This is a picture of a old 8 barreled gun by Da Vinci. This was to
by lite and easy to carry around it was the need for you to have this gun
at the time. It was used for keeping people from trespassing on their
property. He was trying to simulate a machine gun. It had eight barrels for
more of a fire power and to stop your enemy. But it did not work as well
that Da vinci hoped because it did not fire really fast. (on the left side)

This a pictue of a machine that can lift pillars that were heavy to man.
Da vinci thought that this would be a good invention because it could take less time to move heavy objects without hurting the person.
This is another one of Da Vincis great and wounderful inventions. ( on the right side)
