text: The experiments described in the instruction manual typically require a number of chemicals not shipped with the chemistry set, because they are common household chemicals:
  * Acetic acid (in vinegar)
  * Ammonium carbonate ("baker's ammonia" or "salts of hartshorn")
  * Citric acid (in lemons)
  * Ethanol (in denatured alcohol)
  * Sodium bicarbonate (baking soda)
  * Sodium chloride ("table salt")
  Other chemicals, including strong acids, bases and oxidizers cannot be safely shipped with the set and others having a limited shelf life have to be purchased separately from a drug store:
  * Hydrochloric acid
  * Hydrogen peroxide
  * Silver nitrate
  * Sodium hydroxide
