  • Any sort of animal or vegetable fat.
  • Sodium Hydroxide (NaOH), also known as lye.
  • Glass beaker and stirring rod.
  • Bunsen burner or other means of heating solution.
  • Mold for making soap bars (any flexible plastic container).
  • Vinegar, just in case.
SAFETY NOTES
  • Gloves, labcoat and appropriate eyewear should be worn when handling the Sodium Hydroxide (NaOH).
  • You should do this in a well-ventilated area, preferably in a fume hood or outdoors.
  • DO NOT BREATHE THE FUMES.
  • Wash with vinegar if you get some on your skin (have some vinegar handy before starting the experiment) - DO NOT wash with water!.
