== Demonstration == ;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: # 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. # 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. # 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. # 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. # 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.
