What does detonate mean?
"Detonate" is a verb meaning to explode, or to cause something to explode, with sudden force and a loud report. It applies both to devices that go off on their own — a mine detonates under pressure — and to deliberate action, as when engineers detonate controlled charges to demolish a structure. The word carries connotations of violence, precision, and drama, which is why journalists reach for it not only for bombs and fireworks but also metaphorically, as when a controversy "detonates" across social media. Derived forms include "detonation" (the act or result of exploding) and "detonator" (a small device used to trigger a larger explosion). The verb entered English in the seventeenth century from the Latin "detonare," formed from "de-" and "tonare," meaning to thunder — so at its root, to detonate is to make something thunder. Precise, vivid, and unmistakably forceful, it is the natural choice wherever an explosion is meant literally or figuratively.
(of an explosive device or substance) to explode suddenly and violently.
"The old shell detonated as workers were clearing the site."
Often used transitively for deliberate explosions: "engineers detonated the bridge."
to cause an explosive to detonate; to set off deliberately.
"Demolition crews detonated the charges at precisely six o'clock."
When you say "detonate," you are literally telling something to "thunder down" — the word comes straight from the Latin for a clap of thunder.

Etymology of detonate
The English verb "detonate" derives from the Latin "detonare," meaning to thunder down or to thunder out, built on "de-" (down, away) plus "tonare" (to thunder), the source also of English "thunder" through the shared Indo-European root and of "astonish" via Old French. It was adopted into English in the early modern period, around the early seventeenth century, alongside related forms such as "detonation." Its literal sense of explosive detonation became firmly established with the development of modern explosives and blasting techniques.
