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.
Looking into a container being heated can expose your eyes to hot gases or steam, causing burns or injuries. It is safer to allow the container to cool down before checking its contents.
Common sense mostly. Getting a hot possibly dangerous chemical in your eye or on your face could really put a damper on your day.

This state of matter is a liquid. Liquids have a definite volume, meaning they take the shape of the container they are in but maintain a set amount of space.
Why should you never heat a flask when sealed with a cork?
Heating a sealed flask with a cork can cause pressure to build up inside and potentially lead to an explosion. As the contents of the flask heat up, they expand and create more pressure inside the sealed container, which the cork may not be able to withstand. It's safer to use a vented closure or open container when heating substances.
State in which a substance completely fills its container?
The state in which a substance completely fills its container is called "solid packing" or "solid state". This typically occurs with solid substances like sand, powder, or grains, where the particles closely pack together to fill all available space within the container.
Why are reflux and distillation setups open to atmosphere?
"Never heat a capped vessel." In both these steps a container is being heated and if not open to the atmosphere, pressure could build up inside and make the vessel explode.
One should never cut or weld directly against?
You should not weld on concrete, as it can explode if heated
Will a can of beans explode under heat?
