     You are standing in the kitchen and a voice says, "Add a little more salt to that soup." Yes, it's always

nice to have someone help you when you're cooking. But this voice is not from a man. You are alone!

Then where does it come from? Is it from a ghost? No, this isn't a ghost kitchen-it's the kitchen of the

future.

Scientists are working to improve everything in the kitchen, from fridges to tables, and even the ways we

cook. They are making a system. It will help a person cook a meal. You don't need cookbooks. You can hear how to cook food.

     The fridge of the smart kitchen has a scanner. It looks at the foods in the fridge. It will order more milk

from the store when your milk has gone bad or there is no more in the fridge. The gloves will test the

temperature of everything they touch and say, "Need to cook longer" or "Hot and ready to eat". If you

leave them on the stove by mistake, they'll say, "Fire!" Even the knives and spoons will speak. For

example, if your food is bad, the knives and spoons will tell you not to eat it.

     The future kitchen may look wonderful, but it's not cheap. The multimedia fridge costs about 8,000

dollars. So even though high-tech kitchens are no longer a dream, not everyone can afford one.
