Sense Sonnet - Pumper

Bombadier Beetle

A bombadier beetle I be,
Named for a handy bomb I make.
When a predator hits on me,
I do bomb for my safety sake.
Hydrogen and sulfur I store
In separate gland compartments.
When a predator seeks to score,
A combo mixture I commence.
I am no chemist, I confess,
But I can make the bomb real fast.
Hydrosulfuric acid - yes!
The predator soon is aghast.

Predator's mouth - I am the prey.
I do my thing and bombs away.
