Editing Shaking Solution (section)

== Demonstration ==

'''Preparation:'''
# In the Erlenmeyer flask, combine 300 mL of water with 8g of Sodium Hydroxide and 10g of Dextrose. Add the solids individually, and allow the first to dissolve fully before adding the next one.
#* Alternatively, if there are prepared solutions for the NaOH and sugar, mix them in the Erlenmeyer flask as according to their labels.
# If your indicator is not already in a water solution, then combine 0.5-1.0 g of the indicator with 50mL of water. Stir thoroughly, store in a bottle and label it. Add 8-10 drops of the indicator solution to the Erlenmeyer flask, and then stopper the flask. 
# The solution will initially be blue (Methylene blue) or purple/pink (Resazurin). After you let it sit, the solution will turn clear (Methylene) or light teal (Resazurin), and it is now ready to use.

'''Presentation:'''
# Show the solution to the students, and swirl the bottle gently. A very slight color change will happen. Let it sit, and after a few seconds the color will disappear!
# Ask a student to hold it and shake it. The solution will now turn colors dramatically! the more they shake it, the more pronounced the color will become, and the longer it will take for the color to dissipate.
# Ask the students why it changes colors. What is happening when we shake it? Is there more than one thing going on here?
