What would cause a car battery to explode?

Answer:

Answer

If you incorrectly connect two car batteries together, i. e. by crossing the cables (negative to positive, positive to negative), one or both of the car batteries will soon explode. The resulting acid splash will cause severe burns to the nearby onlookers.
