Rainbow Roses Get white of cream colored long stem roses. (Carnations work well too). Cut the stem according to the picture, you will then place 4 glasses of food color dyed water together. Put one piece of stem per color and allow the flower to soak up different colors.
Milk Art. All you need is milk, food coloring and dish soap. This year in Chemistry I got to test out this project, but my group did it wrong and it didn't come out right.
