Scientists Just Figured Out How Washing Machines Work?!

The video explores the mystery of how washing machines clean clothes, a process not fully understood until 2018. It explains the role of surfactants, which help remove dirt from clothes, and the stagnant core problem, where soap struggles to penetrate intra-yarn pores. The solution involves the rinse cycle and diffusio phoresis, which helps remove dirt more efficiently. Experiments using sodium laural sulfate demonstrated this process. The findings could lead to more efficient washing machines, reducing water and energy use, and potentially faster rinsing speeds.
