The Magic Aperture.
Put several lighted candles upon the table, in a straight row and near together. Lay upon the table, in front of them, a large piece of smooth, white paper. Have ready a piece of pasteboard, large enough to conceal the candles, with a small hole cut in it above the middle. Place this so as to stand upon its edge between the row of candles and the sheet of paper in front, and there will be as many images of flames thrown through the hole and upon the paper as there are burning candles.
