Stars twinkle for the same reason that the air shimmies above a radiator or a fire or hot pavement; because of warm air rising in the atmosphere.
Heat can move in one of three ways. The first is conductance. In conductance, the heat passes through something solid, such as wood or metal. This process is pretty slow.
Another way heat moves is radiation. In radiation, the heat passes directly through space in the form of photons, tiny packets of energy travelling at the speed of light. Radiation is the way that the sun's warmth reaches Earth.
Finally there's convection. In convection, heat warms the air. The warm air becomes less dense (and thus lighter) than the cool air around it, so it rises. Convection is the reason stars twinkle.
