What Dyson Does With All Those Unsold Bladeless Fans

Maybe moving $US300 fans is harder than Dyson expected, or perhaps Dyson's engineers are just flat out of things to do. Either way, this Rube Goldberg-ian balloon course, made from God knows how many Air Multiplier bladeless fans, is mesmerising.

Dyson's official explanation:

Dyson engineers were asked to show how inducement and entrainment of air works on the Air Multiplier fan. If you watch closely, the balloon is sucked from behind and to the side of the fan this is inducement and entrainment at work.

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 isnt attached to anything).

And so we've found a lasting use for the Air Multiplier: as an interactive exhibit in a science museum. Throw in a smoke machine next time. [Techland]
