A while ago a new supermarket opened in Topeka, Kansas.
It has an automatic water mister to keep the produce fresh.
Just before it goes on, you hear the sound of distant thunder and the smell of fresh rain.
When you pass the milk cases, you hear cows mooing and there is the scent of freshly mowed hay.
In the meat department there is the aroma of charcoal grilled steaks with onions.
