What cheeses me off

[Quickstatus]

the gas in the taps wasn't the deadliest gas in the room.

We had comps to see which one can sustain the flame the longest

Anyone try the mentos in Coca Cola?

Burning asbestos mats and setting magnesium on fire. The good ole Chem lab days.

Its all good and fun until it isn't - I loved chemistry and used to run experiments learnt in class at home in dad's shed from materials I bought from a school chemistry supplies outlet..

One night I made a quantity of hydrogen (from acid) and filled a balloon, tied it off with a long strip of magnesium ribbon, lit the ribbon, and released the balloon. Great fun with a big flare in the sky and then minutes later a bang (which was reported in the local newspaper as a possible ufo sighting). However, went back to do it again and got the mixture wrong and the beaker of acid exploded its contents all over the inside wall of the corrugated iron shed. Lets say, dad was "not happy Jan". That was the end of chemistry experiments in the home shed.

Doing experiments with cigarettes, burning them through a plunger and a filter paper to see how much cough went into your lungs.

And in an all boys school, the gas in the taps wasn't the deadliest gas in the room.

Not school, but in med school physiology practical, we had one student take a GTN tablet, one smoke a cigarette and one take an amyl nitrate popper to observe the effect of nitrates. Sure its not happening now

The common expression is % (mg/ml) because we actually want to now how much of x is in the vial.

So if a vial is a 1% of something and the vial is 10ml, we automatically know it contains 100mg (unless you are a med student). PPH would just be unworkable

pph is %, for anyone who understands...

In any case, it's a ratio - meaning there are no units. or perhaps the units are irrelvant. it's a ratio.


mumble mumble - moles/L

Oh, for the good old days in the chemistry lab! Gas taps easily turn-onable and Bunsen burners to hand; conc HCl and H2SO4 was in the back of the fume cabinets, copper coil in the cupboard. Magnesium ribbon was locked away, but you could usually snaffle a bit extra during class and use it afterwards. Thankfully not silly enough to fool around with the phosphorus ...

Yeah, I actually scored the makings for nitro glycine from chemistry class at school.
After some research, decided against trying to make something that is extremely temperature and humidity sensitive in a Queensland backyard.

Had a mate who scored a cube of sodium - he has the scars to prove it...

anyway chemistry was never really my thing. The chemists fit into two categories, the ones who made explosives and the ones who made drugs.

pph is %,

Sure, but that is not the common nomenclature for the profession.
Gotta speak the lingo

Similarly, needle size is in Gauge which is an imperial as one can get. No one is ever going to change to mm diameter
Patients sometimes get worried - they think the 25gauge needle is bigger than the 16gauge

Patients sometimes get worried - they think the 25gauge needle is bigger than the 16gauge

Let me tell it from the patient’s point of view. I don’t give a rats bottom about the needle gauge (don’t they measure shotgun barrels in gauge?) I just know big is bad and small is better.

And small isn’t great when it has to traverse sideways with ultrasound guidance in your palm as they put steroi_ into an inflamed tendon sheath

 

[Quickstatus]

I just know big is bad and small is better.

The other way round. The smaller the gauge the closer the needle to a shotgun barrel in size. .

Then there is the French gauge for catheter sizes. The French are smarter so the bigger the number the bigger the catheter.

Bought a new Samsung fridge 2 days ago and delivered yesterday. Wife noticed today that it's not sealing properly and one door closing causes other door to open slightly. Unbelievable.

Called and Siam TV came out and we convinced them to give us new fridge not fix the seal. They took the fridge away and will deliver another tomorrow.

Now called and new fridge coming tonight. Stress.

I was talking about needle size (in absolute terms) - as I mentioned, don't care about 'gauge'.

Wife noticed today that it's not sealing properly and one door closing causes other door to open slightly. Unbelievable.

That's not surprising, surely? When you close one fridge door, especially other than slowly, you are pushing air into the fridge. Air has to go somewhere, so pushes the other out a little. Similar to opening one door of a house, letting wind in, causing another to slam shut.

Late 50's , was able to order saltpetre and sulphur ( among other things ) by the pound from a Melbourne chemical joint and have it sent out into the bush through the post. Another kids plumber father mate made the tin rockets..
We later moved on to adult entertainment with gelignite and dets

Everyone knows the SI unit for weight is the elephant… “that tram weighs the same as five elephants”; “the new Range Rover weighs half an elephant”!

They also know the size for aquatic ‘acreage’ is the Sydney Harbour… “the introduction of water saving measures has reduced annual water consumption in our city by two Sydney harbours”

What’s the SI unit for going off topic?

And here I was thinking it was rhino...

 

[mel-world]

This is just getting so OT that I might just have to unwatch what was an entertaining thread. I'm so over SI!

A reminder that this is the 'what cheeses me off' thread. Not what I did at school.

Back to the thread topic please.

What I did at school cheese me off!
Although Adam Hills was in the year ahead of me, I recall when I was in about Year 8 he & a bunch of mates were walking in front of me & he made some musical underwear joke about A-Strings and G-Strings and I thought it was absolutely hilarious!

Trying to find an annual domestic multi trip travel insurance. Click on links and then it says no your dates don't qualify so maybe you could use a multi trip policy. Yes idiots that's what I clicked on - more than one insurance company too

What cheeses me off is half of

what I did at school.

had no utility afterwards

What cheeses me off is a flat battery in the car this morning.

Cheesing me off even more: the warranty on that battery ran out less than two months ago.

Yes it's amazing how well they can calculate the warranties of car batteries isn't it! I'd still make a claim on the dealer / battery company.

Yes it's amazing how well they can calculate the warranties of car batteries isn't it! I'd still make a claim on the dealer / battery company.

And not just car batteries - in recent times I've had a toaster expire 2 weeks out of warranty, a hairdryer expire 1 year out of warranty - which I know sounds bad, but I would be lucky to use it 3 times a year, so hardly heavy use, and an Aldi power tool give up the ghost a couple of months out of warranty. I tried on all of them - toaster was replaced, Aldi refunded on the power tool as they couldn't replace it which I thought was totally amazing, but hairdryer said no. I suppose technically fair enough, but really if a hairdryer carks it after no more than 5 uses, it is not really fit for purpose.
