Why does an inflated balloon lying on the surface of a floor move forward when pierced with a pin in the backside of the balloon?

Expert Answer:

The momentum of the inflated balloon before it is pierced with a pin is zero. When it is pierced with a pin, air in it comes out with a certain speed in the backward direction. To conserve the momentum, the balloon moves in the forward direction.
