Science Theatre demonstrators must keep the safety of themselves and their audience in mind at all times. All Science Theatre demonstrators must have read through the Safety Training page. The ST Safety Box with first aid kit, fire extinguisher, etc. should always be available to demonstrators. Always wear safety gloves, glasses, and a labcoat if handling chemicals; always perform potentially dangerous demonstrations at a safe distance from the audience; and always keep a very close eye on any volunteers you call from the audience. The chemicals used in this demonstration are safe to go down the drain, as long as you dilute them with water.
Please read the Dry Chemical and Liquid Chemical sections of the [[Demonstration Safety]] page before performing this demonstration.

This is where you would provide a basic, easy-to-understand explanation of the demonstration. Try not to use too much "Science Jargon", and if needed add any explanation tips, like comparing the demo to something kids are familiar with.

===Full Explanation===
This is where you will explain the demonstration in full, and provide all additional information that pertains to the demo. Unlike the short explanation above, this should be worded so someone who is familiar with the topics might understand it. If needed, you can provide equations and citations for additional sources of information on the topic. This is also where you will find some answers for trickier questions, such as "How does a plane fly upside-down?" for the Bernoulli's Principle demo. If you want to add a floating box for equations, copy the following:


You will need to shake vigorously or use a stir plate and stir bar to get everything to dissolve. Make sure everything dissolves!

Lightning is also a chemiluminescent effect. It is an electrical discharge in the atmosphere that excites electrons in the gas molecules in air, which then fall back down and produce photons. Lightning also dissassociates diatomic nitrogen and oxygen, which can then release photons when they recombine.

Preparation

Solution A: Mix the following chemicals into 500 mL of DI water in order, stirring constantly. Do not add the next chemical until the one prior is fully dissolved. Mix these chemicals either within a dark bottle or in a room with the lights dimmed, as some of them are light sensitive.

  • 4.0g Sodium Carbonate
  • 0.2g Luminol (3-aminophthalhydrazide)
  • 24g Sodium Bicarbonate
  • 0.5g Ammonium Carbonate Monohydrate
  • 0.4g Copper (II) Sulfate OR 0.25g Copper (II) Chloride

Once all of the chemicals are in solution, add 500mL of DI water to dilute fully. Store in an airtight brown bottle or similar, and label with the Demonstration name, Solution A, and date, as well as your initials.

Solution B: Dilute 5mL of the 30% Hydrogen Peroxide with 1L of DI water. Store in an airtight brown bottle or similar, and label with the Demonstration name, Solution B, and date, as well as your initials.

Presentation
  1. Set up the Spartan "S" board, and connect the single ended tube to the tube cork. Put the tube cork on the vacuum flask, and connect it to the vacuum pump.
  2. Show the audience the two solutions, and ask them if they have seen fireflies before. Can anyone guess how a firefly lights up? Explain that there is a chemical reaction, much like the one that will happen between the two solutions you have.
  3. Put the double ended tube into the two solutions. Explain that the two chemicals will react when they mix and produce light. Ask for a countdown, and at the end flip the switch on the vacuum pump.
  4. Watch as the solutions are pulled through the tubing and start to glow! The vacuum pump will pull the solutions pretty quickly, so make sure to watch the bottles for when they run out.
  5. After explaining the demonstration, put both of the ends on the double ended tube into the water bottle. Vacuum the water through the tubing to clean it, and then let the vacuum run for a minute to pull air through and dry the tubing. The end solution can be poured safely down a drain.
