Foley

Tricks of the Foley artist. From The New Yorker:

Vegetables are old standbys: snapped celery for broken bones, hammered cabbage for a punch. (According to the Web site Atlas Obscura, during the climax of Titanic, in which Kate Winslet floats, shivering, on a piece of debris, Foley artists peeled back layers of frozen lettuce to add texture to the sound of her crisping hair.) Paper clips or nails, taped to the tips of a glove, are useful for the clicking footsteps of a house pet. Wet pieces of chamois leather, the sort that is used for cleaning cars, are highly versatile.
