After cutting the grass in the yard, the gas-powered lawn mower was stored next to a water heater. The heater was manufactured by Whirlpool. During the trial, experts retained by the plaintiff demonstrated that vapors from the mower's gas tank collected near the water heater and caused the explosion. Five-year-old David Walker was injured. There was nothing to suggest that David did anything to cause the explosion. Is Whirlpool liable in strict product liability for the injury suffered by David? Explain.
