This clip shows the effect overhead operating lights can have on
laminar airflow in an operating theatre. Airflow was visualised using
neutral density helium soap bubbles. These remain suspended still in
air unless ambient airflow moves them - allowing them to be used to see
air currents as they move.
I know it's probably obvious WHY this happens, but they should really describe the physics and possible mitigating technologies or techniques.
