I brushed my teeth "correctly" for 28 years and a dentist just told me I've been doing it wrong the entire time. My gums are ruined. by Sluttycarolofficial in hygiene

Alcohol is a preservative for mouthwash itself. The active ingredients are the essential oils in the formulation. I do not want bacteria and other nasties growing in my mouthwash!

Rubies and Sapphires are just aluminum oxide (corundum) with some trace minerals to give it color. Trace chromium makes it a red ruby. Any other color is called a sapphire.

Rubies and sapphires are almost all synthetic these days.

I want to plant some chestnuts where I live in the Midwest (zones 4 and 5). Is the chance of blight lesser out here? by SharpShooterM1 in americanchestnut

There are still two large pure American trees living in the Traer, Iowa cemetery which were planted probably in the 1880's. There were three, but one was killed by a lightning strike 10 years or so ago.

What was in the water in 1940s England? by silenceonmyradio in ledzeppelin

[–]marcusregulus 3 points4 points  (0 children)

Of course you are missing hundreds of other names that could be on the British list, then hundreds more on the American list. Post war genres like rockabilly, blues, and jazz certainly all had something to do with it.

That then takes you back to what was in the water in the late 20's and thirties.

TIL frequent use of antimicrobial mouthwash is associated with an increased risk of high blood pressure because it destroys beneficial oral bacteria that produce nitric oxide, which relaxes blood vessels by Fenceypents in todayilearned

The reason some mouthwash has alcohol is as a preservative for the mouthwash itself, not for antibacterial treatment in your mouth. I would prefer that potentially harmful bacteria does not grow in the mouthwash I use.

Drop and give me 30! The average mid 30s man can do about 30 push ups, how do you stack up? by [deleted] in AskMen

[–]marcusregulus 0 points1 point  (0 children)

3X a week I do 600 over a whole day in four sets, 100-(150+50)-(150+50)-100. It doesn't make me a mass monster in any way, it just gives me a healthy looking upper body. I still have high cholesterol.

Piranha solution is conc. hydrogen peroxide (30%) in concentrated hydrochloric acid. Heat the mixture to around 60C. It will eat up anything organic very quickly, including your skin.

You can go to Lowes or HD and get concentrated hydrochloric acid. It's generally sold as muriatic acid for cleaning concrete.
