art and inventions, the restless mind of Leonardo Da Vinci (1452-1519) was frequently occupied with adding to his voluminous notebooks, filled with designs for machines and structures. This model kit reproduces one of those designs -- a rolling ball timer! You can reproduce the function of measuring time by rolling the iron ball into the groove and moving the center of gravity. This kit assembles without the need for glue, and instructions in English are included.
This is an assembly kit of a space exploration vehicle or other non-fictional mechanism.
