Tea bag so explosively causes destruction (8)
I believe the answer is:
sabotage
'destruction' is the definition.
(sabotage is a kind of destruction)
'tea bag so explosively' is the wordplay.
'tea bag so' can be anagrammed to 'SABOTAGE'.
Though, I am not sure how the anagram is indicated.
'causes' is the link.
Can you help me to learn more?
(Other definitions for sabotage that I've seen before include "Vandalism" , "Wreck" , "Got a base (anag.)" , "Scupper" , "(E.g. factory) wrecking" .)
