Time to learn about disinfection(?)

It's only a hunch, but you wouldn't happen to be passing the buck now, would you? :unsure: :ROFLMAO:

Well, you could put that spin on it of course, but I'd say I'm probably out of my depth here.

Maybe we should return to your wooden spoon idea, or even regrettably suspending the Seniors Forum academy for the duration, if that doesn't work(?). 😧😮😟🙁.

Me, too, but my adage has always been, think big, even if your idea is small. :)

Your suggestions are brilliant! I love it!

As the old saying goes, two heads are better than one! :)

Its come to me..........a flash of genuine brilliance to generate interest etc., and if you cant guess what I'm on about, here is a clue: "We're already doing it!" 👨‍🎓.

No, go on tell me what my brilliant idea was, or you think it was.......?

I'm beginning to think it wont fly, and you may have had a truly brilliant one, given the level of confidence being shown(?). 🦋.

My dear Watson, you have captured the very essence of our deliberate plan, we shall press-forth and not be swayed by those who oppose us. Time is the teacher. Have faith. 🎩 🌂 💼

Best not to read it then. :)

Don't forget this is our best student so far, at the Seniors Forum academy!

Qudos, and top marks for trying to read the darn thing!🦶🖕🐛🐎🌎.(apologies, can't seem to remove insulting smiley No.2. :mad:!).
 
Okay, frivolous interlude over (lets hope!).

There is a very great serious to bear in mind obviously here, and anything anyone can learn about disinfection can only be a good thing cant it.

I felt I learned something from a quick search on the subject of soaps I'd like to share:

"Soap is a salt of a fatty acid[1] used in a variety of cleansing and lubricating products. In a domestic setting, soaps are surfactants usually used for washing, bathing, and other types of housekeeping. In industrial settings, soaps are used as thickeners, components of some lubricants, and precursors to catalysts.

When used for cleaning, soap solubilizes particles and grime, which can then be separated from the article being cleaned. In hand washing, as a surfactant, when lathered with a little water, soap kills microorganisms by disorganizing their membrane lipid bilayer and denaturing their proteins. It also emulsifies oils, enabling them to be carried away by running water.[2]

Soap is created by mixing fats and oils with a base,[3] as opposed to detergent which is created by combining chemical compounds in a mixer.

Humans have used soap for cleaning for millennia. Evidence exists of the production of soap-like materials in around 2800 BC in ancient Babylon."

Lots of good solid information, Graham! Thanks for it!

I recall way back in science class in high-school, I learned about the suspension qualities of soap, so an excellent refresher!

Bleach is a derivative of chlorine.

Thank you for the posts, Graham!

Am going to review this test once again to critique where exactly I went wrong.

How did you do on the test, Graham, and don't tell me you got 100%, because I don't like baloney sandwiches. 😒
 
Graham. With the vast numbers of those who got involved with this one, has a winner been established? I've been sitting on pins & needles every since you posted this, and still, no winner announced. The suspense is killing me. :)

Has such a pleasant ring to it, doesn't it... slightly below my score? :giggle: :geek:

All in fun, Graham! :ROFLMAO: :poop:

And dont forget I was trying to deal with "The American language" too! 🧙‍♂️✒🇺🇸 .

Yes, you're definitely head girl at the quiz, although a youngster attending school or college might expect 90% correct answers I'd guess, just to keep things in perspective.
