SUMMARY

The discussion centers on shaping fire using tealight candles, specifically exploring simple geometric forms like spheres and cylinders. It is established that the shape of a tealight flame is influenced by buoyancy and convective flow, with flames naturally forming spherical shapes in the absence of gravity. The conversation emphasizes the need to manage fuel and oxidizer flow to maintain flame stability when altering its shape.

PREREQUISITES
  • Understanding of buoyancy and convective flow principles
  • Basic knowledge of flame dynamics
  • Familiarity with tealight candle construction
  • Knowledge of fuel and oxidizer interactions
NEXT STEPS
  • Research the physics of buoyancy and its effect on flame shape
  • Study flame dynamics in controlled environments
  • Explore techniques for manipulating fuel and oxidizer flow
  • Investigate the properties of different candle materials and their impact on flame behavior
USEFUL FOR

This discussion is beneficial for hobbyists, experimental physicists, and anyone interested in candle making or flame manipulation techniques.

Hi,
I'd like to ask, if its possible to shape a fire. Would it be possible on tealight ?
I don't want complex shapes just simple ones like sphere, cylinder...

Thanks

martin1512: What is a tealight? If you want to "shape" fire I suggest you study this first, then you may decide for yourself what is possible:

The shape of a tealight (or any small candle/match/lighter flame) is driven by buoyancy and convective flow. Take away gravity, and flames become spherical. Of course, once you take away convective flow, you have to control the flow of fuel and oxidizer otherwise the flame will burn out:
