THE HYDRAULIC DANCER.
Shape out a doll, A B, of light material, and paint or dress him prettily, as your fancy suggests, and between his legs set the cone, C, made of thin sheet-copper.
Fig. 107.
On placing this aquatic Blondin on a perpendicular jet of water, it will balance itself on the top, while rising and falling divertingly.
A hollow copper ball, an inch in diameter, will balance itself in the like manner, turning continually round its centre, and casting the water from its surface.
