How To Kill a Tardigarde

I don’t know why you’d want to (they’re kind of cute, if also terrifying), but I’ve been researching tardigrades for a new book. And they are HARD to kill.

Heat? They can survive temps up to 300 F.

Cold? They’re fine at -200 F.

Pressure? They’d be perky at the bottom of the Marianna’s Trench.

Vacuum? They have been blasted into space and survived. Some laid eggs in space. Eggs that hatched.

They are tiny (1.5 millimeters long at most), harmless, and indomitable.
