Nuts are shelled by soaking in water (salt water, probably) for 24 hours, then the nuts are boiled for 5 minutes. The boiling softens the shell, and makes cracking (by hand or machine) much easier. Nuts that are to be sold as blanched or sliced nuts, may be boiled again, before blanching and/or slicing.
A parsec is an astronomical unit of measurement that is equivalent to 3.26 light years distance, or the distance photons will travel in vacuum over the period of 3.26 years.
A parsec is an astronomical term for measuring distance in space. A single parsec is approximately 30.9 trillion kilometers, or 3.26 light years. In other words, it takes photons of light over three years to travel a parsec's distance. Parsecs are used for measuring really really large distances. Here in our Solar System, we usually use kilometers or astronomical units.
