The Brachinus crepitans, or bombardier beetle, measures just 2 cm but wields a powerful chemical defense. When threatened, it mixes hydroquinone and hydrogen peroxide inside its abdomen, triggering an exothermic reaction that reaches 100 °C. It ejects bursts of corrosive benzoquinones at 500 pulses per second, burning and repelling predators. This precise, repeatable mechanism has inspired research into reigniting gas turbines in aircraft under extreme conditions as low as –50 °C. Its internal valve and chamber system is now studied in chemical engineering and advanced biomimicry.

And uses that peroxide to crap explosions at things. Extremely hardcore.

Big deal, I have explosive craps all the time.

Have you ever spray-farted someone's face off?

I'm under court order not to answer that question.
