Destroy shattered objects after being smashed.

Good morning! I am new to coding and I have come to a problem with destroying the objects after the effect.

After using this video to create the effect, I am having problems to destroy the shattered objects afterwards the effect is done. I have done “Destroy(gameobject);” and “Destroy(Find(“name”clone”));”. But it still don’t delete the objects.
