Very sadly, my antique pair of Air Nike shoes fell across the path of our experimental disintegrator beam and began experiencing decohesion the other night.
But, always one to invert a frown, I took the opportunity to dissect them.
You can see a careful extraction of the air sac membrane which I will preserve in casualdehyde.
I hold out hope that it may be worth something when (if) I return back to my time.
