Minneapolis airport had a Dyson Airblade installed in the men’s bathroom, perhaps in order to give Republicans one less thing to wait for while tapping their feet. What can I say? It works. I put my wet hands in, and the device started blowing quietly. I pulled my hands out slowly over the course of about 10 seconds, and when they emerged they were dry. The device shut off automatically. The air it blew was cold, not hot.
