In the clip below we can see that Red Bull have placed dry ice on the edge of the floor most likely to cool the electronics embedded in the Sidepod to the side of it. The fan blowing on the dry ice however gives us a little insight into the movement of airflow in that region, however we must remember that the airspeed and direction isn't indicative of track conditions. Still always nice to see airflow moving around key area's though!
