Like I discussed in my last blog, I will be adding in either artillery ammo or tank ammo into my Genius Hour. I have decided to add artillery ammo because of it's advancement in technology throughout it's history. 

In this picture, is one of the first kinds of artillery, used in the Civil War. These cannons were highly inaccurate, so they needed a round that could explode but cover a wide range of ground. The evolution of the artillery shell began here during the Civil War. 

Also, the modern day bullet may not seem as impressive as something like artillery, but it has come a long way since it was first produced.
