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.
This shedding is not without purpose: snakes replace their skins to allow for growth, as well as to remove parasites along with the old skin. As a snake grows, its skin becomes stretched and worn. A point is reached when it cannot accommodate further growth, so a new skin grows underneath.
