Moving House: Empty Box Idea: Ice box

I'm always one for wanting to try something out before I tell you about it, which is why this post has been sat in my drafts for a while.  However I think I'm going to have to admit defeat - the kids have gone back to school (well will have by the end of the week), I won't have a day off with my husband now until October and the sun seems to be intermittant.... I don't think we'll be having a BBQ any time soon (maybe next year).
