First, O poured water into 4 test tubes (I bought these on clearance after Halloween...they were filled with gummy body parts in candy jelly, which we threw away).
Then, she squeezed LOTS of food coloring in to each test tube. The tubes were red, yellow, green, and blue (the food coloring was so dark that you couldn't really tell which color each tube held at first).
Our last step was putting one beautiful white Camelia into each test tube.
Within about 3 hours, the petals were already starting to turn colors. This was SO exciting because this is the FIRST year this experiment has worked (and it's our 3rd year doing it!). I realized last year (too late) that it wasn't working because we weren't using enough food coloring.
All of the petals fell off the blue and green flowers after only one day. Luckily, the girls didn't mind. I'm so glad this project finally worked!
