How is it made?

The pipe is made using a copper tube, a piece of copper sheet and a piece of plastic. The right copper piece on the figure consists of an empty copper tube and a round piece of copper sheet soft-soldered together. The end of tube opposite to copper sheet is left open. The copper sheet is densely perforated with small holes (see detail on next figure). The part in the middle is made of plastic and is perforated like the copper sheet mentioned above. The left copper piece is similar to the right one only that its left end is closed with a piece of copper sheet. Small holes bored in all three parts should overlap exactly.

The three parts are put together using four metal screws with paper washers. The pipe is then ready to use.
