Chromatography Flowers

OLYMPUS DIGITAL CAMERA

Find out what colors of ink are used in your markers! Chromatography is used to break a solution into its component parts. In other words, the colors of markers are often made by combining several other colors together. To split these colors back apart, we need to use chromatography! In this post, we’ll show you how this amazing technique can be used to decorate our Color Diffusing Flowers with crazy effects!

Age: 5+

Duration: 10 minutes (+15 minute drying time)

Learning Objectives: Learn about the properties of colors through chromatography. Learn what chromatography is and how certain effects are produced using simple materials. Develop a basic understanding of the science behind color mixing. Explore fundamental scientific concepts, such as physical (compared to chemical) changes in mixtures.

You’ll Need:

R2440 Color Diffusing Paper Flowers

• Epsom Salts

• Plastic cup

• Warm water

• Markers (washable brands)

Optional:

• Ribbon

• Scissors

Chromatography is a great method to introduce young kids to science… or even to try out for yourself! Basically, the materials used in chromatography help to split a mixture back into its original parts. The Epsom Salts in water attach onto certain molecules in the ink and push them apart. Therefore, it’s a great means of exploring color mixing and how colors are put together to make new ones.

We made a very similar experiment in one of our YouTube videos. Check it out at the link!

OLYMPUS DIGITAL CAMERALet’s start with our materials! As you can see, we’ll need to select a type of flower, some markers and get our basic chromatography equipment ready. Because markers are made with various shades, you won’t have to worry about staying away from primary colors.

Note: I’ve included yellow just to add a colorful range to our chromatography flower, but as I’ve found, yellow is the only color that won’t separate as well as the others.

OLYMPUS DIGITAL CAMERAThere are several different types of flowers to choose from. Select your favorite flower type, then count how many petals are on each flower. Choose a similar number of marker colors per petals on each flower, or double up on some colors. Start at the center of the flower and draw a triangle pointing inwards, with the base facing the petal side. Color in the triangle.

OLYMPUS DIGITAL CAMERAMix one teaspoon of Epsom salts in one cup of warm water. This solution is what you will use to start the chromatography process! I used a wide, flatter cup to help with dipping the flower evenly into the solution.

Pinch your flower at its center until you form a small handle underneath. This will scrunch the flower a little bit, but it’s important to make this “handle” prominent enough that it will reach the surface of the Epsom salt solution.

OLYMPUS DIGITAL CAMERANow dip the handle part at the center of the flower into the Epsom salt solution. See how the petals stick out from the center? The petals will hold the flower in place so it doesn’t collapse into the cup. You can even curl the petals outwards so that they hold the weight of the flower out from the center.

OLYMPUS DIGITAL CAMERAHere, I’ve tried another type of flower. You can see the gradual changes that take place in a matter of minutes!

OLYMPUS DIGITAL CAMERAThe solution is creeping up!

OLYMPUS DIGITAL CAMERAYou can start to see a change in coloration here.

OLYMPUS DIGITAL CAMERANow, the ink has completely covered the surface of the flower and is separating the ink into individual lines of color. See the small patch of purple near the center of the flower? You can see some light pink being separated from the darker purple parts.

OLYMPUS DIGITAL CAMERATa-da! When the Color Diffusing Flower is fully saturated in water, remove from the cup and set on top of a dry container. Leave to dry for about 15 minutes.

OLYMPUS DIGITAL CAMERAI’ve set out all the dry flowers here for viewing. Look at the separation in colors! You’ll see the most differences coming from colors such as teal, indigo, magenta and orange.

OLYMPUS DIGITAL CAMERAHere’s a closeup of some separate colors that went into creating this soft blue color!

OLYMPUS DIGITAL CAMERACheck out this indigo color! You can see tinges of light blue at the bottom, dark blue in the middle and magenta at the top!

A good exercise for kids is to guess which colors might have gone into making certain colors before they use their designs with chromatography.

OLYMPUS DIGITAL CAMERATo make your designs extra special, combine them into a pretty garland!

OLYMPUS DIGITAL CAMERAFold your flower in half, then cut two small slits near the center, at about 2″ apart.

OLYMPUS DIGITAL CAMERAUnfold your flower. Next, weave one end of a length of ribbon through the first slot and back out through the second slot.

OLYMPUS DIGITAL CAMERARepeat for the remaining flower shapes!

OLYMPUS DIGITAL CAMERA…And hang them up! Combining science with art is lots of fun!
