Now Fold The Coffe Filters In Half, Then Half Again To Make A Wedge Shape.
In a chromatography experiment, the brown will separate into different colors; Use the triangle to make a sail. Pour two tablespoons of water into the cup.
However, The Red Will Not.
Our kids party craft packages create endless fun for slumber parties birthday parties and more. Fold the coffee filter in half twice, and put it in the cup. Leave to dry for about 15 minutes.
Repeat With Different Colors On Different Coffee Filters.
Start with a piece of filter paper. Use your water based markers to make a dramatic circle in the middle of the coffee filter. Use larger jars for the colors that have more markers.

It is quick and easy to do, requires minimal materials and clean up, yet it keeps the kids completely engaged and occupied. Chromatography is the separation of a mixture (e.g., marker ink) by passing it in a solution (e.g., water) through a medium (e.g., coffee filter) in which the components of the mixture (e.g., the various colors that make up any given marker color) move at different rates. Do this with each color marker you’d like to try out.
Watch It Diffuse And Change Colors.
Upcycle an old serving tray into something bright and new! For example, only one dye is used to make our red color marker, but a number of dyes are used to make our brown color marker. (you can also use a pencil to lightly write the name of the color marker you used on the strip so, when you’re finished, you’ll know which strip started out as each color.)
