A Spell To Expedite the Development of Photographic Plates

[found by Tiffany Ng in a crumbling volume of an out-of-print physics textbook that has since mysteriously disappeared, mostly likely into a parallel universe]

Glass plate of a midnight run,
In the fixer boil and bake;
Flashlight of newt, and notebook of frog,
Eyepiece of bat, and lens of dog,
Matt's seat belt, and Huy's snake eggs,
Kangaroo rats, and more sig figs;
For a charm of pow'rful trouble
Like a hell-broth boil and bubble.

Chorus:
Double, double, toil and trouble;
Stop bath burn, and developer bubble.

Ad lib, repeating chorus after each verse.
