Apart from manufacturing really cool-looking vacuum cleaners, Dyson is also the company behind those awesome bladeless fans. The only problem with these is their price: At $300 a pop, they’ve probably got quite a stock in inventory. I mean, I don’t know too many people who would pay that price for a fan when you can get a good one for about a tenth of the price. But the question is, what would YOU do with all those unused fans? Here’s what Dyson’s engineers came up with:

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).
