The pipe grenade works great, but ... The grenade came by postmen in the shoebox. That would not be the worst, but the bottle was placed in a small plastic bag and only a piece of tissue paper (probably the former pairs of shoes) was wrong. The whole thing was was not padded and hurled around inside the carton. Two strips of adhesive tape holding the lid on the box. Whether the letter carrier knew what dangerous stuff they transported there.
