Mixing cobalt to get answer in experimental gear (3,4)
I believe the answer is:
lab coat
'experimental gear' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.
'mixing cobalt to get answer' is the wordplay.
'mixing' indicates an anagram.
'to get' is an insertion indicator.
'answer' becomes 'a' (abbreviation eg in Q and A).
'cobalt' anagrammed gives 'labcot'.
'labcot' enclosing 'a' is 'LAB COAT'.
'in' acts as a link.
Can you help me to learn more?
(Another definition for lab coat that I've seen is " Scientist's protective clothing (abbr)".)
