Giant Microbes - Booger Mucus.

Dried nasal mucus is what we call boogers. Mucus is vital to your immune system since it catches wayward microbes before they reach your lungs. Surveys show that most people admit to picking their nose! Picking is not the best habit though, so why not pick this adorable little guy instead!

Fun Fact: The word booger originates from a variant of British dialect for unwanted, negative things. The words boggard, bogy, and bugger are all used for insults. People to call boogers “boogies” and this nickname slowly evolved into what people commonly use today.
