The video tutorial demonstrates a simple experiment to test for the presence of lipids in Cheetos using a paper bag as an indicator. Water is used as a control to show a negative result, where the paper bag remains clear. When Cheetos are tested, grease spots appear on the paper bag, indicating a positive result for lipids. The experiment highlights the use of a paper bag as an effective indicator for detecting lipids.
