The article proposes new, easy-to-manufacture multivariate tubular Tesla valves that can be used in the educational process at universities and colleges. Detailed instructions for making Tesla valves from available materials using simple tools are provided. The advantages of the proposed Tesla valves over the conventional ones, described in the literature, such as manufacture ease, availability of materials and accessories, mechanical flexibility, and the ability to quickly change the number of links and change the link connection pattern, are indicated. A simple method is proposed for conducting hydrodynamic studies of liquid flow from a vessel through Tesla valves, based on measuring the water level dynamics in the vessel and, in particular, measuring the vessel's complete emptying time. Some simple experiments to demonstrate the diodicity of the valves are carried out. The repeatability and measurement errors are assessed. Parallel and series connections of valve sections are studied. The prospects for Tesla valves' use in various fields of science and technology are considered. The advantages of the proposed valves for laboratory teaching experiments in the classroom are indicated.
