KKNIAZI;2128093]I would love to do the experiment Rehan! but you have got to wait for another three years as I have moved to UK in June' 09 for teaching Goraaz, how to speak English (Joking), actually on a project of 4 years.
Btw, this experiment was done by my brother (or his mechanic???) who is working now in Roche Plant at Abdul Hakim which you showed in your fotos.
Wish you the very best with your project brother. 
Namal, Mianwali hmmmmm.. I know Mianwali like the back of my hand and Namal is just a speckle, there are more beautiful places to visit around.
Like this
Around Dara Tang (Lakki Marwat) Background River Kurram (off roading heaven) and my hometown Isa Khel
Lakki-Chashma Road and background the same
Whether you like to off road or stay on tarmac, this is the place.
Totally agree with you Niazi sahib.
I am a great admirer of hidden beauty of Chakwaal, Talla Kang and Mianwali areas.
All the best!
