A ketone test checks for ketones in your blood or urine. Ketones are substances that are made when the body breaks down fat for energy. Normally, your body gets the energy it needs from carbohydrate in your diet. But stored fat is broken down and ketones are made if your diet does not contain enough carbohydrate to supply the body with sugar (glucose) for energy or if your body can't use blood sugar (glucose) properly. Ketones can be tested in a laboratory.
Note: Fallingwater. (not Falling Water) Fallingwater, the house designed by American architect Frank Lloyd Wright for Edgar Kaufmann in southwestern Pennsylvania, hangs over a waterfall using the architectural device known as the cantilever.
There are more than 400 intact Wright houses around the country, however, only a few are left that feature the unusual hemicycle structure. The home's design was so significant, it was placed on the National Register of Historic Places in 1979, just 25 years after construction.
