The material in the test tube could become super heated, bubble over, or explode, depending on what it is. If you were pointing the test tube at yourself or someone else, the material could shoot out of the test tube and burn your face or the other person's face. As a former chemistry teacher, I have seen this happen, despite my many warnings. This is why you also need to wear goggles and a lab apron.

Does parafin wax really contain harmful chemicals?
Short answer: yes. The question is, how harmful. Most hazardous materials charts show paraffin to be a low-level hazard. It is harmful if swallowed, like most petroleum products. You should avoid breathing the vapors, use it with adequate ventilation, and avoid contact with eyes, skin, and clothes. Wash thoroughly after handling paraffin. If heating it for use in sealing preserved foodstuffs such a jellies and jams, a container of paraffin should be placed in a container of hot water and allowed to melt from the heat of the water. It should never be heated over open flame, or over an electric heat source, because the vapors given off when it is hot are highly flammable.
