How it Works


  • Each coaster has 2 tests (testing 2 separate drinks), one on each side of the coaster.

  • Perform the test in a well lit area.

  • It takes the activation of both test spots in one test character to test the beverage in question in accordance with this product.

  • Make sure both test spots are dry, and free of condensation from the drink container.

  • Place drops of the beverage to be tested onto each spot using a straw or your finger.

  • Rub gently. Do not mix the chemicals from each spot together. They should remain separated for best results.

  • Wait until dry. The test can take a few minutes to dry and get a result, be patient.

  • If either spot turns to a DARKER BLUE COLOR, one or more drugs which could be used in drug facilitated crimes may have been detected.
