The scientific genius of Leonardo Da Vinci is brought to life through this articulated model. Taken from the pages of Da Vinci's priceless and awe-inspiring notebooks. Manuals are very educational and teach how these inventions have evolved into what they are today.

• Leonardo da Vinci himself said that because it was a lethal weapon, it must not fall into enemy hands
• This may be another reason why instead of drawing the final project, he drew it disassembled and in a way that makes it difficult to understand
• A boat with sails has a part that is submerged in the water and invisible to enemies
• The pilot used a passage to get into the lower part undercover:
• A pulley and rope system lowers the submarine, which can unhook itself underwater and proceed invisibly towards the enemy
• The submarine has two air chambers, which can be used for steering and for air needed by the pilot, who has a mouthpiece
• Steering underwater is done by means of a mechanical system
