This is all the more interesting because it's a snakebite puncture - i.e. two holes per tube.
The tube in question was from a 700 x 20, I haven't tossed the tube yet and will post a pic of it, once tied into a knot it is a bit tricky to get the tube back around the rim.
I was surprised how well it worked, could not feel the knot as it rolled. I am not sure how long it held air, the next morning it was flat.
