The scientific genius of Leonardo da Vinci is brought to life through this articulated model. The invention that inspired this snap-together replica is taken from the pages of Da Vinci's priceless and awe-inspiring notebooks. This model is made of plastic, snaps together and requires no special tools. The manual is very educational and teaches how this invention has evolved into what it is today. Leonardo da Vinci's Mechanical Drum is a cart equipped with an amply sized drum. When pulled by its handle, the gears turn the two lateral drums, which are fitted with pegs. The pegs move a total of ten drumsticks that cause them to beat the large drum. No batteries required. Also known as DV001.
