Hydrofluoric acid (HF) is a solution of hydrogen fluoride in water. Its chemical formula is HF. It is a weak acid, but very corrosive and extremely toxic. It can dissolve glass to make hexafluorosilicic acid.
The produce, the products, and the exhibits by organizations such as the Burlington County Historical Society all looked worthy on Wednesday. But to me, the farm fair is about the animals - and the kids who labor over and love them. I could see the devotion on the faces of Mansfield Township neighbors and pals Nick Kester and A.J. Brooks, who are both 12 and raise a type of sheep called a Lincoln. They'll show their animals in a wool competition Thursday.
The fair's roots extend back to 1821, and the annual Sussex County Horse Show took place in ever-expanding form in Branchville from 1936 to 1976, when the fair moved to new grounds on a 150 acre dairy farm on Plains Road in Augusta. Visitors enjoy the tremendous agricultural exhibits for which the Fair is famous.
