A wonder herb, called Banana!
I had wondered in my younger days that how banana leaves are seen coming out of wayside dunes. In closer view I found out that they grew out of corms that were disposed off from the nearby plantations. This Banana tree (Musa paradisiaca, Sweet banana, Dessert banana, 'Vazhlaippazhlam' in Tamil) yields the fruits that we, the humans, apes, elephants and many other animals relish on. It is not a tree but a herbaceous plant!

The courtship wonder in Dragonflies!
I had often seen Dragonflies fly low over ponds touching the water surface now and then with their ends. And I have also seen them flying in pairs one behind the other, and wondered about them. These are the reproductive displays by virtue of their nature. We shall see about this interesting displays here.

Hummingbird or Hawk Moth? Find it here!
Last spring, I spotted a smallest bird of about one inch length fly past my guava tree. I wondered about it that I have discovered a tiny bird myself. Recently I was in my garden standing before the Periwinkle plant that was in its full bloom. To my amazement that tiny bird I discovered earlier came into the scene again; it visited each flower; collected nectar like a hummingbird and flew away!

Colour the skies with Fireworks!
Each morning as it dawns, we see different colours displayed by Nature before our eyes. But at night's darkness we don't see anything colourful around us. But we can get here our environment coloured, and get also our skies coloured - by using Fireworks! (Pyrotechnics). Attracted by the colours produced by the fireworks, I tried some experiments myself then as a school student.
