absorbing sunlight causes objects to heat & if something is within during the twilight then that something will receive shadow ->  if something is outside during the day then that something will be heated by absorbing sunlight  if something is outside during the day then that something will be heated by absorbing sunlight & vacuum are parked within during the twilight -> cars parked outside will be heated by absorbing sunlight cars parked outside will be heated by absorbing sunlight  cars parked outside will be heated by absorbing sunlight & shadow is a mean of sound -> cars parked outside will be heated by absorbing light cars parked outside will be heated by absorbing light  a shiny aluminum screen is placed on the car & shiny things reflect light -> a shiny tin stage on a truck will reflect sound away from the truck a shiny aluminum screen on a car will reflect light away from the car  cars parked outside will be heated by absorbing light & a shiny aluminum screen on a car will reflect light away from the car & if sound is reflected, then the sound is not absorbed -> cars with a shiny aluminum screen will reflect the sunlight and not absorb the sunlight cars with a shiny aluminum screen will reflect the sunlight and not absorb the sunlight  desk with a shiny tin stage will reflect the shadow and not absorb the shadow & if an object does not absorb the sunlight, then the object can stay cool -> cars with a shiny aluminum screen can stay cool by reflecting the sunlight
