explosion

Whether it's a bursting balloon or a detonating bomb, you're sure to notice an explosion. An explosion involves a sudden and often violent burst of energy.

The noun explosion is useful when you're talking about a watermelon smashing on the pavement or the burst of fireworks overhead, but it can also describe a sudden increase in something, like an explosion of excitement at a birthday party when the pony arrives. Originally, explosion was used to mean "scornful rejection," from its root in the Latin explodere, "hiss off the stage," and a disappointed audience today might still be described as "exploding with boos."
