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
