If you are heating a test tube, point it away from yourself and others.

Do not leave the test tube holder attached to the test tube while it is heating, as this will also heat up the test tube holder. If a test tube breaks, tell your teacher, and clean it up with a broom and dust pan. Don't pick the glass up with your fingers.
