    So, I was talked into testing out lime juice this time on the pond water, and found out that it caused the bacteria to stop moving (apparently, the acid destroyed the membranes).

    I wonder if acid would destroy viruses.

    Edit: yes it would, alcohol is used as an anti viral

    Shifting the PH balance far out of normal boundaries kills most things, acid or alkaline, either works as well. Lemon juice and vinegar are both acidic, chlorine bleach is alkaline, none of them are much good at breaking down oils so that dirt will shift easily. Different types of "clean".

    When I mixed the pond water with vinegar, I was surprised that it stopped the bacteria from moving (now I know why my mother used it to clean the floors).

    So, this time I mixed the pond water with hand sanitizer, and well, all the bacteria stopped moving instantly (more than 99.9% effective).

    No surprise to me...lol. Some hand sanitizers can be pretty scary stuff apart from the bacteria they annihilate.

    Be aware that even if they stop moving they may not have been killed. Death by sanitizing or sterilizing agents is a stochastic process over the time of contact. After your tests, you may want to put a sample into some beef broth to see if it grows up.

    I used to test sterilization and aseptic processes for parenteral (injectable) drugs for assurance much less than the probability of outputting one non-sterile unit in a million using extremophile bacteria resistant to; heat sterilization- both dry heat and steam, filtration, radiation, or vapor agents like ethylene oxide or hydrogen peroxide.

    So, I got more pond water and mixed it with dish soap. It was not as effective at getting rid of bacteria as I thought. A few of them survived, so dish soap washes not eliminates.

    If it's a "biodegradable" detergent it will feed bacteria rather than kill them. That's what biodegradable means.

    You also have to consider different brands of dish soap, and whether or not they have ingredients to be more mild regarding human skin conditions. Much like some hand soaps which can be horrendous on other parts of the body intended only for the hands, with maximum anti-bacterial action.

    That's interesting. Now I know why during COVID they brought out an antibacterial dish soap. (Not that it would it would make a difference to COVID, normal dish soap would kill it anyway. I think we became slightly sterile obsessive during COVID though so it was a good market opportunity)

    I expect the mechanical action of scrubbing the dish will disrupt any bacterial colonies that could make you ill.

    So, I mixed some cinnamon in some of the leftover pond water that I have, and was surprised to find out that the bacteria had stopped moving. Interesting.

    Keep at it. I find your observations to be fascinating, especially over common substances. :cool:

    Well, I mixed pond water with salt, and I realized why there wasn't much bacteria in sea water (the salt caused them to stop moving).

    Sea water in the tropics is full of bacteria. In temperate climates bathing wounds in the ocean is a good idea, try that in the tropics and you could end up with a nasty necrotic tropical ulcer.

    They use salt to preserve things don't they. Now is it the salt that stops bacteria or is it the drying out/ dessication. @Outdated seems like salt isn't anti bacterial then, or not 100% effective
    Levelskid
    Salt crystals are surprisingly intricate. Going to mix it with pond water next (thankfully, it stopped raining).
    Levelskid
    I mixed detergent with some pond water, and the bacteria melted faster than alcohol (it's like watching them turn into soup).

    ¡Hey amiguis!

    I really like these posts, have tou tried looking at a feather under the microscope?
    Levelskid
    Levelskid
    Yep :)
    Levelskid
    Needles are really dull up close, and based on the amount bacteria on it; it's best to sterilize it with alcohol.

    There's a surprising amount of fungi in the dirt of your nails (this is why I keep my nails short and manicured).

    Was that your most recent microscope experiment? I was learning how to examine soil samples the other day.

    You'll find that fungi all over your body if you're healthy. It's the first line of defence in your immune system, kill them at your own peril.

    Lotion look like water droplets when viewed through the microscope. I wonder if different brands would look any different.

    Well, I look at some orange juice (with pulp) through the microscope, and noticed some square shaped cells still in the juice. Looks like we're still ingesting plant matter.
    Levelskid
    So, I look at yogurt under the microscope, and saw plenty of bacteria (most of them are probably beneficial).
    Levelskid
    So I took the pond water and mixed it with bleach this time, the bacteria stopped moving, some just melted, and a few other creatures just shrank for some reason.

    Chlorine breaks down oils by physical reaction - acidic versus alkaline.

    isn't that saponification, in that one?

    Using chemicals has long term consequences while alternatively natural selection has made it possible to address such issues and without having the cost of buying chemicals. Please, learn about natural options. It allows you to make your choices away from our current colonialism and capitalism norms!
