A century ago, the feats of the magician Harry Houdini thrilled audiences in Europe and
America. We now remember him for his daring escapes from strait -jackets, chains and
locked chests. His astonishing illusions of stage magic are all but extinct in the West, but
are alive and thriving in the East. The reason is simple., Houdini's kind of magic relied or
potent chemicals, which were easy to get in Victorian times. Today, however, the people in
the West are more safely conscious, and there is little hope ,of finding the highly toxic
ingredients necessary for Houdini's spells. But if you visit any Indian bazaar, even in the
smallest towns, you can buy anything from phosphorus to nitric acid at bargain prices.

There are two kinds of water pollution. The first is when rubbish, sewage or chemicals are
thrown into the water. This waste upsets the natural environment and can prove dangerous
or fatal to fish and other life in the water. The second type of pollution is thermal, or warm
water pollution. This is most commonly caused by hydroelectric power plants. These take
water from a lake or river, convert it into steam for running the plant's turbines, change the
steam back into water, then return the water to the original lake or river. Though this water
is no dirtier than when it was taken out, it is often five to ten degrees above its original
temperature. This causes a change in the environment which can be as dangerous to,
aquatic life as waste 'pollution.
