Very dangerous mix
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.

Fight against CO2
Isn't it time we required universal Federal licensing for use of Alka Seltzer, Fizzies, and Pop Rocks? 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. Isn't that the way it always starts, with a "little" CO2 in a Bierstube in Munich? Computer models and their renormalized data are unequivocal: 44.0104!
Mommy, daddy, does your child breathe CO2?
Put an end to the CO2 nightmare before it's too late!

Chemist's last words
The last words of a chemist:
1. And now the tasting test.
2. May that become hot?
3. And now a little bit from this...
4. ... and please keep that test tube alone!
5. And now shake it a bit.
6. Why is there no label on this bottle?
7. In which glass was my mineral water?
8. The bunsen burner *is* out!
9. Why does that stuff burn with a green flame?!?
10. *H* stands for Nitrogen - and that does *not* burn...
11. Oh, now I have spilt something...
12. First the acid, then the water...
13. And now the detonating gas problem.
14. This is a completely save experimental setup.
15. Where did I put my gloves?
16. O no, wrong beaker...
17. The fire alarm is just being tested.
18. Now you can take the protection window away...
19. And now keep it constant at 24 degrees celsius, 25... 26... 27...
20. Peter can you please help me. Peter!?! Peeeeeteeeeer?!?!?!?
21. I feel it how long 15 seconds are!
22. Something is wrong here...
23. Where do all those holes in my kettle come from?
24. Trust me - I know what I am doing.
25. And now a cigarette...

Thrown out of the lab
Top Ten ways to get thrown out of chemistry lab
10. Pretend an electron got stuck in your ear, and insist on describing the sound to others.
9. Give a cup of liquid nitrogen to a classmate and ask, "Does this taste funny to you?"
8. Consistently write three atoms of potassium as "KKK."
7. Mutter repeatedly, "Not again... not again... not again."
6. When it's very quiet, suddenly cry out, "My eyes!"
5. Deny the existence of chemicals.
4. Begin pronouncing everything your immigrant lab instructor says exactly the way he/she says it.
3. Casually walk to the front of the room and urinate in a beaker.
2. Pop a paper bag at the crucial moment when the professor is about to pour the sulfuric acid
1. Show up with a 55-gallon drum of fertilizer and express an interest in federal buildings.

Biologist experiment
There was this biologist who was doing some experiments with frogs. He was measuring just how far frogs could jump. So he puts a frog on a line and says "Jump frog, jump!". The frog jumps 2 feet. He writes in his lab book: 'Frog with 4 legs - jumps 2 feet'.
Next he chops off one of the legs and repeats the experiment. "Jump frog jump!" he says. The frog manages to jump 1.5 feet. So he writes in his lab book: 'Frog with 3 legs - jumps 1.5 feet'.
He chops off another and the frog only jumps 1 foot. He writes in his book: 'Frog with 2 legs jumps 1 foot'.
He continues and removes yet another leg. " Jump frog jump!" and the frog somehow jumps a half of a foot. So he writes in his lab book again: 'Frog with one leg - jumps 0.5 feet'.
Finally he chops off the last leg. He puts the frog on the line and teels it to jump. "Jump frog, jump!". The frog doesn't move. "Jump frog, jump!!!". Again the frog stays on the line. "Come on frog, jump!". But to no avail.
The biologist finally writes in his book: 'Frog with no legs - goes deaf'

The astronomy jokes
NASA just disclosed details why the rover wouldn't accept any commands. They took a picture of the rover's built-in display which showed a windows screen and the text "press any key to continue".
It is not conclusive yet, but the NASA believes the Mars Pathfinder has found proof of life on Mars. The cd player was stolen.
The Mars Pathfinder was renamed today in honor of the late astronomer, Carl Sagan. The craft will henceforth be referred to as bha memorial station.
You've probably heard about the Mars Pathfinder probe. Once it lands on the red planet, pathfinder will release the sojourner rover, a little laboratory on wheels. Sojourner will cruise about the martian surface performing experments. It turns out that sojourner and pathfinder will communicate using two standard, off-the-shelf 9600 baud radio modems.
According to jet propulsion laboratory program manager Donna Shirley, the modem manufacturer warned jpl that sending the modem to mars would void the warranty.

Reasons for the Mir Accident
After intensive investigation on both the Soviet and US parts, spokespersons from both space agencies have determined the cause for the accident which has placed the station and its resident personnel in jeopardy.
In terse statements at a recent press conference, Soviet and US space agency spokespersons said Thursday We have concluded joint investigations concerning this potentially tragic accident and each nations' team, separately, has arrived at identical conclusions for this incident.
The accident was caused by one thing and one thing only: OBJECTS IN MIR ARE CLOSER THAN THEY APPEAR.

Administratrium, A New Element!
Administratrium, The New Element
AMES, IA--The heaviest element known to science was recently discovered by materials researchers at IPRT/ISU. The new element, tentatively named Administratium, has no protons or electrons, and thus has an atomic weight of 0. However, it does have one neuron, 125 assistant neutrons, 75 vice neutrons, and 111 assistant vice neutrons. This gives it an atomic mass of 312. These 312 particles are held together in a nucleus by a force that involves the continuous exchange of particles called morons.
Since it has no electrons, Administratium is totally inert. However, it can be detected chemically, since it impedes every reaction it comes into contact with. According to its discovers, a tiny amount of Administratium caused on reaction to take over four days to complete; the normal reaction time is less than one second.
Administratium has a normal half life of approximately three years, at which time it does not actually decay, but instead undergoes a reorganization in which neutrons, vice neutrons, and assistant vice neutrons exchange places. Studies have shown that the atomic mass usually increases after each reorganization.
Research at other laboratories indicates that Administratium occurs naturally in the atmosphere. It tends to concentrate at certain points, such as governmental agencies, large corporations, and universities. It is always found in the newest, best appointed and best maintained buildings.
Scientists point out that Administratium is known to be toxic at any level of concentration and can easily destroy any productive reactions where it is allowed to accumulate. Attempts are being made to determine how Administratium can be controlled to prevent irreversible damage, butresults to date are not promising.
