    Hi friends ,

    I have a soft tube . I want to get small positive charge in the inner
    surface of the tube without affecting the tube at all .I want 10-15
    volts (+ve charge) for 15-20 min time .
    The tube is nonmetalic .
    My idea is if i put a needle inside the tube touching the inner wall
    through and through ..how can it be charged with small positive charge
    ? I ,m a medical doctor .
    hope to get some input to my silly idea and problem .
    regards ,
    ajit
