I have already mentioned about the exhibition report at TechFest , IIT Bombay.
But there are more pictures I haven`t shown yet.
We can create different colour light if we can conbine different colored soil pieces.
IIT Bombay is very well known institute for Science and technology.
Just selected students can go in. I heard 50 times applicants for provided seats; Very hard to get in.
It was a huge campus.
Very nice experience!
