You all know about the Boston incident, right? Hopefully? Well the people who did it used a pressure cooker and turned it into a bomb. When the bomb exploded, it shot out shrapnel which hit people and even killed people. This remind you of something? Furthermore, once the shrapnel had fallen to the ground, it did not explode.
Now now, I might be going deaf and blind, but I do recall the authorities saying it was a bomb. So maybe that'll give you all something to think about.
