Step 1: Concentrate the sperm in your semen.
Step 2: Put it into a annular-shaped container (a ring formed by two concentric circles).
Step 3: Stand back to admire the beauty that is your very own semen vortex.
Apparently, concentrating the sperm induces them to align and swim in the same direction around the ring, creating a vortex... a vortex of semen!
Note: anyone attempting to make their own sperm vortex at home should definitely read the materials and methods of the full text for tips.
Symmetry-breaking phase transitions in highly concentrated semen. "New experimental evidence of self-motion of a confined active suspension is presented. Depositing fresh semen sample in an annular shaped microfluidic chip leads to a spontaneous vortex state of the fluid at sufficiently large ...
