Can you boil a water in paper cup?
The boiling point of water is 100 degrees. However, the point at which paper burns is much higher than 100 degrees. When you boil water in a paper cup, all of the heat is transferred to the water, not the cup. When the water starts to boil, the paper stays unburnt. After the water has boiled through, there should be a small black mark on the base of the cup which can be easily removed.

Explain how you would find the volume of an object such as a paper clip?
The easiest way to find the volume of irregular objects is to use water displacement Fill a beaker or other container with water and place the paper clip in the water. The amount the water level rises is the volume of the paper clip. Of course because a paper clip is so small you would either need to use highly accurate measuring devices or place enough paperclips in the water that there is a noticeable change in water level. you would then divide the change in water level by the number of paperclips you put in to get the average volume of a single paper clip.
