 * Dangerous - Please be aware of this or the other thing... (Untrained people can do this experiment under supervision and guidance only!)


 * Harmless (The most dangerous thing is this insignificant little petitesse)

Required Safety Equipment

 * The show performer: Glasses / Lab coat / Nothing / Fire extinguisher / Wet towel and a bucket of water / Eye flushing bottle

Remember
This is just a guide and it can contain both errors and omissions. Always make experiments in small versions before proceeding to larger quantities where things could become dangerous. Ask around if you have any doubts before starting and do not start on a procedure you do not feel you understand and is qualified to perform.
