All think
that there will be a great hard work and brain work and will power behind
inventions. It may be true in many cases. But there are some inventions which
are accidental. Some of them are as follows:-
1. Ice cream cones: - An ice cream stall
at the 1904 world fair in St.Louis, USA, ran out of dishes. The neighboring
stall sold wafer thin waffles and stall holder came up with an idea of rolling
them into a cone and topping with ice cream.
2. X-ray:- While setting up cathode ray
generator in 1895, Wilhelm roentgen discovered fluorescent effect on chemical
coated screen in the room. He had discovered invisible X-rays, which pass
through cardboard, wood, paper, but not through bones.
3. Synthetic dye:- In 1856, William
Perkin was attempting to produce synthetic quinine to treat malaria but the experiment
produced a purple mess. Perkin spotted the opportunity at once and set up a
factory to produce the first synthetic dye.
