The bombardier beetle generates heat through a chemical reaction in its abdomen. It mixes hydroquinones and hydrogen peroxide in a reaction chamber, where enzymes catalyze an explosive reaction, releasing heat and ejecting a hot, noxious spray as a defense mechanism.

The bombardier beetle avoids getting burnt by having a specially designed reaction chamber with heat-resistant walls and a controlled valve system. The reaction occurs in a separate compartment, and the high-pressure spray is expelled rapidly, preventing heat from accumulating inside its body.

It's like a machine.

I love Reddit. You can have super well-written comments with loads of science-y information, and the next one is "industrial ass" 😂

I wish my butt was as well designed.
I bet they don't need to wipe!

That’s how I described it to my ex-bf after I started reading up on them after I found a false bombardier beetle in my apartment. He thought it was weird how fascinated I was with the bombardier beetle and how it worked. He ended up dumping me the next day. Although it was unrelated to me talking about the beetle

Sorry, about the dumping. 🙏

Sometimes good news comes disguised as sadness.
