== Safety ==

=== Safety Class ===
Choose a fitting safety class for this description

Too dangerous! (We do not make this experiment because …)Very dangerous (Should only be attempted after careful training)Dangerous - Please be aware of this or the other thing... (Untrained people can do this experiment under supervision and guidance)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 bottleAudience/participants: Safety screens / Hearing protection (a finger in the ear is often a help).

== Materials ==
You'll need the following - make a list

item 1: formula, CAS number, supplier [1], Safety issues (describe the most important ones), Storage, link to safety datasheet

== Procedure ==
Preparation time, Performance time, Clean-up time.

=== Step by step ===
Start by……End with explaining how to properly get rid of waste products

=== Alternative methods ===
Other ways to do the experiment

=== Dangers ===
Now the reader knows the experiment, give a closer description of possible dangers.

Important, be aware of…Consider the…

=== Other Factors ===
What other things can sometimes affect the result of the experiment. Maybe the humidity or cleanliness of the glass ware is an issue.

=== Show notes ===
What to consider when preparing. How to make it more spectacular. What can be difficult to achieve 'on stage' that normally is easy when practising.
What other experiments are good to that have in relation to this one?
What should you beware of that can make the experiment boring?

== Explanation ==

=== What's taking place ===
Here you can give a more quantitative and mathematical description of what happens. What fundamental laws are involved or demonstrated by this experiment etc. Remember to explain jargon/expressions from the laboratory.

=== In the real world ===
Do you meet things like this in daily life - give examples!

=== Uanswered Questions ===
Things we do not yet know and should find an answer to - maybe how it actually works etc.

=== More Information ===
LEDs change color when cooled by liquid nitrogen.

== 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.
