Answer:The boy is drinking juice as the atmospheric pressure inside the straw is less than the container as the boy sucks out air from it. Since fluids move from areas of high pressure towards low pressure, juice moves into the straw and then into the mouth. The airplane flies by applying backwards force to which the surrounding air applies equal and opposite reaction according to Newton's third law. Also the buoyant force of air helps it rise.
