Gram staining is a fairly important microbiology technique, as many bacteria are classified based on the results of a Gram stain! I thought that the process was a pretty interesting way to distinguish between bacteria that have thick peptidoglycan walls (Gram positive) and ones that have a thinner peptidoglycan layer (Gram negative).
