When two materials come into contact, electrons can transfer between them. This creates tiny patches of positive and negative charge. Those opposite charges attract each other, adding a small “electrostatic grip” on top of normal friction. That’s why things like paper, plastic, or your phone case sometimes cling to a table, a screen,
