The video, got from YouTube, shows a test done by Dyson engineers using many Air Multiplier, the patented Dyson's Bladeless Fan.
It show how inducement and entrainment works on the Air Multiplierô fan. If you watch closely, the balloon is sucked into the airflow from behind and to the side of the fan; this is inducement and entrainment of the air. On YouTube you can find also another one where the inventor Sir James Dyson explains how it works and also the analysis of Telegraph's "Gadget inspectors Express" of the equipment. The system is unique, and on the web you can find many other video and informations.
As written on You Tube "Lots of experimentation with different sized balloons and other objects produced this video. And although edited to include our successful attempts, the video is made from completely genuine footage (and no, the balloon isn't attached to anything). Find out more on Dyson fans web page".
