Advantages and Disadvantages
Gunpowder's relatively low specific impulse (amount of thrust per unit propellant) limits its capacity of thrust production on larger scales. Fireworks are the simplest of solid rockets and the weakest. Evolution from fireworks brought about more complex solid-fueled rockets, which use more exotic and powerful fuels. The low-explosive properties of gunpowder, relative to the high-explosive properties of more advanced solid fuels testify to the "survival of the fittest," as the use of firework-type engines (for purposes other than entertainment or education) has virtually ceased since the late nineteenth century. Yet with all these drawbacks fireworks will continue to maintain their use as a traditional pastime with an on-going history of nearly 5,000 years.

Famous quotes containing the word advantages:
“When the manipulations of childhood are a little larceny, they may grow and change with the child into qualities useful and admire in the grown-up world. When they are the futile struggle for love and concern and protection, they may become the warped and ruthless machinations of adults who seek in the advantages of power what they could never win as children.”
—Leontine Young (20th century)
