Stickiness describes the quality of adhering to a surface upon contact. It's what makes tape cling to a package or a lollipop adhere to your fingers. 🍭 The degree of stickiness varies depending on the substance and the surface. Think of glue versus a slightly damp surface; the glue has high stickiness. It's a property arising from adhesive forces between two materials. Basically, it's how much something likes to cling!
