Rebound off a surface (8)
I believe the answer is:
ricochet
'rebound off a surface' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for ricochet that I've seen before include "Film" , "The rebound of a bullet off a surface" , "Rebound from surface as missile might - hectic or what?" , "Glancing bullet" , "Glancing rebound" .)
