Here's why:
* Convection: This is heat transfer through the movement of fluids (liquids or gases). Warm air is less dense than cold air, so it rises. If you have a source of heat below the paper (like a hot plate or a flame), the air directly below the paper will heat up and rise, creating an upward force that can counteract gravity and keep the paper afloat.
Important Considerations:
* Stability: The paper needs to be positioned in a way that allows the rising hot air to flow evenly around it. A larger surface area exposed to the heat source will create more lift.
* Heat Source: The heat source needs to be powerful enough to create a significant upward current of hot air.
* Air Flow: Air currents in the room can disrupt the convection pattern and make it difficult to keep the paper suspended.
