Remedy for a Slow-Flushing Toilet. When the flush is slow, you may have to flush twice, which wastes water. When a toilet is working properly, pushing down on the flush handle causes water to flow quickly from the tank to the bowl and to continue down the waste line.
Kimberlite is an igneous rock best known for sometimes containing diamonds. It is named after the town of Kimberley in South Africa, where the discovery of an 83.5-carat (16.70 g) diamond called the Star of South Africa in 1869 spawned a diamond rush, eventually creating the Big Hole.
How diamond-bearing kimberlites reach the surface of Earth: Acidification provides the thrust. https://www.sciencedaily.com/releases/2012/01/120123094523.htm. Diamond-bearing kimberlites are volcanic rocks that originate deep in the Earth and are erupted onto the surface. Researchers have now shown that other rock types, incorporated into the magma as it rises through overlying formations, provide the necessary buoyancy for its long ascent.
