How heat-shrink tubing reacts when exposed to the arc of an electric-arc lighter

The heat-shrink tubing shrunk, but not in an aesthetically pleasing way.

If you’ve ever wondered what the arc of a flame-less lighter would do to heat-shrink tubing, the above photo may be of interest. In addition to having a rough texture (a consequence of the unevenly pockmarked surface), it seems more rigid in a sort of this-stretch-of-tubing-will-be-brittle-sooner sort of way than the same type of tubing shrunk using a regular lighter’s flame.
