Why Chlorophyll Is Green

Plants are green because chlorophyll absorbs blue and red light. (Stiller Beobachter)

Have you ever wondered why plants are green instead of blue or purple? It’s because they are chock full of chlorophyll. Plants use the pigment chlorophyll to absorb the solar energy they need to perform photosynthesis, converting carbon dioxide and water into sugar (glucose) and oxygen. Chlorophyll appears green to our eyes because most of the light it absorbs is blue and red, leaving behind the rest of the spectrum, which averages out to green.

The reason chlorophyll absorbs blue and red light is because very specific energy wavelengths are used to break the bonds in molecules used to perform photosynthesis. The molecule makes the most efficient use of the energy provided to it by absorbing only the wavelengths it needs.

There are, however, other pigment molecules in plant cells that do absorb green. For example, some carotenoids appear red to our eye because they absorb green. Most of the time, a plant appears green rather than another color because there is so much more chlorophyll compared with the amount of other pigments. You can see some of the other colors when plants stop producing chlorophyll in the fall.

How To Make Peppermint Slime

Peppermint extract and glitter turn ordinary slime into holiday peppermint slime.

Peppermint extract and glitter turn ordinary slime into holiday peppermint slime.

Here’s a simple slime recipe that’s perfect for the winter holidays! This peppermint slime smells like candy canes. You can color it green or red or even combine clear and white batches to get a candy appearance. It won’t taste like candy canes, but it’s not toxic (just in case little ones decide to sample it). It is a borax-free slime. You could also adapt any of my other borax-free slime recipes to make peppermint slime, if you don’t have all the ingredients for this recipe.

Peppermint Slime Ingredients

The recipe uses a bit less than a full bottle of glue, which is great because having leftover glue can help you adjust the consistency of the slime.

  • 1 cup non-toxic glue (clear for translucent slime or white for opaque slime)
  • 1/2 cup liquid starch
  • 1/4 to 1/2 teaspoon peppermint extract (depending how strong you want the scent)
  • food coloring
  • glitter, spangles, or other decorations

Make Peppermint Slime

  1. Mix food coloring into the glue to achieve the color you want. You can add more later, but it’s less messy to mix it in before the slime polymerizes.
  2. Work starch into the slime until you get the consistency you want. You want the slime to stick together, but not be glue-sticky on your hands. Kids can do this part by hand, if you like.
  3. Add the glitter or sparkles.

If the slime is still sticky, add a bit more starch. If the slime is stringy and won’t hold together, add the leftover glue. There’s no right or wrong mixture — it’s all up to you! You can wash the slime from surfaces using warm water. Because of the food coloring, it can stain clothing and carpet. Store the slime in a sealed container or plastic baggie to keep it clean and prevent it from drying out. You can refrigerate sealed slime if you want to keep it for a long time.

Other Types of Holiday Slime

You can easily adapt these instructions to make cinnamon slime or pumpkin spice slime or whatever you like. Just change the color of the food coloring and the extract or spices. If you decide to go with cinnamon, be careful, since the oil is very irritating to eyes and skin. It would be much safer to crush cinnamon candies into slime or add powder. For any extract, use the smallest amount needed. You can always add more, but can’t subtract ingredients once added to the slime. Have fun!

Copper in a ring turns finger green.

Has a ring ever turned your finger green, black, red or some other color? Share your experience. What color did your finger turn? What type of ring were you wearing? Are there some types of rings that work better for you than others? You’re welcome to share your experiences…

Mood Ring

It’s probably nickel, but I’m not sure. It is a cheap mood ring. The surprising thing is that I only wore it for a few hours.

Ring Turned My Finger Black

I was on Marco Island, sitting in the water at the beach all day, while digging for shells with my hands. The spot was at the edge of the water, so when I would dig down, my hands were under water. Well, I was wearing my wedding band and wedding diamond that day. They are both 14 carat yellow gold. I have had these rings for 9 yrs. at the time and NEVER had any type of discoloration at all. When I came in to take a shower is when I noticed that my finger turned a blackish – grey color. Pretty weird since I’ve worn the rings many times in that same water and never had a discoloration. Maybe it was a reaction from the shells since I basically had small shells in my hands for hours, just scooping away as I sat at the water’s edge in my beach chair, talking up a storm with my mother in law.

Copper Ring Turns Finger Green

As far as I know, the only metal that turns my finger green is copper. It’s not toxic. Actually, I think it’s supposed to be therapeutic for some conditions. However, it is not attractive. It has to wear off rather than wash off.

Grow Blue-Green Copper Acetate Crystals

Copper Acetate Crystals

Copper Acetate Crystals (Choba Poncho, public domain)

It’s easy to grow large naturally blue-green monoclinic crystals of copper acetate monohydrate [Cu(CH3COO)2·H2O].

Materials

  • copper acetate monohydrate
  • hot water
  • acetic acid or vinegar (if necessary)

Procedure

  1. Dissolve 20 grams of copper acetate monohydrate in 200 ml of hot water. If you don’t have a scale, don’t despair. Dissolve the copper acetate in warm water to create a saturated solution. You’ll know you have enough of the powder added when it stops dissolving in the liquid.
  2. If you see a scum of undissolved material, stir in a couple of drops of acetic acid (vinegar).
  3. Place the container in an undisturbed location to allow crystal to grow.
  4. Blue-green crystals should start to appear within a couple of days. You can allow them to grow on their own or can you can select one perfect crystal to use as a seed crystal to grow larger crystals.
  5. If you wish to grow a large single crystal, place the seed crystal in a new container and add the copper acetate solution from the old container.
  6. When you are pleased with the crystal, remove it and place it on a paper towel to dry.

You can also grow copper acetate crystals using a penny:

Two Ways To Make Green Fire

greenfireGreen fire is one of the most vibrant forms of colored flames. It’s also one of the easiest to produce with common materials!

Borax or Boric Acid Green Fire

Borax and boric acid are two boron salts. Borax is sold as a laundry detergent booster or household cleaner. Boric acid is sold as a roach killer or as a disinfectant. Adding either chemical to a fire yields a vivid green flame. For best results, mix borax or boric acid with methanol, a type of alcohol, and ignite the solution. The alcohol will burn off, leaving behind a white residue from the boron compound. You can add more alcohol to produce more colored fire. The boron compound is not consumed, so it can be re-used.

Copper Sulfate Green Fire

Copper sulfate is used as an algicide and root killing agent. You can sprinkle copper sulfate on a fire to impart a green flame. It mixes well with rubbing alcohol to produce pure green fire. The copper compound won’t be consumed by the fire, so simply add more fuel to maintain the color. This compound also works on a wood or charcoal fire, although you can expect a rainbow of colors from the interaction with other chemicals in the fuel.
