“One balloon and a couple of evenings after work — Dyson engineers show how inducement and entrainment works on the Air Multiplier™ fan.”

This video is fun and whilst it shouts “Hello. I am a hip and minimal video-that-wants-to-be-a-viral” it’s lovely. Engineers are doing engineering things in an entertaining and non-techy way. “We could line up fans!” we think. “I was great at dominoes when I was younger.” Suddenly the world’s inner-child suddenly wants to be a fan engineer when it grows up.

“Inducement and entrainment of the air” says Dyson. “Wheeee” I say.
