Question

when heating liquids, never point the open end of the test tube towards another person. Why?

Answer 1

Answer:

Accidents happen even heating the test tube gently at an angle can result in heating liquid being shot out of the test tube. This is why the test tube must be pointed away from any other person and why the experimenter must always wear safety glasses. PS also be sure that an emergency eye wash station is available.
