David Bushnell created the original naval mines back in January of 1778 to help protect good old Philadelphia from the British. They were originally kegs filled with gun powder and a slow burning fuse.
In the Early 20th century the slow burning fuses were removed and replaced with a device that would make the bombs explode on contact. They were used as a form of defense from attacking navies.
I can't believe these giant heaps of concrete ever even floated in the water. They are so big I would assume that they would just sink to the bottom and serve no real purpose. I literally had no idea that they were created so long ago too, I knew explosives were used but I didn't know they were so strategic with them. Whenever I think of this type of bomb I think of the ones that the U.S. used in WWII, they are a similar design but made of metal and half long poles coming out from the circular center.
ReplyDeleteI think the layout you guys picked for the blog is really good. The colors fit perfectly with your theme. The top banner is really cool, I didn't know you could edit it like that.
