Vessel to spin with the top off (3)
I believe the answer is:
urn
'vessel' is the definition.
(urn is a kind of vessel)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for urn that I've seen before include "Vase with handles" , "a large vase as for cremation ashes" , "Pot, vase" , "Large vase for funeral ashes" , "Receptacle for ashes of the dead" .)
