00:00Why do we get electric shocks when we touch? Science explains.

00:05Static shocks are brief electric discharges caused by built-up charges equalizing.

00:10Common in dry, cold air near metal objects or pets. They're short and usually harmless.

00:19Atoms have protons, neutrons, and electrons. Objects stay neutral until that balance shifts.

00:25Contact and separation move electrons, insulators hold charge, and an open path lets it dump.

00:35Triboelectric effect. Touching and separating materials transfers electrons or ions between surfaces.

00:41A rubbed balloon clings, shoes on carpet, or plastic on fabric behave similarly.

00:46Dry air is less conductive, so charge leaks slowly and voltage rises before a spark.

00:55Humidity adds thin moisture films that let charge dissipate. Heating removes it.

01:03Rubber or plastic soles insulate and store charge, while leather and grounded floors reduce build-up.

01:09Synthetics hold charge. Cotton and wool usually help, especially with humidity.

01:17Slides, car seats, fleece blankets, and office chairs generate charge through fast rubbing.

01:22Pet's fur charges from brushing or rolling on carpets, causing tiny sparks on contact.

01:27Most household shocks are minor, but sensitive electronics can be damaged by tiny discharges.

01:37Fuel, solvent, powder, or dust industries use ground and bonded equipment to prevent ignition.

01:47Aim for 30-50% indoor humidity with humidifiers, plants, or ventilation.

01:52Choose natural fibers, use softeners or dryer sheets.

01:56Moisturize skin and ground before electronics.
