Some dancing bobbins (5)

I believe the answer is:
reels
'some dancing bobbins' is the definition.
'reels' can be an answer for 'bobbins' ('reel' can be a synonym of 'bobbin'). I'm unsure of the 'some dancing' bit.
'dancing bobbins' is the wordplay.
'dancing' becomes 'reel' (reel is a kind of dancing).
'bobbins' becomes 's' (I am not sure about this - if you are sure you should believe this answer much more).
'reel'+'s'='REELS'
Can you help me to learn more?
(Other definitions for reels that I've seen before include "Scottish dances" , "Highland dances" , "Staggers about in Irish dances" , "Old film parts" , "Folk dances" .)
