DIY Deoderant

I don’t know about you, but, when you have French class with a lot of other people that have gym with you right before, we tend to be a little smelly, depending on the day’s activity. But, besides the obvious reasons why you wouldn’t want to smell, helping prevent sweat is also good. That’s why I wear deodorant, just like most people in our world. While it is your choice, here’s how to make your own deodorant, and the chemical background of it.

Many deodorants today are filled with chemicals that aren’t safe to use on broken skin. Sweating releases toxins, and we don’t want to be taking in some of the harmful chemicals in our deodorant like, “…aluminum, parabens, triclosan, talc, propylene glycol and phthalates, all of which are harmful when absorbed through the skin.”  Skin absorbs most everything, so, even if there is a warning not to put on broken skin, whatever is in it can still be absorbed. organic products, or ones made yourself, are most ;likely the best way to go, although many companies have started producing organic  or toxic-free deodorant, which is much healthier for you. 

One article states which common chemicals to avoid and why: “

  • Aluminum. Scientists are looking at the link between Alzheimer’s disease and aluminum. It could come in the following forms: aluminum chlorohydrate, aluminum zirconium tetrachlorohydrex gly or other aluminum compounds.
  • Parabens. This group of chemicals is widely used as a preservative in the cosmetic industry. Parabens can mimic the hormone estrogen, which is known to play a role in the development of breasts
  • Triclosan. Thought to contain carcinogenic contaminants which can be stored in body fat.
  • Talc. A known carcinogen, irritant, cause of lung asphyxiation and possible link to uterine cancer. On a softer note, it clogs pores and causes acne.
  • Propylene glycol. A neurotoxin that may cause liver and kidney damage.
  • Phthalates. Shown to damage the liver, kidneys, lungs and reproductive system in animal studies.

To check out some of the FAQ’s of deodorants, check out the link below! Now, onto how to make your own organic deodorant, so that you don’t have to look at teh long lists of ingredients on the back of deodorant in the supermarket.

Ingredients:

  1.  1/4 cup arrowroot powder (as a thickening agent)
  2. 1/4 cup baking soda
  3. 4 tbsp coconut oil (nice moisturizer!)
  4. 10+ drops grapefruit oil
  5. a jar or tin with a lid (to store it in)

Mix all of the ingredients together well. If you want, you can use a hand mixer. It should become a mixture with a balm-y consistency. To keep it solid, store in a relaticely cold place, like a fridge. And that’s it!

Now, she just said to apply the deodorant with your hands, but I think you could take a toothbrush, or a hollowed out chap-stick/deodorant tube and use that. Or you could get a sponge or something. get creative as you enjoy your toxin-free, and deliciously smelling, deodorant!

Cute Cotton Candy Chemistry

RELATING IT BACK TO CHEMISTRY: COTTON CANDY

I absolutely love cotton candy. Not like. LOVE. If you ever want to bribe me to do something, use cotton candy. Due to my obsession with cotton candy, which I only ever get when I’m at a carnival or zoo, when I read my friend Lindsey’s chemistry post on it, i just had to do one, too!

Cotton candy, as seen in her blog post, is made entirely of sugar! The stuff you put in the cotton candy machine is called floss, or, sometimes, fairy floss! Anyway, Lindsey describes sugar in a really simple way: “Sugar is a carbohydrate. Sucrose is a type of sugar. Sucrose is a chemical used in chemistry. The chemical formula is C12H22O11. Sucrose has 12 Carbon atoms, 22 Hydrogen atoms, and 11 Oxygen atoms.”  Artificial flavoring, along with dye, are also used, and that gives it the trademark pink or blue color.

One other post by another blogger stated his dislike about not having the cotton candy fresh on a stick, and explained more about how it’s made.  “When you pour sugar into the center of a cotton candy machine, the coils inside heat the sugar to its melting point and break the bonds of the constituent molecules. The hydrogen and oxygen atoms rearrange to form water molecules and promptly evaporate, leaving only carbon behind. The carbon burns, and the sugar begins to caramelize.”

I, too, am a fresh cotton candy person myself, as it is more fun and tastes better when fresh from the machine. Once the sugar floss is in the machine, and after the caramelization, the machine continues revolutions (about 60 per second) and the now hot sugar is forced in a circular motion through the machine from tiny holes in the side. These sugar strands turn solid as soon as they are exposed to the cool air around it.

Cotton candy is one of the only delights that is both commonly seen at fairs and carnivals and needs a special machine that allows the magic of fluffy goodness to melt in your mouth.

The Periodic Table of Edible

I thought this idea was absolutely awesome! After all, what better way to learn about the periodic table than to bake it? (And then eat it!) But the periodic table is much more than just a bunch of color coded boxes, or, in this case, cupcakes. The periodic table shows some valuable information, just by the location of elements.

But…I figured cupcakes, and the chemical reactions behind them, where a little more interesting to think about, especially after thinking about those delicious cupcakes! Cupcakes, as you probably know, use a good amount of sugar! One site writes, “Sugar contains amino acids that start the caramelizing process and release a chemical called aldehyde.” This is why some pastries have a brown-ish color.

Both baking powder and baking soda produce carbon dioxide, or CO2, as they are heated up. This is what makes it lighter, as it creates air pockets within the pastry. Baking powder is the better choice if you have both on hand, as it requires less chemicals to balance out the flavor. Eggs act as a binding agent, and are seen in most baked goods because of this. You can’t exactly eat a cupcake that isn’t holding itself  together! (You’d have a crumbly mess!) Egg whites are made of mostly protein, which then break down once  heat is applied. In addition, they also add an airiness to whatever fluffy edible masterpiece you are making!

The periodic table is important, and, of course, so are baked goods! I would eat Ta and Ra if I could! Which ones would you eat? Comment below!

Slushie Steal

Remember those commercials for pillow pets? And then the ones for cuddle-uppets and the hanger that collapses to make more room in your closet? And what about those really big pipe cleaners that you could turn into fuzzy monsters? What were those even called? There are so many infomercials, it’s hard to keep them all straight. The only time I have ever bought one of those products, and it wasn’t from the “But wait, there’s more!” line either, it was at a store where it was being sold for 15 dollars less than on TV. So I wasted a grand total of five dollars on something I could have done at home. That’s right. Slushy Magic.

 (See comercial here: http://www.youtube.com/watch?v=oi-3retwNBE)

I know what you’re thinking, but it does actually work. It takes longer than advertised, and there’s a really annoying hole at the top just in case you used soda that spills the liquid everywhere, but it works. I have enjoyed many a slushy with that thing. I had to, I payed for it! But I thought, what is the actual science behind it?

Well, it’s not the “Snowflake science” that’s advertised, nor is it the magic ice cubes that come with it. It’s salt. That’s right! The stuff that you can buy a lifetime supply of in the supermarket, for waaay less than on TV. (But it came with a slushy straw and a drink guide!) Anyway, if you freeze a large quantity of salt mixed with water in a bag, it turns into slush, and doesn’t completely freeze. (You can freeze it overnight, or until it turns a white-ish color.) Then, put that bag inside a larger bag (reccomendation: salt-water in quart size, put into gallon size) but do not unzip or open the bag with the icey slush. Instead, pour in your liquid of choice and seal the. Then shake it, sh-shake it, shake it, sh-shake it, shake it, sh-shake it, shake it like a Polaroid picture! 

Salt lowers the melting point of water. To make a slushy, teh drink needs to be really cold, but not cold enought to freeze. Therefore the slat acts like a catalyst. One site explains, ” To make a slushie you want the temperature around the bag of your favorite drink to be lower than 32 degrees so your drink will freeze. When you add salt to the ice cubes you lower the melting point of the ice cubes by several degrees. The ice cubes stay colder, longer – long enough to turn your drink slushie.”

Happy slushie eating!

Fake Snow???

snow

Okay, so maybe this picture doesn’t have fake snow, but that does’t mean we can’t make it! Fake snow can be made with paper, you know, cutting out triangles and stuff, but I think it’ll be more fun to use chemistry!

This fake snow is made of polymers. It is non-toxic, can feel cool to the touch, and can last for days! You can always buy fake snow, but it will be *cooler* to make it yourself. You can get a polymer called sodium polyacrylate from disposable diapers or as crystals in a garden center. All you have to do is just add water. Literally! Just add water! Then you can mix it so it feels like a gel. You can add as much water as you want to get your desired effect. Don’t worry, the gel won’t dissolve. It just depends on how slushy you like your snow. If you want to make your snow even cooler, literally, put it into the fridge. It won’t dry out, and you can always add more water.

When you are done with your snow, not that you would ever get rid of it, you can throw it out. If you want colored snow, you can mix in some food coloring. For drier snow, you can add some salt to it to help absorb the water.

Warning: Do Not Eat. Non-toxic doesn’t mean edible.

Enjoy!

OMG: Oh My Glowstick!

glow sticks

Who doesn’t love stuff that glows in the dark in uber cool colors? No one, that’s who! So why not talk about something that many of us have seen at parties, handed out at school, or used in the “real world”? Glow sticks are sometimes relied upon for military use, police use, fire use, and EMS operations, along with the recreational uses.

Glow sticks contain fluorescent dyes called sensitizer and and fluouphor. The dyes are mixed with hydrogen peroxide and contained in a plastic tube. These can be combined in a variety of ways with different ratios to produce a brighter, shorter glow, or a dimmer, longer light. One site writes, “Putting the glow stick in a cooler environment slows down the reaction which creates a dimmer glow that will last longer. In contrast, placing the glow stick in a hotter environment will exaggerate the glow but will shorten the lifespan.” The dyes, obviously, show the color, and then the other two are chemicals that, when combined, give off light.  A common combination of chemicals is hydrogen peroxide and phenyl oxalate ester, plus the fluorescent dye. Glow sticks are encased with a glass vial on the inside and on the outside have a plastic tube. To activate them, you bend the plastic so it breaks the glass, creating a reaction contained safely inside the plastic!
