Dying Yarn (or Your Hair) using Kool-Aid
- by KitchenPantryScientist
You can dye a rainbow of streaks in your hair using Kool-Aid drink mix. Practice on yarn first to perfect your technique!
Sheep’s wool and human hair are both made up of proteins called keratins, which can be dyed using chemical mixtures called acid dyes. These dyes are used to dye wool and alpaca, and some of the non-toxic ones can be used to dye human hair. Despite their name, they don’t actually contain acids. Instead, they require mild acid, such as citric acid or vinegar to be present in order for them to attach to proteins.
Kool-Aid drink mixes contain acid dyes that are perfect for dying keratin, and the color will wash away in a few washes. The mixes usually contain citric acid, but it helps to add vinegar as well to create an acidic solution. Colors will be most visible on lighter-toned hair or hair that has been chemically lightened, but you can dye dark hair too, by using more Kool-Aid mix.
Remember, Kool-Aid stains skin, fabric and other surfaces!
To dye yarn you’ll need:
100% wool yarn (white or cream, not cotton or synthetic fiber)
Kool-Aid drink mixes (powdered or liquid concentrate)
- Cut yarn into desired length and tie into bundles.
2. Soak yarn in warm water for 30 minutes.
3. In small containers, add enough vinegar to cover yarn and enough Kool-Aid to create intense colors.
4. After 30 minutes, put the wet yarn in the vinegar.
5. Soak for 30 minutes to overnight.
6. Remove yarn from dye, rinse well with cold water and hang to dry.
7. To make multi-colored yarn, soak yarn in vinegar and then squirt dye directly onto yarn. Let sit, rinse out and dry.
To dye streaks or the tips of your hair, shampoo and dry your hair. Skip the conditioner and put on an old shirt that can be stained.
Add the desired shade of Kool-Aid to vinegar in a bowl and soak the portions of your hair that you want dyed in the Kool-Aid mix for half an hour or so.
Rinse ends several times and dry. Remember that if your hair gets wet, it may transfer color to your clothes!
Edible Alien Eyeballs- A Diffusion Experiment for Halloween
- by KitchenPantryScientist
Molecules move from areas of high concentration, where there are lots of other similar molecules, to areas of low concentration, where there are fewer similar molecules in a process called DIFFUSION. When the molecules are evenly spread throughout the space, they have achieved EQUILIBRIUM.
Lots of things can affect how fast molecules diffuse, including temperature. When molecules are heated up, they vibrate faster and move around faster, which helps them reach equilibrium more quickly than they would if it were cold. Diffusion takes place in gases like air, liquids like water, and even solids.
You can watch food coloring molecules diffuse into gelatin (a colloid) when you do this fun, edible Halloween experiment.
Dissolve two 3oz packages of lemon Jell-O in 1 and 1/4 cups of boiling water. (Adult supervision required.) Allow it to cool briefly, and pour it into 2 ice-cube trays with oval-shaped holes. Refrigerate until firm.
Dissolve one 6oz package of Berry Blue Jell-O in 1 and 1/4 cups of boiling water. Cool briefly.
Using the end of a potato peeler or a strawberry corer to hollow out a circle in the middle of each yellow Jell-O “eyeball.” Carve the circle about halfway to the bottom of the gelatin. Use a toothpick or skewer to remove the Jell-O.
Fill the hollow with melted blue gelatin and return to the refrigerator to harden. The blue Jell-O will be the pupil of the eye.
Set ice cube trays containing Jell-O in a casserole dish of hot tap water for 1-2 minutes. Turn upside down in another dish to un-mold and then move your eyeballs to another serving dish.
Use a straw to add Kool-Aid liquid (like Cherry) to the center of each eyeball. Then, use a sharp skewer to draw lines out from the center.
Cover with plastic wrap and let sit for a few hours so the Kool-Aid will start to diffuse.
Add a second color Kool-Aid drops (Like Blue Raspberry) to the center of the eye and repeat.
Cover and refrigerate until ready to serve. The Kool-Aid colors will continue to diffuse into the eyeballs!
