Rattling tube, get a long stick (8)
I believe the answer is:
baguette
'long stick' is the definition.
'baguette' can be an answer for 'stick' (I have seen 'French stick ' mean 'baguette' so perhaps 'stick' could also mean 'baguette'). I'm not sure about the 'long' bit.
'rattling tube get a' is the wordplay.
'rattling' is an anagram indicator.
'tube'+'get'+'a'='tubegeta'
'tubegeta' is an anagram of 'BAGUETTE'.
Can you help me to learn more?
(Other definitions for baguette that I've seen before include "Get beaut of a French loaf" , "Bread roll" , "Long French breadstick" , "Long narrow French loaf" , "A long thin French loaf" .)
