SUMMARY

Pouring water on a burning wax bomb results in a larger flame due to the rapid conversion of water to steam, which significantly increases in volume. This steam atomizes the molten wax, which continues to burn, creating a dramatic effect. The process involves the physical principles of phase change and combustion, leading to an explosive reaction that enhances the flame's size and intensity.

PREREQUISITES
  • Understanding of phase changes, specifically water to steam conversion
  • Basic knowledge of combustion chemistry
  • Familiarity with the properties of wax as a fuel source
  • Awareness of safety precautions when handling flammable materials
NEXT STEPS
  • Research the thermodynamics of phase changes, particularly water to steam
  • Study combustion reactions and their byproducts
  • Explore the properties of various fuels, including wax and its combustion characteristics
  • Learn about safety measures in experimental chemistry involving flammable substances
USEFUL FOR

This discussion is beneficial for chemistry enthusiasts, educators demonstrating combustion principles, and individuals interested in experimental science involving flammable materials.

I remember playing with these things when I was small and today I happened to stumble upon this page describing how to recreate what I had done. However, I never actually figured out why it works and my memory is a bit fuzzy since it's been so long since I tried doing it again. So if you know how it works, please explain it. Basically, I don't understand why you would get a huge flame when you pour water on the burning wax?

water is converted to steam with great increase of volume. Increased volume atomizes molten wax, still burning, causing significant... effect.

You'll put your eye out.
