Levi’s Eureka Lab has concocted a new laser-wielding robot to make creating ripped and washed jeans easier and more efficient. It saves time, effort, and the Earth. Previously, factory workers used sandpaper and harsh chemicals to make jeans look properly worn in. The jeans were probably washed for hours, so that the blue color would fade out — even though those dyes would inevitably end up polluting the groundwater.
