Unexploding Static Mesh

Hi! I’ve done a lot of blueprint coding, but I haven’t done anything with slicing or exploding static meshes. I have a solid rock that I want to make an animation for. I want to explode the rock outward into maybe 15 pieces, and then somehow make an animation for those pieces reconnecting to form the original rock. I only need the reconnecting part of the animation–I don’t actually need the explosion part of the animation.

I’m not sure where to start, but I am very comfortable with blueprints and navigating UE4.

Please shoot any ideas at me!
