A groundbreaking study in *Nature* reveals that an object’s electric charge accumulation, such as when rubbing a balloon on hair, is influenced by its prior interactions. Researchers found that repeated contact with the soft polymer polydimethylsiloxane (PDMS) leads to consistent charge transfer outcomes, emphasizing how surface smoothness and contact history challenge traditional understandings of static electricity. This insight not only clarifies reproducibility issues but also enriches our grasp of everyday phenomena. Source and details of the news
