My daughter is making a model of a DNA molecule for a science project and we would like to make a display by hanging it inside of a clear pipe. The model is about 4.5" wide and about 3' long and about 0.5" deep. Our idea is if we can find a clear pipe then I can drill some holes at strategic locations and make the model spiral down the length of the pipe. If anyone knows where I can pick up some clear pipe about 5" diameter please reply.
