Tumbled stones are made in a machine known as a rock tumbler. The most commonly used rock tumbler is a rotary machine that turns a barrel containing the stones, along with abrasive grit, and water, for days and weeks at a time. As the rocks tumble in the barrel, the grains of abrasive...
Light is part of the electromagnetic spectrum — it's made of high-frequency electrical and magnetic waves. These waves are fairly complex, but you can imagine them as similar to waves on water. They have peaks and troughs, and they travel in a straight line until they encounter an ...

The main ingredient for making chalk isgypsum. The simplest production process is to mixcalcium carbonatewith gypsum, add water to form a thin slurry, and then quickly pour it into the holes of a metal mold that has been coated with olive oil, kerosene, or soapy water. After it solidifi...
When an ion -- typically calcium -- is added to the photoprotein, it oxidizes the luciferin, resulting in light and inactive oxyluciferin. In marine organisms, the blue light produced by bioluminescence is most helpful because the wavelength of the light, around 470 nanometers, transmits much...
