I got it. I've been looking for a way to smuggle wine on the plane for three years now. I found the apparatus thanks to these vials VinQuiry gives out to wineries for free.
It's not much, but if you decant wine into four of these guys on to the plane (so far, went through twice and not stopped once), there is enough to have a modest glass of wine, a piece of cheese, an ambien and wake up to La Belle France.
