With the whole idea of photography I decided to do an experiment that consist of roses, water, and food dye. I am sure this is a very popular project that is often done in any science class but I thought it would be interesting to discover why the rose reacts to the water and how does this happen. As you can see below I had 4 roses and put them in separate flasks with different liquids. The tallest rose has green food dye and water, the second has raspberry liquor with water, the third rose has orange food dye with water, and finally the last one has vanilla extract with water. I let that sit over the weekend and when I came there was food dye on the flowers, but I was hoping the smell or even taste from the vanilla and raspberry would transfer onto the roses like the dye but it didn't. The Vanilla extract flower did for a day and then it just started to rot the tips of the flower and the raspberry smell did not go through at all.
How does that happen!?
What happens in this experiment is called "Capillary Action," basically what that is, is the suction that happens in the stem of a flower (in my case the roses) that brings the food dye into the petals and changes the color of the rose. An explanation as to why some of the colors and smells did go through while the other ones didn't is, cohesive force and adhesive force. They are to blame because cohesive force is the intermolecular bonding of a substance where similar attractiveness makes them keep a certain shape of the liquid. Adhesive force is when forces of attraction between unlike molecules happen. So the answer to why some worked and others didn't is because capillary action will only happen when adhesive forces are stronger than cohesive, some levels in the mixture might have not applied to the capillary rule and thats why it failed.
