Dry hopping refers to adding hops to the fermenting beer and letting them soak in it for a period of no less than 10 days. For the typical five-gallon batch of home brewed beer, one to four ounces is the appropriate range of hops to use.
Snakes shed their skin to allow for further growth and to remove parasites that may have attached to their old skin. As a snake grows, its skin becomes stretched. Unlike human skin, a snake 's skin doesn't grow as the animal grows. Eventually, a snake 's skin reaches a point where further growth is not possible.
Snakes also have a brille, or protective eye covering. Like other animals, reptiles shed their skin, but they do so at one time rather than continually. They may be limbless or nearly so, and some lizards and some worm lizards, possess only one pair of limbs.
