知名硬核科普频道 Technology Connections 用 30 多分钟彻底剖析了洗碗机的工作原理：为什么洗碗凝珠反而不如传统洗碗粉、预洗舱与主洗舱怎么配合，并用实验证明餐具进洗碗机前根本不需要水冲预洗。
为什么 HN 推它
HN 社区封神的洗碗机科普天花板；看似家常的话题被讲得逻辑严密、趣味横生，彻底颠覆了无数程序员的原有认知。
「强烈安利这个视频，看完彻底治好了我每次把碗放进洗碗机前都要先冲一遍的强迫症。」HN 网友原话：I highly recommend you watch this video by Technology connections[1], I too used to think I had to rinse my dishes before putting them in the machine.
英文原摘要（HackerTube / Claude 整理）
Technology Connections explains how dishwashers work, why detergent pods underperform powder, and how to use the pre-wash and main-wash compartments. It argues you don't need to pre-rinse dishes.
HN repeatedly recommends it as the definitive, mind-changing explanation of dishwasher use, even though it runs over 30 minutes.
