“What if” questions often lead us to wild science adventures. So recently, when we successfully extracted chlorophyll from maple leaves (read about it here), the natural “what if” question that floated to our minds was, what if we take the extracted chlorophyll and put it back into the plant?
Anyone who had ever sat on the grass in white cotton shorts knows how well the green color transfers to clothing. But it would be hard to observe if green leaves turned greener. However, if we were to take white flowers and stick them in a cup full of freshly extracted chlorophyll, we could easily get observable reaction. Right? We had to check!
Plant Science: Chlorophyll as a coloring agent
What you need
What to do
To extract the color from the spinach, I put a bag of washed spinach in a food processor. (I washed it because at this point, I was still thinking; mmm maybe there will be some left for me to eat), but if you are not planning to eat this spinach, you can skip washing.
I blended spinach until it was completely processed into a foamy green … (Is it just me or it bears a stunning resemblance to pond slime?) At this point, I decided that I will dedicate all of my spinach to science.
So, now we had chlorophyll extracted from spinach (Sample 1) and chlorophyll extracted from maple leaves with alcohol (Sample 2).
To make it even more exciting, we decided to add two more samples. A cup with green food coloring (Sample 3) and one more glass tinted with green sprinkles (Sample 4).
