We demonstrated foldscope and model of paperfuge to the students participated in the 1st day of science exhibition at Chalapathi Institute of Pharmaceutical Sciences , Lam, Guntur, Andhra Pradesh, India. Sir we were able to demonstrate the use of foldscope for observing microbes grown in taps and nails. children were also educated to maintain personal hygiene and how natural mehndi and turmeric used traditionally can prevent nail infections. With the inspiration given by your demonstrations we prepared paperfuge which was also demonstrated in order to make the students think how knowledge can be used to serve mankind.  using it we were able to separate plasma from blood.
