Office Ninja Stars
OK, I am all in to making weapons to shoot at my fellow co-workers but I think that this is pushing it a little.
This person put up instructions on how to make a Ninja throwing star out of Exacto blades.
This reminds me of the South Park episode when the kinds are pretending to me Anime cartoon characters and Cartman throws his Ninja star and sticks Butters in the eye. I could totally see someone doing that in a office and it being all over the internet.
I think their are somethings people should not be shown how to do.
