culture swab

these things are so cool. you take a long q-tip and dip it into a wound (in this case, an abscess) and it gets covered in blood and pus. then you plunge it into this small plastic tube half-filled with gelatinous fluid, a culture medium. as the tip of the cotton swab pushes through the culture medium, blood and pus are lifted off the tip and suspended in the configuration of smoke slowly rising through the air.
