Hair straighteners have been a part of beauty routines since their invention in 1909. But they require dry hair, the hot irons can burn skin, and the devices weaken locks over the long run. Dyson has hit on a 21st century solution: the Airstrait. The straightener, used with wet hair, blows 11.9 liters of hot air a second through 1.5-mm slots at a 45-degree angle, speeding up the process while preventing the sort of damage created by scorching-hot irons. The machine is powered by the company’s Hyperdymium motor. “It’s more than 100,000 r.p.m.—five times faster than an F1 engine,” says Low Chen Nyeow, senior design engineer at Dyson.
