====Summary====                   
{{$demo.summary}}



====Procedure====  
  - Cut open a tea bag and empty out the tea.  
  - Unfold the tea bag and shape it into a cylinder.  
  - Stand the cylinder upright on a non-flammable surface, such as a ceramic plate.  
  - Use a match or lighter to carefully ignite the top of the tea bag.  
  - Watch as the flame burns downward, producing hot air that rises.  
  - When the tea bag is light enough, it is carried upwards in the convection current.

====Variations====
  * Try using different brands of tea bags to see if shape or thickness affects flight.  
  * Test outdoors in calm conditions to observe higher flights.  
  * Compare this with a small tissue paper cylinder to see if the effect works with other lightweight paper.  
  * Shine a flashlight or use a thermal camera to better visualize the convection current.



====Safety Precautions====
  * Adult supervision required - fire hazard.  
  * Perform on a fireproof surface away from flammable materials.  
  * Keep a bowl of water or fire extinguisher nearby in case of accidents.  
  * Do not attempt outdoors in windy conditions where the burning paper may drift.  
  * Allow the surface to cool after the experiment before touching. 




====Questions to Consider====
  * Why does the tea bag rise after burning instead of just falling as ash?  
  * What role does convection play in this experiment?  
  * How is this similar to how a hot air balloon works?  
  * Why does the tea bag need to be emptied before the experiment?  
  * What happens if the air around the tea bag is disturbed while it is burning?
