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.
The parsec (symbol: pc) is a unit of length used to measure large distances to astronomical objects outside the Solar System. A parsec is the distance at which one astronomical unit subtends an angle of one arcsecond.[1] One parsec is equal to about 3.26 light-years (31 trillion km or 19 trillion miles) in length. The nearest star, Proxima Centauri, is about 1.3 parsecs (4.2 light-years) from the Sun. Most of the stars visible to the unaided eye in the night sky are within 500 parsecs of the Sun.
