Spinach Glows RED

Materials:
Spinach leaves
Blender
Beaker
Rubbing alcohol
Gauze
Black light


First me, sam, and josh grabbed a handful of spinach leaves and put them into a blender. After we poured enough of rubbing alcohol into the blender so that the alcohol covered the leaves. Completely blending the materials together, they turned out to turn the clear liquid into a green color. Next we took the gauze and covered the beaker so that no liquid could go through with out entering through the gauze first. Taking the blender with the contents inside slowly poured the liquid and spinach into the beaker. Once all the liquid was poured all the gauze filtered the solids outs. Now that the chunkier parts are out we placed it under the black light. Why did it glow red? The liquid was green in regular light.
When the florescent light is directed toward the chlorophyll and thats when the chlorophyll electron become excited. Because the chloroplast thylakoid membranes were dissolved  there is no cytochrome transport system. The chlorophyll absorbed the light and give up their energy state which releases its reddish glow.
