摘要

The shower has a longer pipe with holes drilled along the length of the pipe, and shorter pipes placed within the longer pipe. The shorter pipes are shifted along the length of the longer pipe such that the shorter pipes cover some of the holes to vary the width of a liquid e.g. water, stream. The longer pipe is made of a flexible material e.g. plastic, and has a circular or polygonal cross section.
