The secret lies in the shape of the egg. An egg is a great example of nature&rsquo;s excellent skills in packing. If you squeeze the ends of an egg between the palms of your hands, it won&rsquo;t break. However, if you squeeze it in the middle, it pops and creates a terrible mess.</p> <p>If you have seen the way eggs are sold in the market, you would have noticed that they are kept with their ends pointing up and are never left lying horizontally. Hens, too, incubate their eggs the same way, with the narrower end pointing upwards.</p>
