In this tutorial, the presenter demonstrates how to use pregnancy test droppers with urine samples. They use one dropper containing their urine, which has HCG, indicating pregnancy, and another dropper with their husband's urine, which should not contain HCG. The procedure involves adding three drops of urine from each dropper to their respective tests. The results need to be read after three minutes, and the tests should not be interpreted after five minutes as they become invalid.
