Add a little color to your life when you play around with these 6 science experiments using food coloring

Food coloring is a good tool for adding color to your baked goods, but you can also do it to make science experiments just a little more fun. The coloring makes it much easier for people to see scientific processes that may otherwise be invisible to the human eye.
Food coloring can stain hands and clothing, so wear gloves and clothes you don't mind getting messy before you tackle these projects.

1 Sugarwater density experiment
When you're out on the water in a boat, you're likely not thinking about water density. But that scientific concept is precisely why your boat floats (or doesn't). When an object is denser (heavier) than water, it sinks. In this experiment, you'll see how different amounts of sugar affect the weight of water.
2. Flowers and food coloring (h/t Powerful Mothering)
This classic science experiment is an excellent way for curious minds to see just how plants absorb their nutrients. The plants absorb the colored water and transport it to the petals through tiny tubes in the stem. This happens when water from the leaves and petals evaporate. The evaporation pulls other water molecules to the surface of the petals.
3. Colored ants
Ants are pesky little bugs that seem to get everywhere you don't want them to be. But, you can make these critters a little more entertaining by feeding them colored sugar. Once they ingest the sugar, their abdomens begin showing whatever color they noshed on. This works because an ants abdomen is somewhat transparent so you can see the colored food inside their bodies.
4. Color changing milk
This fun project works because milk contains fat proteins which do not dissolve in water. When you add soap to the mix, however, the fat moves around as the solvent tries to connect with the fat molecules. This mating ritual of sorts gives you an idea of why soap is an effective dish cleaner!
5. Make your own eggshell geodes (h/t Science Bob)
This process works because the water solution becomes "supersaturated." The term just means that the salt dissolves until there is no room between the molecules. As the water cools, energy dissipates, and the rock crystals solidify. As evaporation slows the growing process, the crystals become larger than they were before.
6. Color mixing ice (h/t Learn Play Imagine)
Help kids learn what happens when colors mix by using colored ice cubes. As the water melts, the colors blend creating new colors. Try different combinations as well as some clear ice cubs to see how that affects the original colors.
