First off, the necessary safety warnings. This shit is NOT even remotely edible, and in all honesty, I would wear latex gloves. But it’s fun. A whooooooole lotta fun. Just….wash your hands after. You’ll see why.

Very basic experiment, anyways…you shouldn’t fuck up.

Materials Needed:
◊ Polyvinyl alcohol solution (preferably 4%ish…can usually be found as a sponge-mop head refill, rubbermaid, like $9 maybe?…..do NOT confuse with polyvinyl acetate. Just….don’t. If you decide to try, have poison control on the line when you do so, k?)
◊ Food coloring!
◊ 4% sodium borate solution (this is borax…..thats it, borax; dissolve 4 grams of it in about 100 mL of water, or, to make it easier, do about 38 grams in 950 mL, or roughly a 10th of a pound of borax in 8 cups of water. Stir til clear.
◊ A glass or plastic container you wont mind throwing away when you’re done with it.
◊ Some sort of heavy-duty stirring object, preferably metal or wood, also willing to be thrown away or vigorously cleaned.

Process:
1.) Don gloves.
2.) Place a little over 4 fluid ounces of the PVA in the plastic/glass container. (If more is desired, use a cup of PVA instead).
3.) Stir, damn you, stir like your life depended on it! (and add a few drops of food coloring while you’re at it!)
4.) Add (if 4 fluid ounces of PVA used, add 1/3 of a fluid ounce of borax soln (solution in chemistry-speak); if a full cup is used, add about a 10th of a cup.*** (Yes, these are tiny measurements, but in the world of chemistry, small can make a biiiiiiiiiiiig difference). *Insert joke about “It’s not how deep you fish but how you wriggle the worm” here*
5.) Stir. Stir some more. Sing a sea chanty while you stir. I don’t really care so long as it gets done. As a result, you should get a quickly-thickening, slimy soln. The more you stir the more dense and slimy and thicker it will get — lets it sit and it will harden. If you wanna play with it, take it out and put it in a baggy and use it in that, unless you happen to have covered your counters with newspaper, in which case, bounce that shit around!
6.) ….wash your hands. You have a chemical slime on it :p Common sense, please.

(And why yes, this IS the same slime from ghostbusters and nickleodeon’s famous green slime.)

*** Do not attempt to create a “recipe” because these are conversions of metric measurements….a ratio of 2/25 (mL) of borate/PVA is used.
The science behind it!
Geek Warning:
Science follows this warning. Keep all disinterested, ADD or liberal-arts majorsrs out.

The polyvinyl-sodium borate solution acts as what’s called cross-linked condensation polymer in chemistry and a non-newtonian fluid in physics (and THOSE are fun….believe you me). Basically, the result of this means that the polymer will have tensile, elastic and much more fun properties. When mixed, the borate ion that was separated in the solution (into sodium (Na+) and borate (B4O5 2-)) will cross-link with the multiple hydroxyl groups on the PVA’s molecular spine, which makes a 3D structure. And since both are aqueous solutions, the the remaining holes in the network are filled with water, resulting in a gel! Thus, you have a slimy gel made of roughly 90% water! (The chemical formula of one of these units is 2(CHOHCH2CHOHOHCH2CHOHOH)B ….or in other words, a double 5-carbon spine (CHOHCH2CHOHOHCH2CHOHOH) back to back with multiple hydroxyl groups bonding to a single boron. Since this is quite weak (this complex coordination compound has, as the name implies, double the bonds of it’s charge), the boron-hydroxyl bonds are interchangeable and means that it is very easily malleable and play-with-able and god-knows-what-other-fun-reasons-you-can-come-up-with. This is called dynamic equilibrium (and is not the same dynamic equilibrium as in microtubule GTP/GDP/actin complex in cellular mitosis, so cell biologists get it out of your heads :p). Basically, since the borate ions and hydroxyl groups stay in close proximity, you can reshape this as much as you want before it dries out! Have fun sliming!

…..since I’m a chem major, I figured I;d do something related to my schoolwork and turn this into a “fun experiments you can do at home” thing. Believe me — I will not give you dull experiments. Just…..

A woman decides to go to Germany to hear a very famous man give a speech.  However, she doesn’t speak German, so she hires a translator.  They arrive on the day of the speech, and the man begins speaking.  The translator says nothing.  The speaker continues and still the translator says nothing.  The woman gets mad and says “What are you waiting for; start translating!  I’m not paying you to sit here!”  The translator looks at her and says “I’m sorry ma’am, I’m waiting for the verb.”

When the letter from the psychiatrist arrived I read it and then threw it in the garbage. I act dumber than I really am around my friends and I never told them that I took the IQ test. It’s rather funny because my friend’s girlfriend thinks she’s the most intelligent out of our group and is very arrogant at the same time. I laugh at her a lot.

Results from my blood test are in.  If you don’t remember my whole deal with this, I was being tested for hypo- and hyperthyroidism.  Hypothyroidism basically makes you fat, lazy, and depressed.  Hyperthyroidism makes you energetic and hyper and cheerful.  I’ve known for years I would get one or the other.  It’s pretty much inevitable, knowing my family history with it.  But for the last few weeks since the doctor’s appt., I’ve been pretty sure that I would have hypo.  Why?  Because I am fat, lazy, and depressed.  So for the last few weeks, when my self-esteem went down, I could say to myself “Well, it’s probably just because of this thyroid thing.  Once I get on medication, I’ll be better.”  Buuuuuuut, it turns out I have fucking asymptomatic hyperthyroidism.  So, I get all the shit of having to be on meds my whole life, without any of the energy or cheerfulness.  And I really am just fat, lazy, and depressed.

I really hate the phrase “fml”, but holy shit, I am using it now.  Fuck.  My.  Life.

Story of my life, quite honestly. Attempting to do French homework right now.

Should be doing AP Bio.  Not doing AP Bio.  I can get away with pushing it to Monday.

To Barnaby: You’re a such prick and I can’t believe I tried impressing you for the first half of the year! WTF. Now that I’ve discovered that you will never be into me that’s totally cool because I’m continuing to surround myself with people I love and who love me back. Also,you’re voice. It’s annoying. Like,every time you speak,in my head it’s like ‘AHH JUST SHUT UP. NO ONE CARES THAT YOU WENT TO FRANCE,YOU’RE NOT AS COOL AS YOU THINK YOU ARE.’ You also wore plaid yesterday and today so that kind of bugged me, and it was the same color so yeah it was kind of annoying. You need to have like,at least 3 days in between that wearing plaid mmkay? GAH. I’m sorry I’m being so mean,and you really haven’t done anything to me but I think I’m more mad at the fact I even wanted you to like me.

To Saemore: DUDE CHILL OUT. You need to step back and laugh at something so immature, so unrealistic and not get uptight by the fact that it’s not right. And stfu because you’re not right about everything and you will never change my opinion about certain things. Stop thinking you’re better than everyone else just because you act like a 50 year old man. Oh and never ever tell me I’m wrong about my religion and keep posting shit about how there’s no god and how you’re so fucking righteous. I’ll give it right back to you,boy. And you’re not unique because you believe that okay? Stop acting like it. Seriously dude you’re annoying. I know you’re insecure and shit but sometimes you just need to SHUT UP. In addition, stop being such a prat to my friends. Thanks to you being a jerk to them,and criticizing them, they think you’re a dick. COOL. WAY TO GO. I’m not going to stop loving them just because you think me and Ashton should be you’re only friends. GAH YOU’RE SO ANNOYING SOMETIMES.

PS- My friends are fucking rad. There’s obviously a reason why I love them so much.

Lol.  I thiiiink I might know who Barnaby actually is.  Colin?  Saemore, no idea.  But he sounds like a douche.

Also, you’re friends with Hannah McMurray, right?  What’s wrong with her?  She was crying today during AP Bio. D: I felt so bad for her.  She usually seems so peppy and cheerful.

And I know you know Staci Cccccc (not even going to attempt her last name.  Tricky spelling).  I used to think she was sort of mean, but we were talking today during gym, and she seems pretty nice, actually.  Do I just fail at judgment?
