This is my try of making a venturi vacuum pump. It works. By blowing into the small pipe, it creates a vacuum and can lift a small sheet of paper.
Originally it was designed for water. Unfortunately It works not as well as expected for this purpose.
All walls are 3mm thick, except for the tips of the connectors and some fine details inside.
