experiment

Nope didn't work.
Beware the grammar fiends on here - you should start with a Capital!! :) :)

I opened this expecting the post to explode, just like back in school.

mintos and fizzy drink experiment?

With a litre bottle of coke - yes!!

I recall an experiment with phenolphthaline at school. Turns out it's a pretty instant laxative!
Sorry Rob if you're reading this!

Making explosives in the Chemistry lessons is much more fun ;)

For those Old Boys of Leamington College, do you remember Mr Randall? We called him 'Twink' (he liked the younger boys). He did an experiment, which he took out in to the playground (we stayed in the classroom looking at through the windows). It involved a glass cylinder of Oxygen and one of Hydrogen. We spent most of the lesson sweeping up glass, after a fantastic explosion, watched from some considerable distance.
It it didn't involve an explosion, huge flames, or lots of smoke, what would have been the point?
-
In the sixth form we did an experiment to produce ether, and it involved venting it out the window using rubber tubing. Unfortunately I used too much tubing and it ended up venting into the Biology lab on the floor below. Also, unfortunately, it was whilst the biology lab wasn't being used, and someone had left a bunsen burner on. ;D
The explosion was spectacular, and resulted in the school being evacuated, even though the main damage was broken glass (windows etc)
The biology mistress didn't like me before the incident - she hated me after >:(. She tried to get me expelled, but failed as it was pointed out that it wouldn't have happened if the bunsen had not been left turned on.
She got her revenge though - I was the only person to get an A in A level biology(there were no A*s back then), but that was the only year there was no school Biology prize awarded!

My mate nearly got suspended for setting fire to a magnesium pencil sharpener with a Bunsen burner. The teacher threw a damp rag over it and it showered sparks all over the place. It burnt through the asbestos mat leaving a burnt hole in the bench.

We were making copper acetylide - bubbling acetylene gas through copper sulpate and forming a precipitate. Our chemistry master then demonstrated what happens when you take the precipitate and heat it on a gauze over a Bunsen burner. When it exploded, the gauze hit the ceiling at high velocity. A group of us were very impressed. He then said that silver acetylide was even more unstable. The following week we were back in the lab and acetylene and silver nitrate were at hand. Needless to say, we made some silver acetylide and pasted some around the 6th form common room door frame. We were hoping that some unsuspecting arty type would be the first one to open the door with the associated effects. Unfortunately, it was the deputy head!!! 4 of us hauled before the head and in no uncertain terms, told that we were very close to be expelled.

Nitrogen Tri-iodide crystals on the chem lab floor. Oh what fun.
-
My chemistry teacher was attempting to cut a small sliver of potassium to drop into a large glass container of water and accidentally dropped the whole thing in.
Broken glass and water all over the lab. Luckily no one was hurt.
He was the same teacher who managed to set fire to a large cylinder of hydrogen in class.
I don't think teaching was his true vocation.
-
Not school related, but in the late 60's I worked for a pharmaceuitical company in HW. In the manufacturing plant, they used potassium in one of the manufacturing processes. It was supplied in oil in 5 gallon drums. Some bright 'spark' decided to throw what they thought, was an empty drum into an effluent pit. Little did they know that there was still a stick of potassium inside it. Making waves was a very mild description of what happened next!

Sharing a car with my mate after he has had a curry tops the lot!!!!

Is that similar to a thermal lance?

Almost the same thing happened in one of my lessons, where the teacher was trying to cut a tiny piece of Sodium off and drop into a beaker of water, but a huge chuck fell off and stuck, balanced on the beaker's edge. We all legged it out of the room.
What else funny happened? Oh yes.
Why students should not tidy up after chemistry lessons. We were using charcoal to heat something. We were told to put back unused charcoal into the bag, and then into the cupboards. One of the pupils thought it would be a laugh to put his hot charcoal in the bag. About an hour later, much smoke ....
and we wonder why practical experiments are not often done in class these days?
-
Those were the days. Off to the local hardware and garden shops. Charcoal, sulphur, potassium nitrate, Jetex fuse and metal cigar tubes. What fun we had with those.
-
I will always remember an experiment back in the early 60s , making hydrogen, lots of glass tubes and beakers and the teachers words at the end, I will now prove there is hydrogen by lighting the end of this tube, he then proceeded to blow the whole lot to pieces covering the front of the class and himself with much sharp glass. Result teacher and several boys of to hospital, much blood and mayhem, those were the days.

My friend and I did something similar and burned a large section of the window sill in his bedroom.
Our mothers were furious, but his dad was really pleased we'd managed to get the ratio right.

My dad decided to make gunpowder in his parents' newly decorated front room. It didn't end well with burned hair and stuff. At least my grandparents had the chance to decorate again, and new windows!
I spend my days looking at chemical processes, trying to keep everything in the equipment and stop them blowing up. It's a fun job except when I get to see explosions they rarely end up well.
-
No chemistry experiments to tell of, but I have seen a frigate accidentally fire off a dummy torpedo round across the jetty, only for it to collide with and write off some poor individual's car. That was quite disastrous.......and quite a story to tell the insurance company.

I have been in a lab fire with Na-K alloy plus diethyl ether, which was not fun, nor especially my fault, although I did put that one out and hit the alarm.That evacuated an entire building, putting my future wife out in the rain. We met that night where I had to explain that she got soaked because of me. :-[
Once my students managed to evacuate a wing of a school when one ignored the instructions making copper sulphate via sulphuric and copper oxide, heating unneutralised acid to form acidic plumes. Think that was my third week in that school.
I once dunked a bit of sodium accudentally- it hit the ceiling with a huge bang, making a girl in the front scream and possibly wet herself. I have had a couple of ethanol fires, again due to potassium, evacuating the school but only as a precaution you understand, and burned a hole through two heatproof mats into a wooden bench with charcoal blocks used in the extraction of lead from lead oxide. The mark is still there, and nowadays we use five mats.
During my A levels I got concerned sulphuric on my trousers and shirt leading to a rapid removal of clothes as it ate through them. Also threw away some phosphorous chloride down the sink which is not to be recommended.
When working for Mobil I saw a heated bitumen canister lose its lid and fly across the room into the wall, that was my bad, not putting holes in the canister first.
I have seen Lithium Aluminium Hydride go up from a washing up bowl, which really should not happen. Had a few halogens go haywire.
I won't mention chlorate bombs.....
Strangely despite all this and more I ended up being my school's health and safety officer....

After reading this thread - most of which I don’t understand - I’m very glad I gave up sciences as soon as I could. I wonder if there is a correlation between irresponsible/innocent schoolboys & Wasps supporters? Probably not.
My only contribution is having a client with a big City office who allowed staff to have Amazon deliveries to the office to make sure they didn’t stay at home. One day a large delivery arrived of some chemical or other - note comment above of my ignorance - & along cane the police too to check what it was going to be used. Turned out to be an innocent need!

Did you get notification of being smited? I only noticed a few weeks ago the applaud/smite thingymajigs, but I've no idea when they happened or for what post........
-
No, I just happened to notice as I had a screenshot of this morning on another machine and saw the difference. My chemistry anecdotes often have this effect, especially on my wife..... :) :
I mean technically it could be another post, but they are mainly morning alls and other harmless offerings of late.

Somebody must have been badly traumatized by Chemistry lessons at school, but not me.
I was badly traumatized by the WHOLE school experience. I still have nightmares about school, some 50 years later.

Hahaha, and right on cue, I've received my first smiting!! I feel I have some street cred now....... ;D

Just noticed so did I.
Looks like you might be correct - the old arts v science rivalry for the online generation?

If you click on your profile you can see the numbers on a phone, or switch to desktop mode. My old phone chopped off most of the profile and two buttons, so you could not use them even if you wanted to.
