The history of "light as a feather, stiff as a board"

Background for The Craft — light as a feather.

The oldest account

Samuel Pepys (1633–1703) recorded the game second-hand, from a Mr Brisband who had seen it performed in Bordeaux: four young girls lifted a boy from the ground using one finger each, raising him as high as they could reach. To rule out a trick they repeated it on the cook — "a very lusty fellow" — and it worked.

So the sleepover game in the film is roughly 330 years old, and was already being tested for fraud in the seventeenth century.

Why it works

Four people lifting an 80 kg body take 12–20 kg each, which is well within finger strength. The illusion of effortlessness comes from three things: synchronised timing (asynchronous lifting fails, which is why the chant matters), people underestimating what fingers can do, and memory exaggerating a brief lift into a long float.

Why that is the interesting part

The chant is not a spell, it is a metronome — its function is to synchronise four people so they lift together. A ritual whose supernatural claim is false and whose practical mechanism is real is a very good object for thinking about what The Craft (1996) is doing with Audio and Editing in that scene, and about ritual generally as a Mise en scène problem.

Use with care

A tertiary source. Good enough for the Pepys anecdote and the arithmetic; not a substitute for a folklore history if this note ever grows up.
