Adding a small amount of RAT test buffer solution (designed to lyse and inactivate the virus to release viral antigen) to swamp water under a microscope. The effects on a protozoa captured in the incoming stream (from right of screen moving left) is visible. The pellicle breaks down, spilling the contents. If this were a virus, the contents would be picked up by the RAT test as a positive result for the viral proteins. Video has been sped up.
