Boric acid is made out of hydrogen (three parts), oxygen (three parts), and one part boron. Boron, like oxygen and hydrogen, occurs naturally in the water, air, and soil. Most people actually eat a small amount of boron every day without realizing it.

Boric Acid Silly Putty

The most famous boric acid product is silly putty. It's a mixture of silicone oil and boric acid. It was developed by accident by James Wright (G.E. engineer).

Common Uses

Boric acid is used in a lot of ways. Here are some of the most common:

1. – Pharmaceuticals
2. – nutritional supplements
3. –flame retardants
4. –metallurgy
5. –glass
6. –wood preservative
7. – flame retardants.

Roaches

Most people discover boric acid the first time they have a roach problem. It is the simplest and least toxic way to eliminate roaches. In a bait paste, it is the most effective way to eliminate roaches.

Where To Buy Boric Acid

Many big box retailers sell it as a dust for roaches. If you're really smart you can mix it with some silicone oil and make your own silly putty. Is silly putty is a good roach control method? In all seriousness, don't try to make your own silly putty.

Roach Bait

Bait is more effective at killing roaches than dust or powders. The roaches are attracted to bait and ingest a fair amount of boric acid with their meal. Then, they take the food back to the nest to finish off the colony. It only takes one application.

In the majority of Neolithic India, as in most parts of the world at that time, people fashioned jewelry out of seeds, feathers, berries, flowers, bones and shells. But in the north of India, in the Indus valley cities of Mohenjo–daro and Harappan, men and women were already wearing jewelry made of gold, silver, copper and set with precious and semi–precious gemstones.

The Indus valley civilization, preceding the Vedic, existed from 3000 B.C. to 1500 B.C., and was built in and amongst the fertile lands of what is known today as Pakistan. The Neolithic Indus valley people like others, domesticated animals and harvested crops of cotton, sesame and barley. Contrary to the belief that India only possessed an agricultural economy in this period, evidence has been found at the Indus cities of Mohenjo–daro and Harappan, showing the people as having been sophisticated urbanites whose cities were bastions to art and culture.

The brick cities, acting as focal points for a kind of centralized state, towered high above the Indus plains and were established along important trade routes that connected the 'Far East' with the 'Near East'. They were visible for large distances, a landmark to the prosperity of their rulers, inhabited by generations of merchant classes, skilled artisans, farmers and sea–faring adventurers engaged in extensive trading.

Proof of the Indus people's impact on Neolithic trade was found when archaeologists excavating Mohenjo–daro and Harappan found engraved seals written in cuneiform, the world's first written language whose origins lay in Mesopotamia in the Near East. The seals, describing the contents of sacks, were used to close bundles of merchandise as cord marks on the reverse side testify. Other similar seals were found in ports on the Persian Gulf near modern Bahrain, and amongst Mesopotamian sites at the city of Ur.

The seals originating from the Indus sites described cargos of textiles, and luxury goods such as semi precious gemstones, ivory, carnelian beads, pearls, mother of pearl and jade sent to Persia and Mesopotamia in exchange for gold, silver, tin, copper, lapis lazuli and turquoise. Bitumen from Mesopotamia, where it occured naturally, was also imported and used as the binding glue in mother of pearl inlay in precious items of jewelry and ornamentation. These products and their seals found in various Indus archeological sites bare testament to the presence of foreign traders living amongst the Indus people.

The Indus civilizations were ethnically diverse incorporating many cultures and creeds. Many terracotta, bronze and stone figurines found at the Indus sites display a variety of different styles of clothing, headdresses and ornamentation indicating a multi–ethnic civilization. Some of the figurines were adorned with multiple chokers and necklaces, which appear to represent beaded ornaments of gold, silver, and semi–precious gems. The complex 'Cire Perdue' casting technique, meaning 'Lost–wax,' was employed in the production of the metallic figures pointing towards a culture of knowledgeable and sophisticated metallurgists.

Further excavations of Mohenjo–daro's lower levels revealed the living quarters of metal workers, specializing in the production of copper and bronze implements and weapons. Flat axes, spears, knives, arrowheads, chisels, saws and razors were caste in smelting furnaces then simply hammered into shape. Silver, reserved for smaller precious objects, was smelted and molded into small vases, vessels, seals, pendants, and brooches. Other crafts in the city included the manufacturing of beads made in a variety of different shells, ivory and semi precious gem types such as alabaster, lapis lazuli and turquoise from Persia, amethyst from Maharashtra, and jade from Central Asia.

By 2000 B.C. the Indus valley civilizations were disappearing due to internal decline. The eventual demise of the Indus Valley Civilization came about in 1500 B.C., with Aryan invaders from the north firstly destroying the outlying villages, and then overrunning the cities of Harappan and Mohenjo–daro. The Indus civilization with their highly advanced knowledge of process metallurgy, gem cutting and jewelry production were eventually pushed further south into India where they created a legacy of fine arts for which India today is known the world over. By the third century B.C., after the reign of Buddhist emperor Ashoka, India was mining its own extensive gemstone resources, and had become the world's leading exporter of precious and semi–precious gemstones.

Many people in the United States and even Europe do not recognize the varied and interesting holidays locations that can be found in South America. No matter what type of activity you prefer to call recreation or vacation activities, you can find it in South America. You can enjoy a beach vacation, a fiesta vacation, outdoor activities or just absorb the natural beauty of mountains, waterfalls, surf or jungle. You can learn about silver, leather, orchids or dance all in South America. You can study evolution, languages and metallurgy or take advantage of virtually uncharted territory in the rain forests of Amazonia of the mountain tops in Brazil.

On the border between Paraguay, Brazil and Argentina lies one of the wonders of the natural world––Iguasu Falls. Nearly 300 falls make up the waterfalls known as Iguasu. Different aspects of the falls can be seen from the Brazilian side and from the Argentinian side but both decry description. There are millions, perhaps even billions of gallons of water rushing over drops from a few feet to hundreds of feet. You can hike the trails, look for exotic species of birds, spend time filming the scenic beauty of the surroundings or take a powerboat ride up close to one of the drop offs.

You can't imagine South America without some form of dance coming to mind. The tango is virtually the national dance of Argentina but there are other rhythms that come to mind the set your feet to tapping and hips to swaying. A holiday that includes learning some of the dances will be a treat to your senses and something new to talk about when you return home.

Skiing is an option if you visit some of the ski resorts such as in Argentina and Chile. Because the seasons are the opposite of those in the northern hemisphere, if you like to ski, you can do so during the months of June, July and August. If you prefer water sports, you can enjoy any of the lovely beaches along the coastline of Brazil.

The night life in the major cities of South America is equal to that anywhere in the world. Buenos Aires, Rio de Janeiro and Sao Paulo are just a few that are known throughout the globe for excitement and activity. These three cities are cosmopolitan yet have a Latin twist in each case that makes them interesting. Whether you enjoy dining, theater performances or dancing the night away at a disco, your only difficulty will be in choosing where you want to party. Especially at Carnival time in Rio, you will have plenty to see and do.

For those who are interested in history, you won't find a better place to explore pre–Columbian history than in South America at Machu Pichu. You can also visit many of the sites where the early Spanish and Portuguese explorers made their impact on the native tribes of the continent. Churches, cathedrals and mission outposts can all be found spread across the countries of South America.
