๐Ÿ’›๐Ÿ’™โค๏ธPrimary Colors, ๐Ÿ’ฆWater & Paper Capillary Action โŒ›๏ธTimelapse โš—๏ธ Kids Science Experiment (๐ŸŒˆ Rainbow Walking Water)

Today, we are conducting kids science experiment: Capillary Action (also called Rainbow Walking Water), which is a timelapse experiment on water and paper's ability to transfer color from one glass to the other, mixing two primary colors and, in the process, creating secondary colors. This is also a fun sensorial activity for your child to learn primary and secondary colors while developing fine-motor skills via a use of a dropper. 

DSC_0045What you will need:

  • five clear glasses filled with water;
  • three primary coloring (yellow, blue and red);
  • dropper;
  • paper napkins (a๐Ÿ’กTIP: the thicker the paper, like a kitchen paper-towel, the longer it will take to transfer water and color from one glass to the other; on the other hand, if the paper is too thin, like toilet or tissue paper, it will simply dissolve prematurely, so paper napkins worked best for us for this experiment);
  • a tray ( we are using a wooden tray, which I lined with a shelf-liner).

DSC_0045The three primary colors are what ALL other colors are made of.

You will add to glasses one, three, and five –  yellow, blue and red coloring respectively, leaving the two glasses in between with uncolored clear water. You will then fold paper napkins and insert into the glasses to connect all the glasses with each other. Wait and observe …

Science mystery๐Ÿ’ก revealed: capillary action is a process during which liquid, like water, moves up into a material with a lot of small holes (like paper). If the water is colored, the paper will show the passage of water more obviously. Capillary action happens when three forces called cohesion, adhesion, and surface tension work together.

DSC_0067A few hours later.

Capillary action occurs because water molecules bond together due to forces of cohesion and adhesion, as well as stick to other substances such as paper. Adhesion of water to the surface of the material (paper napkins) will cause an upward force on the liquid (colored water). The surface tension acts to hold the surface intact. Capillary action occurs when the adhesion to the surface material is stronger than the cohesive forces between the water molecules.
DSC_0067In the process of our capillary action experiment, primary colors mixed together with a help of a "waking water" and paper napkins, making two secondary colors – green and purple:

  • ๐Ÿ’› yellow +๐Ÿ’™ blue =๐Ÿ’š green;
  • ๐Ÿ’™ blue +โค๏ธ red =๐Ÿ’œ purple.

DSC_0067Sunlight shining through the glasses made the colors even more inviting.
