On overcharge, a battery becomes a âwater-splitting deviceâ (electrolysis) that turns water into oxygen and hydrogen. A parallel can be made with the fuel cell, but this device does the opposite; it turns oxygen and hydrogen back to electricity and produces water.

Black and blue marks are often associated with bruises. A bruise, or âcontusion,â appears on the skin due to trauma. Examples of trauma are a cut or a blow to the area. The injury causes tiny blood vessels called capillaries to burst. The blood gets trapped below the skinâs surface, which causes a bruise. Bruises can occur at any age. Some bruises appear with very little pain, and you might not notice them.
