Clos gets Stressed

Meet Clos – an ordinary bacterium with a superpower: staying calm under pressure. Clos is a real bacteria called Clostridium, which lives in the soil, quietly helping the garden grow, until one sunny day she finds herself in a serious situation… baked into a mud pie!

Clos Gets Stressed introduces young readers to the fascinating world of microbes through a lens of curiosity and perseverance. When things get tough, Clos forms a magical protective shell called a spore, allowing her to survive heat, drought, and even being launched through the air. It’s science, made playful, relatable, and unforgettable.
