How to use Rigidbody.AddExplosionForce ?

Hello guys,
I’m looking for an explosion effect when I press a button. I came across the “Rigidbody.AddExplosionForce”.
Does anyone knows how to implement it ??? And could you explain it with a simple script module?

you need to attach a rigidbody component to work with explosion forces and then these will help you : Unity - Scripting API: Rigidbody.AddExplosionForcehttp://unity3d.com/learn/tutorials/modules/beginner/live-training-archive/fun-with-explosions

can i have this explosion in one sphere? if yes how? it’s like shooting a sphere and if the sphere is getting shot,then it exploses,

@imenbm do you want just force or a particle explosion
