This creates a sudden discharge which you will feel as a shook and may even see as a spark, depending on the amount of discharge, ambient lighting, etc. If you don’t want to feel this discharge, try this: carry a metal object, such as a spoon, knife, nail file, etc. And prior to touching anything metallic, pull the metal device out and touch it to the item you are going to touch. This will allow the sudden discharge to occur through the device at the point of contact, away from your body. You shouldn’t feel a thing. Or at least not painfully.
