Aerial Screw

The Aerial Screw design is a precursor

of the modern day helicopter.

The drawing of Da Vinci’s concept

illustrated the compression of air that

was intended to lift the device off the ground.

Edu-Science Da Vinci Series Kits

Mechanical Drum

Leonardo da Vinci’s mechanical drum was

designed as 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.

The scientific genius of Leonardo Da Vinci is brought to life through

articulated models offered by Edu-Science. The inventions that inspired

these snap-together replicas are taken from the pages of Da Vinci’s

priceless and awe-inspiring notebooks.
