On bicycle tours, I like having some bottles of wheat beer in my luggage, which I carry in an insulating bag for six bottles.
Until now, I separated the bottles from each other with crumpled newsprint.
From now on, I'll have that in cool :-)

To keep the bottles in place, it requires (at least) two of them.
The thing proved its stability in today's four-hour bike ride - that had portions of off-road included.

The parts are connected by a round wooden rod (2x270mm, d=14mm).
