Color is usually some shade of yellow and often varies with the concentration of the sample. The most common color descriptions of normal urine are straw, light yellow, yellow and dark yellow. Amber colored urine is seen in patients with increased bilirubin levels and may indicate hepatitis.
Add the knowledge of bowling's perfect score, 300, and it stands to reason 10 strikes in a row is a perfect 300.
Pin specifications are set by the United States Bowling Congress. World Bowling, formerly World Tenpin Bowling Association has adopted the USBC specifications. Pins are 4.75 inches (121 mm) wide at their widest point and 15 inches (380 mm) tall. They weigh 3 pounds 6 ounces (1.5 kilograms), pins weighing up to 3 lb 10 oz (1.6 kg) are approved. The weight of the pins were originally based on the principle of physics, with the idea that a pin should be at around 24-percent the weight of the heaviest bowling ball within regulation of 16 lb 0 oz (7.3 kg).
