Woofle Dust (or foo foo powder, Magic Dust and other variant spellings, whufle, wufle, wuffle, whuffle, wuffle, whoofle) is a usually invisible, imaginary "magic powder" that the performer sprinkles over something make the magic work. It is used as a pretext to discard or steal something.
Early uses of the word in print are:
- 1926 the original mail order version of the Tarbell Course of magic. As part of the patter in lesson 2, within the "MYSTERY OF THE BURNING CIGARETTE" routine, Tarbell writes, "Sometimes I weight it down with a little Magic 'Woofle Dust.'"
- Sphinx, September, 1929 page 240, Everett Murphy mentions "woofle-dust".
- Sphinx, May 1932, page 99, Roennau mentions "foo foo powder or woofle dust"
