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.

What causes bruising? Impact injuries to soft tissues cause capillaries, small blood vessels under the skin, to break. Red blood cells then leak out of the capillaries and collect under the skin, accounting for the color of the bruise. The color changes in bruises over time signal that healing is in progress and the body is metabolizing the blood cells in the skin. You may bruise more easily as you get older and skin becomes thinner.
