[Raak] Protective covering - no [ISP] sporty/gamey - no [Inkspot] Kitchen based - no (although in fairness, you could use or store it there if you wanted - but it would be most unusual) [Raak] Mackintosh - no [Projoy] Wellingtons - no [ISP] Eraser - no.

Just to elaborate a bit on the response as to whether it was a recreational activity, I might have unwittingly misled you with my reply. The object is used as a recreational activity, in that you would utilise it in your spare time and for fun, but it would be unlikely to have a a long term usage, like a hobby, or a passtime, hence my answering with a no. Hope this helps...

[Raak] Round - yes, it is!

[Inkspot] Hollow - hmm, sometimes yes, sometimes no. I think, however, that in the traditional understanding of hollow, you would not say that it was, so once again I'd plump for overall no.

[Raak] Wouldn't that be a protective covering?

[Phil] Yes, but the trend of all the other answers was too strong to ignore.

Lib has a lot to answer for.

OK, not terribly round and somewhat hollow, but I'll just throw it in and see if it causes any ripples.

Woof! What a lot of lovely guesses! [Raak] Packets of three - no (but arf!) [Inkspot] Discy, as Stanley Unwin might have it, - no [ISP] Frisbee - no [Projoy] Moving parts or rubber duckiness - no* and no [ISP] Hula Hoop - no [Raak] Wheeled - no.

*BUT clarification (as always): Whilst I say there are no moving parts, one element of the object will move if the item is utilised...

Persisting with Raak's line of enquiry :-)

[CdM] Used with other things - not specifically: It can be utilised alone without any problem though you might get more out of it if you involve other items [Inkspot] Sphere - it is not a sphere, [Irouleguy] Associated with a country/culture - no [ISP] Used indoors - usually yes, but it could be used outside, and I am sure has been, [Phil] Weekend use - this little beauty can be used at any time and is, [Chalky] Did it exist prior to 1950? - not according to my sources...

Round, but neither a disk nor a sphere. Hmmmm.
