From: mini-AIR June 97 <marca#NoSpam.wilson.harvard.edu> 1997-06-11
Science and love are inseparable. That is the theme of the AIR Campaign for Textbook Improvement ("AIRCTI -- pronounced "AIR kitty"). AIRCTI aims to warm the cold, emotionless textbooks of today by adding to each a love interest.
Investigator Charles N. Horton has synthesized a love interest for the textbook "Organic Chemistry," 4th Edition, by John McMurry (Brooks/Cole Publishing Company, Boston, 1996). Horton mixed in the romance of a couple named Dan and Melissa. Here are relevant, abstracted snippets from the revised textbook:
.. CHAPTER 5: AN OVERVIEW OF ORGANIC REACTIONS Dan was shopping for some organic bean sprouts when he bumped into Melissa. "Oh! You like organic stuff too?" he asked. "Yes," she said, "and I know this great organic cafe..." .. CHAPTER 11: REACTIONS OF ALKYL HALIDES: NUCLEOPHILIC SUBSTITUTIONS AND ELIMINATIONS "Oh no," thought Dan. She already has a boyfriend. I must substitute myself for him! But how? And then a light came on in his mind. "I can eliminate him using an alkyl halide nucleophile!" .. CHAPTER 30: THE ORGANIC CHEMISTRY OF METABOLIC PATHWAYS And so, they lived happily ever after on the pathway of love...

The following recipie for chocolate chip cookies recently appeared in Chemical & Engineering News (C&EN, Jun 19, 1995, p. 100). It was attributed to Jeannene Ackerman of Witco Corp.
Ingredients: 1. 532.35 cm3 gluten 2. 4.9 cm3 NaHCO3 3. 4.9 cm3 refined halite 4. 236.6 cm3 partially hydrogenated tallow triglyceride 5. 177.45 cm3 crystalline C12H22O11 6. 177.45 cm3 unrefined C12H22O11 7. 4.9 cm3 methyl ether of protocatechuic aldehyde 8. Two calcium carbonate-encapsulated avian albumen-coated protein 9. 473.2 cm3 theobroma cacao 10. 236.6 cm3 de-encapsulated legume meats (sieve size #10)
To a 2-L jacketed round reactor vessel (reactor #1) with an overall heat-transfer coefficient of about 100 Btu/F-ft2-hr add one, two, and three with constant agitation.
In a second 2-L reactor vessel with a radial flow impeller operating at 100 rpm add four, five, six, and seven until the mixture is homogeneous.
To reactor #2 add eight followed by three equal portions of the homogeneous mixture in reactor #1. Additionally, add nine and ten slowly with constant agitation. Care must be taken at this point in the reaction to control any temperature rise that may be the result of an exothermic reaction.
Using a screw extrude attached to a #4 nodulizer place the mixture piece-meal on a 316SS sheet (300 x 600 mm). Heat in a 460K oven for a period of time that is in agreement with Frank & Johnston's first order rate expression (see JACOS, 21, 55), or until golden brown.
Once the reaction is complete, place the sheet on a 25 deg. C heat-transfer table allowing the product to come to equilibrium.

From: "Lev A. Gorenstein" <lev#NoSpam.cv4.chem.purdue.edu>
Anyway, I think this is a good idea. Here's my contribution. These are "crazy phrases" from some works on several Moscow city and regional high-school chemistry olympiads (I've been a member of the Organizing Committee for them for a number of years and I really miss this now). By the way, if anybody knows about similar things here in the US (and Indiana in particular) - I will be gratefull.
Unfortunately, all of these citations are in Russian (obviously ;-) and, what is much worse, most of them are unexpected (for their authors) puns, which are impossible (at least for me) to translate (some of these puns were just great, all the Orginizing Committee was rolling on the floor in tears ;-). I found only several phrases allowing translation (not best pearls, unfortunately...):
[For the question: "Why H2S is a poison for us?"] : "H2S reacts with the iron in hemoglobin, forming an insoluble FeS, thus causing the oxygen deficiency" (there were some variants like Fe2S, Fe2S3, Fe2S2... But - isn't it a good idea, especially taking into account that it was in the work of a 13 years old guy?)
[for the question: "Why lead compounds are poisons for us?"] : a) "Lead ions make sugar in the blood poisoned" b) "After Pb2+ gets in the stomach, since there is the Cl- in the stomach juice, the reaction Pb2+ + 2Cl- ---> PbCl2 (s) occurs, and the unsoluble PbCl2 precipitates into the stomach, thus distorting food digestion"
"Also the produced hydrogen is a gas with nasty smell"
[At the end of the work] : "Damn, done!"
"When AgNO3 reacts with NH4Cl, there forms the precipitate kind of white and Ag salt" (Everywhere I tried to translate it equivalently to it's Russian prototype, saving the grammar mistakes and style ;-)
[For the problem "Find mistakes in the following procedure of preparation of diluted H2SO4: .... "] :
a) For preparation of diluted (strictly - solution) sulfuric acid one must not use concentrated H2SO4. b) There is no such thing as "volumetric flask" c) The mixture of ice and table salt DOESN'T EXIST!
"Ice and NaCl mixture? Crap! The ice would momentarily melt because of NaCl!"
"To the sulfuric acid one must add water, but not water to sulfuric acid"
[The following was on the VERY weak work (it happened that the teacher said to pupils : "You won't get a good grade unless you go to the olympiads" and sometimes there was just a bunch of people who were not interested in chemistry and had came only "to be marked good" in teacher's eyes). They were starving there, because they were unable to solve any problem, they couldn't leave because of a teacher, and they had to entertain themselves. But how? Probably the oldest way to entertain oneself is to write something nasty to somebody else (also proved by recent anonymous posting about grad. schools ;-). Ok, enough theory, I explained the joke, you may start laughing here :-) Okh, one more explanation: "pud" is an old Russian wieght unit, equals 16 kg:
"Don't have enough sake to find the mass % without calculator. That is
why:
It's better eat a "pud" of shit,
Than solve your chemistry, damn it!"
(this was rhymed! We thought about making this verse an unofficial slogan of our Committee ;-)
Will check in my books about any funny chem. experiments. Regards to all, would like to see other responces.

A Half-Ironman Triathlon consists of a 1.2mile swim, a 56mile bicycle ride, and a half marathon run (13 miles, 192 yards, one foot, six inches). Since Iron has atomic number 26, and alumin[i]um atomic number 13, would it be appropriate to describe Half-Ironman events as "Alumin[i]um Man" events?

Ok, here's one of my own...I ususally don't say anything quotable,
but a couple of my lab-mates thought this was pretty funny at the time...
Set up the quote: I am a synthetic inorganic chemistry student a Memorial
University of Newfoundland, St. John's, Newfoundland, Canada. Our research
group attempts to make interesting magnetic materials...not facile. After
a full week of null results at the bench, I had just found that my most
recent experiment had gone bust when a friend of mine walked in, finding
me scratching my head in bewilderment. With tinted bottles of solvents and
chemicals all around me, I just turned to him and said,
"All of these pretty little brown bottles surround me...and NOT A
SINGLE ONE OF THEM is filled with BEER."

But first they went to the lab, grabbed a bottle with the magic label 96%, and set off. After some time, the one said to the other: - I am afraid we have done something wrong. This is not ethanol, it is sulphuric acid. - I know. I have just peed a hole in he boat.

Oct 95) A scientist has come up with proof of something students have known for years -- chemistry lectures are boring. In an article published in the current issue of Chemistry in Britain, a university chemistry lecturer introduced a guest lecturer to a class of 50 doctoral candidates. Then, he and his colleagues studied variations in what he calls the HTFDR -- "head-to-floor distance reduction." After about an hour , the average HTFDR dropped from 135cm to 121cm, said the author of the study, who preferred to remain anonymous. The HTFDR immediately bounced back to normal when the speaker uttered the magic words: "And in conclusion............"

From: Ian Ellis <ian#NoSpam.iglou.com> ON A CHEMISTRY TEST at Midpark High School in Middleburg Heights, Ohio, one question concerned how to clean the floor after a chemical-powder spill. In detail, I described the liquid I would combine with the powder in order to dissolve it with chemical bonding and electron transfer. I was pleased with my grasp of molecular structure until the exams were handed back. Our teacher asked another student to read her answer. She suggested a broom and a dustpan to sweep up the spill -- and got full credit. --Contributed to "Tales Out of School" by Joe Astorino ऊ 1996 The Reader's Digest Association, Inc.

From: Ian Ellis <ian#NoSpam.iglou.com> DURING my freshman biology class at North High School in Springfield, Ohio, our teacher was lecturing on the conditions in which bacteria exist. Elaborating on the acidic environment where certain bacteria thrive, he suggested a simple experiment. "I want you to drop a nail into a glass of Coke or Pepsi, and then observe the acidic reaction on the nail," he said. The girl sitting next to me raised her hand and asked in all seriousness, "Do you mean a real nail, or a press-on?" --Contributed to "Tales Out of School" by Carolyn Stickney ऊ 1996 The Reader's Digest Association, Inc.

From: "V. ROGERS" <TEXVR#NoSpam.leeds.ac.uk> This was a story told to us by our chemistry master at school. A female student wished to make some potassium hydroxide solution (aqueous) and decided to throw a large lump of potassium into a bucket of water. Her professor observed what she was about to do, out of the corner of his eye and hurried towards her, and after confirming this was what she was intending to do, asked her first to stir the water in the bucket for five minutes before adding the potassium. She was puzzled and ran after him to ask the purpose of this action. 'It will give me time to get away' said the professor.

Whats that concoction?
My high school chemistry teacher, Mr. McKaskill was fond of making these
chemical concoctions and then checking out their properties. He would make
the weirdest combinations of chemicals with leaves, wood, basically
anything he could get his hands on. Once the entire building had to be
evacuated because he mixed up sulfur with some acid and something else
which even he cannot remember, producing hydrogen suphide in large
quantities. Whenever we came to his class in the morning there was some
new combination lying in some beaker somewhere.
Anyway, one day just before class I walked up to his table and picked up a
container of some red gooey liquid. Mr. McKasill had been working late the
previous day, so I thought that this must be the result of his work, so I
turned to him and said "Mr. McKasill, what is this muck. It looks like
diarrhea with blood in it" He turns around, looks at me with bleary eyes
and then says in a tired voice "Please leave that Prashant. Thats my
lunch."

From: "Pavel Goudochnikov" <ear9pg#NoSpam.WEST-01.NOVELL.LEEDS.AC.UK> A ubiquitous Fe-rich Male compound - FeMale - posesses a considerable number of beneficial properties. Frequently highly decorative in the native form, FeMale is a proven aphrodisiac and a versatile detergent. There are also reasons to believe that FeMale plays a crucial role in human reproduction and child-rearing. Despite the existence of vast archives of experimental data, the reaction pathways involving FeMale are at best poorly understood. FeMale is unstable in an oxydizing atmosphere and has been known to spontaneously ignite at room temperature. As a consequence FeMale is rather difficult to work with. The magnetic behaviour points towards polymorphism. It varies from sample to sample ranging from moderately antiferromagnetic to very strongly ferromagnetic. Curiously, some antiferromagnetic specimens appear to undergo a spin transition when exposed to alcohol-rich atmospheres (the well documented Beer-Goggles effect). Given the availability of reactive Fe, FeMale forms readily in Male- dominated environments and under favourable circumstances may persist over geological time. FeMale may thus prove to be of considerable importance on a global scale as an Fe- and Male- reservoir.

Background verification, two week cooling off period, fingerprinting, mandatory fizz locks. No gas release in excess of one liter. No automatic unloading - no motorized or wind-up Pez dispensors! CO2 kills! Suffocation! GREENHOUSE EFFECT! Save our children! Minorities are put at risk! I want a National War on CO2! We already know how Belgium was decimated by Coke-a-Cola. Can we afford to risk American lives so the small cliques of fantatics and zealots can exercise their bubbling pornographic appetites? How many children must die before we act! Burning the flag releases CO2, Hitler's crematoria released CO2, firebombing Dresden released CO2, nuking Hiroshima released CO2 - how much clearer must it be made? And what about NO2? SO2? ClO2? Are we about to discriminate on the basis of Period Table group number? Renumbering the groups ws not enough. Renumbering the groups will NEVER be enough! I say, "NEVER!" Every elemental group must realize its full electrochemical potential and oxidation state, and all its lesser oxidation states as well - with equal representation! Today it is baking soda and vinegar. Tomorrow it will be sodium hydroxide and concentrated sulfuric acid. By the end of the week butyllithium/TMEDA will be poured into Magic Acid by the pound! By the ton! WHERE WILL IT STOP! Exotherms, global warming, penguins sweated to death... all because some MONSTER wanted a little fizz.

From:: Franॉois D'Hooge <fdhooge#NoSpam.club-internet.fr> Yes, good ideas. I'll add some few more: Stop breathing. Every human release carbon dioxide by breathing, so, if 5 billon people stop breathing, we may go back to the ice age . Cut trees [at night] Well, trees transform CO2 into O2 by day, but when night comes, their evil CO2 producing task, begins. so, let's cut all trees at night. cut all the rainforest in a few nights. From: Pieter.Kuiper#NoSpam.itn.hh.se (Pieter Kuiper) In article <378F6C91.3EFAEB39#NoSpam.hate.spam.net>, Uncle Al <uncleal0#NoSpam.hate.spam.net> wrote in a beautiful outburst: > We already know how Belgium was decimated by Coke-a-Cola. Well, the company blamed that on "the wrong kind" of CO2....

From: mini-air <marca#NoSpam.chem2.harvard.edu> 2001-05-05 A Chemical Punch There has been a novel advance in the chemistry of propellants. Investigator Keith G. Tomazi reports: "I just came across a novel rocket fuel, as reported on Page 1 of the Wall Street Journal (Tuesday, April 10, 2001): The New York City-based Fighters' Institute for Survival and Training, or FIST, helps boxers with life outside the ring. But the group...hopes to become a union for boxers.... That pace sounds familar to Paul Johnson, a Minneapolis ex-boxer. He has tried to get the Boxer's Organizing Committee off the ground for about 12 years....Still, he believes that a union is imminent. "We've got the rocket ship on the pad, we're pumping liquid nitrogen, and we're going to blast off," he says. "This is one picket line that I wouldn't care to cross. Still, their chemistry seems unusual: I wonder if anybody else has proposed a non-flammable rocket fuel?"

CHEMICAL RELATIONSHIPS
Februari 14
From: "McCarthy, Devon" <DMcCa1#NoSpam.newhaven.edu>
My younger brother, worried he has doomed his relationship with his
girlfriend, came to me for some advice. I told him
Relationships are like titrations.
Just take it slow and don’t over react.

From: "Katrien De Gusseme" <katriendegusseme#NoSpam.hotmail.com> In second year of chemical engineering, I was following a course in industrial chemistry when all of a sudden, I see a friend on the row before me, standing up , pale as a sheet and trying to get out of the row of seats (mind you, it's one of those bigger teaching-rooms that seat about 150 people, we call them "aula's" in Dutch). The professor in fronts looks at my friend and asks what the problem is. "I don't feel well", he manages to say before he collapses to the floor. The professor, a man of impressive size, stays very calm and orders someone to call an ambulance. My friend regains consciousness but stays on the floor, not feeling well enough to get up. At this information, the professor turns to the blackboard an resumes his class. Some 10 minutes later the medics arrive, when they make their way to my friend, the professor turns away from the blackboard and says to them 'in the time it has take you to come here, a person could have died'. And he resumes his class again.
