Glass Half Full, but 90% WOULD BE BETTER

I just, for the sheer hell of it, weighed the contents of a can of Woolies home brand Kidney Beans, while I was fixing up a mess of chilli for dinner.
The can says 400g, but the beans totalled about 240g after draining. That would have been even less if I had surface dried them.
So you Woolies shareholders owe me! Thieves!
That said, are there any other common products, outside the supermarket space, that you know of where blatant short supply is normal?

You guys ought to watch Today Tonight on Channel 7 they do stories about that sort of stuff a fair bit. The other week they did this story about some chick who dyed her own hair and she went bald - fricken interesting.

yeah they were really good with that facebeef mess also credibility of zip.

I was suspicious of our local servo's pumps and decided to do my own measurements. Apparently, volume of petrol fuel can change with temperature and or atmospheric conditions. So measuring by volume is not consistent, but measuring by weight is. One litre of fuel should always be consistent in weight(about 732grams).
Used a commercial battery operated scale and the weight was spot on.
Fuel retailers are inspected regularly and their pumps are tagged.

You've actually got that backwards - one litre of fuel is always one litre of fuel. So if you fill 5 litres of fuel into a measuring jug at the servo you should get exactly 5 litres of fuel. (Different story if you then allow that one litre to warm up or cool down between the two measurements).

Meanwhile, the weight of a litre of fuel is dependant on the temperature you've measured it out at.
Secondly, petrol is made at a refinery by blending several different components - the weight of a litre of fuel will vary considerably from batch to batch.

Would love some elaboration on this. I'm under the impression that the volume will vary with temp (as in any liquid I can think of) but the mass will remain constant (ignoring evaporation)???

It's definitely lighter from when I was a kid !!!

There's no more lead in it and we all know how heavy lead can be....

No a kilo of petrol will always weigh a kilo - no matter what.
A litre of petrol will weigh a different amount based on the temperature. - Now this is not saying that you get a litre, change the temperature and it will weigh different no - it will weigh the same becuse there is the same mass of petrol in the container. But if you measure out a litre of petrol at 5 degrees and measure out a litre at 30 degrees yes they will weigh different. But they will both still be a litre!



Yes you are correct - thats what I said.

Just to clarify: mass and weight are both measured in grams and kilos. Mass can change with temperature and weight remains constant. So therefore: measuring mass or volume is temperature dependent, but measuring weight is consistent regardless of temperature.
I still do not understand how, as you state "You've actually got that backwards "

And this brings us to the Higgs boson which I'm sure all seabreezers would know,gives mass to objects .Now here's a thing now that they have found it, how long before they learn to remove the mass from an object which if you could do to a space ship or volkswagen would allow you to travel at the speed of light across the universe on a litre of fuel regardless of the mass. It would still be a litre of fuel.
Or would it ? (Plays x file music in background]

My local Caltex sells E10 as Vortex... c**ts.
I know this cos my car pings with E10.

I'm sure it was a one off mistake.
