CHINESE SHADOWS.
Opaque bodies, cut in various shapes, are held against a transparent screen, with a powerful light behind them. The audience are in a dark room.
Fig. 131.
To increase the effect, make the figures of acrobats, rope-dancers, performers on the horizontal bar, &c., of sheet metal, and fit them with joints, so that the limbs can be moved by mounting them on thin rods at right angles with the rope on which they seem to walk. These rods can be turned by cranks, or end in a cogged wheel locking in a ratchet.
