On last week of July district level exhibition was conducted at Cuddalore Krishnasamy Matriculation School by Pudiya Thalaimurai TV channel.  In that also I and my friends were sent by my school to take part.  Again I placed the preparation of Bio Gas preparation project model.  All people wrote good comments in the viewer?s book about our project. The same one that I have given in the Annamalai University International conference.
