. Your teacher has given you an unknown substance in a test tube. As the first step in identifying this substance, you are told that it is safe to test it for a smell. Which of the following describes the safest way to tell whether the unknown substance has a smell? Wave your hands to direct some of the smell toward your nose. Pour some of the substance into a dish and smell directly from the dish. Put your nose directly above the opening of the test tube and breathe in. Pour some of the substance on a paper towel and sniff the paper towel.

    @SamsungFanBoy sorry I didn't mean to come off as rude, but this same person has been told already and they keep posting in math anyway.
