Balloon sweeps illusionary path through Dyson Air Multiplier Fans

Engineers at Dyson were asked to demonstrate how something can be induced and made to sweep through the airflow path of the Dyson Multiplier fan.

The engineers carried out numerous experiments with different sized balloons and other objects to produce this mildly entertaining video.

The video however was constructed from a large number of trial and error attempts which in the final edit creates an illusion that the path the balloon takes through the fans is an induced continuous airflow.

Nevertheless, if you watch the almost soundless video closely, the balloon is sucked from behind and to the side of the fan and this is, as the engineers describe, an example of "inducement and entrainment at work."
