Ooh, good, I can get crumpets, and maybe some ginger beer. :)

About the dandelion and burdock. What would happen if I put an emergency supply into my luggage, say a couple of cans into my suitcase that was checked-in and flew in the hold? Would they explode in transit or anything? I really wouldn't want to get dandelion and burdock over my clothes not to mention it might spark a security alert. Is it safe to put cans of fizzy pop in luggage? Or would it be allowed in the cabin?
