Decomposing floater in place where kids play (8,4)

Ross

I believe the answer is:

paddling pool

I'm a little stuck... Click here to teach me more about this clue!

'where kids play' is the definition.
I don't know anything about this answer so I can't tell whether this works.

'decomposing floater in' is the wordplay.
I cannot really see how this works, but
'in' is present in the answer.
This may be the basis of the clue (or it may be nonsense).

'place' is the link.

Can you help me to learn more?

(Other definitions for paddling pool that I've seen before include "Children's bathing place" , "Small child's swimming bath?" , "Shallow water in which children play" .)
