South African beer brand Castle Light jumps on the bandwagon of mind-controlled tech with a draft beer that is poured at the speed of thought. The "Extra Cold Mind Reader," developed by agency Hellocomputer, asked people to put on an EEG headset, then got them to think about "extra cold." The headset doesn't exactly read their mind per se, but measures conscious thought. The stronger the person's focus, the more beer goes into their glass.
The environment around the users challenged them as well, with interactive lighting, cold and hot air effects distracting them from their focus.
