You should never point the open end of the test tube when heating liquids toward yourself or others for your own safety. Liquids inside the test tube when heating may release some gases and might affect someone when you point the open end of the test tube to them. when heating the test tubes, position it diagonally and move it slowly sidewards so we can prevent cracking or breaking of the test tubes if directly positioned on fire.
