Ok... this has got me beat. Clear green liquid. Clear nozzle.

Hit plunger, this white foam comes out.

Sorry, but Bealman no comprende.
What's the go of that? :confused2:
Presumably the pump and nozzle aerate the liquid to an extent that the quantity of the liquid in the foam is so low that the colour is almost indetectable. It may also be that the bubbles in the foam are very reflective, thereby giving the white appearance.
It's the same with the old-fashioned Fairy washing up liquid - a dark green liquid but all the bubbles that are created are white - as well as keeping mummy's hands so soft, according to the adverts ;)
I remember those old adverts. :thumbsup:
It's disconcerting to me, though. Almost magic. :uneasy:
Suppose it's a bit like grinding clear glass up - you end up with white powder. Likewise you put white solid salt into water and you end up with clear liquid.
But the scientist side of me agrees with you.... it's aeration. I just didn't think of that because it took me by surprise. I was expecting sticky green liquid!
Still bloody magic. :beers:
Quick, someone do that thing where you wobble a pencil side to side and it looks like the pencil's gone all floppy, let's see if we can tip him over the edge!
;D
Excellent, that'll fox 'im.
;)
Trying to soften your cuticles again, George? ;)
Sorry, but the pencil was a trick I learned from the Eagle comic a long time ago.
I would demonstrate it to my students in my teaching days.
As putting your index fingers together but focussing past them.
You will see a sausage which gets shorter and floats in mid air when you pull yer fingers apart. :thumbsup:

Have you been drinking that hand wash? :smiley-laughing: ;)
Try it!
Put your index fingers tip to tip, six or so inches from your nose, you'll see a sausage!
Take them apart, the sausage shrinks and floats in midair.
Go easy on 'im, lockdown's been tough.

Oh!

You got one from me and, presumably since nobody's come up with another nor contradicted mine, it must be correct :thankyousign:
Having had a few beers, I'll go to bed.
All that's on telly here is BBC shows like Midsommer Murders anyway ;)

Don't you know if there are any chemists there? ???
We have lots in Leyland but not many are open on Sundays.
From the internet, so it must be right!
Foaming Hand Soap. Truth be told, foaming hand soap is a form of liquid soap. It is derived from a diluted form of liquid soap that is infused with air to create a foamy lather as it leaves the dispenser. ... One chamber holds soap and one pumps air into the dispensing unit when the pump is depressed.
...and
Is foam hand wash better?
The research team suggests foam soap may be less effective than liquid soap because it comes out of the pump as a lather, whereas the liquid soap lather is built up in the process of hand washing. Also, the amount of soap in foam is markedly less in a single pump than is found in its liquid counterpart.

Which begs the question, apart from the UK, which other English speaking (and I use the phrase advisedly :D), countries, refer to the place where medications are procured as a chemist's shop?
In the US it's a pharmacy.
How about Oz, Canada, etc, etc?

I think they are being called that more in the UK too - I suspect the reason for the term "chemist's shop" is a hanging on from when such stores actually sold chemicals of all sorts, rather than just stocking pre-packaged preparations.
In the USA I thought it was a drugstore?
We have "Chemist Warehouse", "Chemist Outlet" "Priceline Pharmacy" and fortunately still some compounding chemists who can make up your mixture or emulsion if required.
Chemicals and "the Chemist" appear to have different connotations these days!
My mate Al is a chemist, but he's busy with some project to transmute base metals into gold.
I dated a chemist once, but it didn't last long - we never bonded.
I'll get my lab coat.
Al Chemist indeed. :smiley-laughing:
I'm off out with me two mates Nick Otine and Al Cohol.
Guess there has to be some chemist ry

"Drugstore" seems to be falling out of use, certainly, at a doctor's office they will ask 'which Pharmacy do you use?', and the actual locations themselves are always called Pharmacies, whether they are in a larger store, like Walmart or standalone, like Walgreens (no relation) :)

Ahhh, Wal-Mart. The ultimate one stop shop. I love the place.
