that's pretty common. you can carry this and no one would know it's in your possession. you can walk out of your cell with it and stab somebody with it, stab an officer with it. >> the ingenuity behind some weapons is almost beyond belief. >> this is a paint ball. it's very hard, probably about very similar to a small rock. and what inmates do with this is they chip the paint off the walls and they stick it in a container and they heat the water and they soften the paint too with it and makes it very pliable and they can use it and round it into a ball such as this. and what they would do with this then is drop this into a sock and they could make some sort of weapon out of it. it's an extremely difficult substance once it's molded together and dries and hardens. they're very difficult to break. if you will take this and if you were using this as a sock, you could -- and again -- with the significant amount of force i slammed it against the desk here, it didn't break, it didn't even chip it.
