This is a great activity to do with your kids to teach them about capillary action.
Start with white flowers of your choice (we used Gerber Daisy's). Place them in water with food coloring and watch it take action! We also split one stem and put it in four colors to get a multi color flower. Pro-tip: the more food coloring the quicker you will get color into your flowers (we learned this as the 3-year old was the one who colored the blue water and it was the first to show color).
Capillary action is when the forces of cohesion, adhesion, and surface tension move liquid up through a solid, like a hollow tube or spongy material. Other ways to illustrate it are with string or paper towels.
