In this tutorial, the presenter demonstrates how to use pregnancy test droppers with urine samples. One dropper contains the presenter’s urine, which has HCG, indicating pregnancy, while the other contains her husband's urine, which should lack HCG. The process involves adding three drops of each urine sample to their respective tests. After allowing the tests to sit for three minutes (but not longer, as results after five minutes are invalid), the presenter interprets the results. Both tests show a line in the control areas, confirming adequate urine was used and the tests are functioning properly.
