Editing Fluorescent Liquids (section)

== Demonstration ==

# Lay out the black cloth on the table, and set the fluorescent liquids box underneath to use as a backdrop. Set out the eight bottles in the color order provided in the Why This Works section. Place the black light either between the bottles and the box or on top of the box. Turn on the black light. Set the Q&A cards in front of their respective bottles. If you'd like, you can also set out the wooden frame with the five smaller bottles, but keep it aside and don't allow students to handle it.
# As students come up, ask them to try and identify the liquids inside of each bottle, and after each guess they can look at the Q&A card for the respective bottle. Some of the liquids they won't recognize, but most of them they will!
# After students make guesses, you can turn off the black light to show what colors the solutions are normally. What causes them to change color? Why do they glow?
