    I I was in elementary school they had like a health fair fair or something like that one day and they set up this tent light thing that was dark inside and had Black lights in it and they gave us some go germ to put it on our hands after we washed our hands Then we went in the room so how dirty our hands were and then we came out wash them again and then we went in to see how clean they were it was cool

  • Dissa1

    In preschool our teacher taught us about germs using glitter! Apparently we (my twin brother and i) had our mom replacing the hand towels in the bathroom + kitchen every day and she wasn't happy 😆

  • ;-;

    is the four second rule real?

  • Firehawk3672

    "cut my hands off" no wait, she may be onto something there, with no hands, we cant grab stuff, and if we cant grab stuff we cant spread germs, BOOM problem solved!

    You could test: "Is it safer to be a bench warmer than the star player on your basketball team?" as it applies to the spread of germs. Have a player be infected and see how many others end up getting their germs, or fully contaminate the ball and see how many other objects (backboard, the ground from dribbling) get germs spread onto them.

    Here is my question. Why do we need a pandemic to be a reason to wash our hands. Should we not have been doing this all along? After you go to the restroom, before you eat, and when your done doing something that is messy like cleaning a horse stall? LOL

    You should wash your hands and then put the gloves on and see how much germs are on your hand. The gloves don't completely keep your hands clean

    should have put the blacklight on her face, to see how many times she touched her face. I know cali did.

  • fasfan

    So Calli is so offended that Grace hasn't seen Avengers and yet it was Calli who told her it was pronounced "Thanis" at first. Lol

  • fasfan

    How many people in the comments are correcting them that its "LEGO" and not "LEGOS".

    I'm certain I've already seen Alton Brown debunk the 5-second rule myth. And the funny part was, his experiment showed more bacterial growth from swabs taken off the floor than off of the sidewalk or the lawn.

    Grace was touching plastic bags of legos then using her teeth to open bags. Kelly after touching Lego touched her ear to move her hair. Should've black lighted those areas as they were secondary or even more and commentary

  • Timothy Fish

    The problem with the glow germ stuff is that it gives the impression that you are in danger from all kinds of ordinary activities. Part of the reason the five second rule works is because our bodies are capable of destroying small amounts of germs. Many of the germs in foods are destroyed by the acid in our stomach. It takes a while for most bacteria to reproduce enough to overcome our immune system. "5 second rule" is just an easy way to communicate that without saying that it is always okay to eat off of the floor.

    Fast fact: Everyone is horribly infected with viruses. Our DNA molecules consist of about 8% virus DNA that has been inserted into the strand. In contrast, the various genes that define who we are only take up about 1-2% of the space. The remainder is essentially a "library" of building manuals that tell the body how to build more DNA. Another fast fact: there are multiple types of DNA Something you wish you never found out: the bathroom is the cleanest place in your house (not because it's the most germ-free, but because we spend the most amount of time keeping it clean)
