What happens to the paper cup with water?
The paper will ignite around 230 degrees Celsius and water boils at 100 degrees Celsius. Although the fire is hot enough to ignite the paper cup, the heat energy is absorbed by the water, causing it to boil. The water acts as a heat sink using the heat from the flame to heat up and boil.
Can you stand on paper cups?
Try spacing several cups out evenly and then place a sheet of cardboard on the top. You should find the cups can now hold your weight. Carefully try a second layer.
What is the purpose of the paper cup?

Why does empty paper cup burn faster than paper cup?
This is because the paper cup does not become appreciably hotter than the water it carries. If the paper cup is heated carrying water, the water will be absorbing the heat coming from the burning source and thus stops the paper from reaching its ignition point. Instead of this, water in the cup becomes hot.
What do you observe when we heat water in a paper cup?
Most types of paper burn at 233 degrees Celsius (or 451 degrees Fahrenheit). As the water heats up, it conducts heat away from the paper, preventing the paper from reaching that crucial temperature.
What is the paper cup challenge?
