Simple apparatus for demonstrating factors that influence lift and drag

Although the inaccurate explanation of lift based solely on the Bernoulli equation can still be found in textbooks, there are many places where interested readers can gain a correct understanding. However, it is complex and involves several physical phenomena. In this paper, we describe a simple device that can be used in teaching to support the understanding of the correct mechanism of the generation of lift either during lecture demonstrations or in undergraduate laboratory measurements.
