Riddle Multifunction Pot

Comes the weekend and how every Friday, we propose our usual Riddle, today we are facing a new case of things aren’t what they seem, because how you can imagine, this is not a potted plant, but something more and that something more is that today we have to guess.
How tracks one is in the image, the metal piece noted at medium altitude in which apparently is a conventional pot and older I tell that it is best used in external and that its role is not only decorative, but is a practical utility concrete for holidays and weekends of semana…
I think I am giving too many tracks and me you will guess too fast, but offset by other times that you have been more difficult, so all of you to give ideas and in a few hours as always, you’ll have the solution.
Update:
The truth is that I’m not surprised that most have not so successful because the cold that, at least where I live how that can not be used.

But it was a barbecue to prepare meat to grilled weekend in the garden, and invite friends, although for many invitations that it does because it is not very large but discreet and mona which is not.
