Balloon Wheels.
12. Balloon Wheels.
These are horizontal wheels, generally made of solid one-inch elm board, about two feet six inches diameter. On the top arrange and fix in pots, three inches diameter, and about six inches high, in number equal to the cases on the wheel: near the bottom of each pot make a small vent, into each of which carry a leader from the tail of each case; the pots may be loaded with Stars, Crackers, Serpents, &c. As the wheels turn, the pots will be successively fired, and caused to throw into the air a great variety of fires, which taking numerous and various directions, will present a pleasing exhibition.
