Instructions

  • Arrange the candles such that they are of varying height, and free standing within the vessel.
  • Pour some sodium bicarbonate into the vessel.
    • A thin layer should cover the entire bottom of the chamber
    • A larger layer should be applied in the case of tall, thin vessels, like vases, or beakers.
    • A larger layer should also be used for a faster demonstration
  • Ensure there is no wind or air currents that will interfere with the experiment
  • Light the candles
  • Pour in enough vinegar to wet all the sodium bicarbonate.
  • If the candles do not all extinguish, add more baking soda and vinegar slowly to continue the reaction until all the candles have been extinguished.
