ROCKETS BALLS(SECRET WEAPON)

# Rocket Balls are the latest Pentagon secret weapon to be splashed over the Internet. The idea is that you take a hollow sphere with a hole in it, made of rubberized rocket fuel. When lit, the rocket balls get very hot inside, and eject a high temperature exhaust through the hole.
#  Then, they propel themselves every which way, bouncing off hardened walls and breaking through doors into whatever they can get into.

# The key element is that they are not intended as explosives; it's the "rocket exhaust" that matters. The burning gas that propels the rocket balls will quickly heat the interior of a building or a bunker to 1,000 degrees Fahrenheit, destroying the contents.
# The inventor, Kevin Mahaffy, worked as an engineer at Air Force Research Laboratory's Rocket Propulsion Division, and then spent three years as the Chief of the Motor Branch overseeing solid and hybrid rocket propulsion.
# The random nature of the motion makes rocket balls ideal for destroying the interior of a structure. This might be your preference when taking out a chemical or biological warfare facility. Rather than blowing it up, and spreading deadly agents over the countryside, the building interior could be destroyed.
