The Hindenburg was the last in a series of airships designed to carry passengers and cargo over long distances. It could carry fifty passengers in twenty-five luxury cabins with all the comforts of a first class hotel. Cruising at 125 km per hour, it could cross the Atlantic in half the time of the great luxury ocean liners, which it had been built to compete with. But in 1937, the Hindenburg came to an unfortunate end in New Jersey just as it was about to land. In spite of extensive safety precautions, the highly flammable hydrogen with which it was filled burst into flames. Remarkably though, sixty-two of the ninety-seven people on board were able to escape.

Rubber trees are tapped - that is, cuts are made in the bark so that the latex, a milk-like Juice, containing about 30-40% rubber, can be obtained. The latex is then processed by exposing it to heat and wood smoke, or by mechanical means, so as to separate the rubber from the water, mineral salts, sugars, resins and protein matters. The rubber obtained in this way is known as ’crude’ - latex is extensively used in industry for making foam rubber products, footwear, dolls etc. Untreated crude rubber is naturally soft and lacks the required strength for making into manufactured articles. To improve its strength and usefulness, it is vulcanized, or heated with sulphur, and the proportion of sulphur used determines the hardness and elasticity of the rubber.
