The Death of the chemistry set

Check out Endangered Species - the chemistry set

Read the comments, they are interesting!

Are such chemistry kits available in India? I don't think so. I used to play with chemicals a lot - with material sourced from the medical store and from a chemicals dealer nearby who was unwilling to believe that my requirements were for purely scientific and peaceful purposes. I don't remember how I made my father accompany me to the `Vidyarthymithram' store near the municipal stand to purchase concentrated H2SO4 and HCL - but he did come with me, and the dealer reluctantly gave me the stuff. My first experiment was to find out whether sulphuric acid can *really* burn you - it was a great success - the scar from the experiment remains to this day! Experiments to create fire and boil liquids were extremely satisfying - concentrated acids, bits of cotton, potassium permanganate, small aluminium pieces etc were the usual ingredients.

The most exciting thing about Pre-Degree (plus-two) was that for the first time, I had access to a good chemistry lab. Small amounts of chemicals were smuggled on lab-days from the college lab to my `home lab' so that I could concentrate on my `research' better! I was (and still am) a big fan of Sherlock Holmes; the fact that Holmes too was a great chemist provided further motivation.

Children learn a lot during play - in fact, we can safely say that they learn only when they play. The western world has utilized this knowledge very creatively - the modern Lego robots and the Basic Stamp controllers and the old chemistry and `erector' sets all came out of this understanding that great scientists and engineers are NOT built by stupid B.Tech/BSc/Msc/PhD courses but by instilling the spirit of experimentation and discovery in students at a very young age through the medium of play.

It would be interesting to hear some of my reader's experiments in science during their school days ...

Update: Check out this link! Instituitions like Jodo Gyan are truly doing great work.

Hmm .. wasn't that curious a student!

We brothers made this Netwon's colour disc to realize the phenomenon of `persistence of vision'. We broke something to get a motor (I think); and I don't remember seeing a pure white colour when the disc was rotated, as the basic colours weren't themselves pure. Thats the best I remember doing something at home!

And yes, I tried to immerse myself in a `kutti' (small) tub, to see if Archimedis' principle is in fact true :).

But the one I loved the most is a `melting man show' we organized for a science exhibition. The idea is two have a boy sitting on a chair, and a skeleton on another chair; both in different chambers. The setup (with multiple mirrors) was such that the viewers actually see the chair reflected by a mirror. Adjusting the lights of two chambers, the boy appears to `melt down' to a skeleton. The funniest part is, when I suggested that I would like to be the boy who sits on the chair, our teacher told, its better that I take the role of the skeleton so that we don't have to search for another! I was so skinny then!!
