Phys gun that takes apart breakable objects and lets you fling them

I’m requesting a phys gun that takes apart breakable objects and the parts spread out a bit but still be held by the gun. Then be able to fling the parts at the same time. Here’s a picture of how I would like it:

I would like to see this as well. It is a question for a better coder though… Anyone have an idea where to begin?
