Splitting a 3D ball into 2 little balls

Hey guys I'm working on a game and i got stuck and need some help What i want to do is split a ball into 2 balls by shooting it. My current project can apply forces and give direction to it and all i need to do is split it by shooting it with a laser gun. İs there a way to split it by code or should i have to create animations of splitting it and destroying the bigger ball? I've searched the web for similar things like agar io but tutors aren't that understandable There is a similar question but couldn't apply it :(
