It's turning into bubble wrap week around here.
Yesterday I stumbled onto a way to make amazingly realistic snakeskins. Take some small package bubble wrap, the kind with bubbles around 1/4 of an inch in size. Place it bubble side up on a sheet of glass. Hit with a heat gun on high. Tada! A cast off snakeskin.
Sadly, the occasions when you need some faux snakeskin are few and far between. I did think of two applications this would be useful for. The first is a gigantic snakeskin for a cryptozoology display. Roll out some bubble wrap, trim it roughly to the elongated V-shape of a real snakeskin, and hit it with the heat gun. During the meltdown process it seems to shrink about 60%, so you'll need a pretty long run of the stuff to make an impressive trophy specimen.
The second use would be as a surface treatment for the tail of a Fiji Mermaid style gaff. If you could shrink the bubble wrap around the tail structure you would get an excellent fish-like scale pattern.
