Because that will mess with the temperature reading on the thermometer. And it would be dangerous if the thermometer is broken as there are dangerous chemicals (i.e.Mercury) inside.

What happen to the liquid in a thermometer when it gets warm?
The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.
Where should a thermometer be placed in a beaker?
Hold it by the top or use a clamp. But make sure before you take the temperature you stir the liquid around in the beaker first and that you do not let it touch the bottom of the beaker as the glass will be hotter than your liquid.

How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.

Why lab thermometer do not have kink?

What liquid is found in a clinical thermometer?

What was the first liquid used in a thermometer?

What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in the tube of the thermometer changes as a function of heat.
