Case of electric crackling noise that's very high (8)
I believe the answer is:
ecstatic
'very high' is the definition.
'ecstatic' can be an answer for 'high' (thesaurus). I'm unsure of the 'very' bit.
'case of electric crackling noise' is the wordplay.
'case of' says to hollow out the word (remove centre letters) (outsides of).
'crackling noise' becomes 'static' (static is a kind of noise. I am not sure about the 'crackling' bit.).
'electric' with its centre removed is 'ec'.
'ec'+'static'='ECSTATIC'
'that's' is the link.
Can you help me to learn more?
(Other definitions for ecstatic that I've seen before include "Feeling great rapture or delight" , "Feeling immense joy" , "Rapturous" , "on top of the world" , "Showing great delight" .)
