If the sunscreen is zinc based, they should be fine. If the sunscreen is carbon based, the UV will just heat it up and they’ll either incubate or die trying.

Yeah, in school, even when I worked with piranha solution or aqua regia I didn't really wear gloves. The only time we did was for hydrogen fluoride.

How did you quantify the amount of bacteria left over? Like is there a way to compare the growth of the control side and experimental side? Not sure if that makes sense, but thanks
Hi Katie, Usually you can count the number of bacterial colonies and compare the different sides. Highly concentrated cultures often leave a "lawn" of bacteria which we can see in the control side. Hope that helps.
You can literally see the living bacteria with the naked eye. Couldn't you see the difference between the sides? And he was just counting how many separate groups (colonies) were remaining. Just the number of colonies and total size (area, because they're on a very flat surface) should be all we care about.... not the actual number of bacterium left over.
Thanks the video is a boon to explain community the effect of time and UV radiation on harmful ecoli found in so many water and food items we consume daily.
What if after being exposed the the UV light, you look down is shock as the E. coli takes of a pair of shades and says “Hey! Thanks for this nice, golden tan!”
I honestly love watching bacteria colonies grow, it’s my favorite thing to watch, it’s interesting to see this though. It reminds me of my science fair project, how much bacteria does make up contain? I had a lot of fun watching the progress of the bacteria colonies and seeing them grow, it was very fun. I would like to try this one day at my schools lab, maybe with something different.
thanks I have 13w uv light.. I submerge it into my water dispenser for drinking.. I was wondering how long to turn on the disinfection cycles.. now I have an idea..
Anyone else freaking out about him not using gloves while handling the E. coli? Lmao. My microbiology teacher always made sure we handled our Petri dishes with gloves.
I have thought of an experiment involving this method. I'll cover a plastic wrap above the petri dish after inoculation where I can apply a handful of sunscreen. In theory, this should filter, or at least some, UV rays; thus having more growth compared to those completely exposed to UV. It would be nice if you have an insight to this matter.
I hope you wore proper eye and skin protection when using UV-C bulbs! Even brief exposure can cause temporary damage, and anything more than a few seconds can cause burns in your eye. Apparently it feels like you have sand in your eyes all the time... some people's eyes seem to recover, others have irreversible damage. All depends on length of exposure and the power of the lamp. Best to just not take any chances. Even standard polycarbonate safety glasses cut pretty much 100% of UV-C light but even though I know it's factually true it still doesn't feel safe to me and I tend to use specialized UV blocking glasses. For those wondering, the reason UVC is so dangerous to humans is that we are never exposed to it naturally. The sun does produce quite a bit of UVC but the atmosphere filters almost all of it out, as well as most UVB. The UVB that gets through is what causes tans/sunburns/melanomas. UVA does also play a part but it's not nearly as damaging as the shorter wavelength UV.
I know this may sound a bit insane, but if only we could do this same experiment but with even stronger EM waves to test how long microbes could withstand, like say, X-Ray.
This is what I was also wondering. Ozone is heavier than air so it will fall down onto the uncovered side of the petri dish. Perhaps they could seal the dishes and remove all oxygen.
0:40 "One half of the petri plate is covered to protect against the UV light. The right half will be the control side." sounds like they are two different sides and is very confusing actually
can anyone tell me what is the best uv wand to get i want to make sure it's not a knock off and it kills the bacteria and i want one i can change the bulb if possible for toilet bed sheets and kitchen counter and my lazyboy. how would a person go about testing if it kills germs as it should.?
it s not good to use UV light to kill bacteria in closed area like your toilet, because Uv light reacts with Oxigen O2 in the air to form ozone O3, which is toxic!
i recieved a light in the mail with no instruction it is led and it is blue it showed how what surfices needed to be cleaned I think it is a black light. Is there such thing as a led uvc light?

Eh, the bacteria used in a lot of labs are non pathogenic, and if you use proper sterilization, handling, and clean up techniques it’s fine. You can use gloves for extra protection though (I generally do because I’m clumsy sometimes)

How about uv sanitizing tubes that are used to purify water? The range of the light to the water is point blank. Can you make a content about this? Does uv sanitizing tubes really work?
John Olson it does work, but it also kills everything else. Using UV light to treat Covid in a person makes about as much sense as boiling them to sterilize them.
That’s interesting. It shows why spraying streets & pavements in complete nonsense. But I wonder (obviously in context with The Virus): how useful is UV (suppose it’s UV-C, right?) when it comes to disinfecting surfaces (in a shop, train, bus etc)? Does indirect exposure kill? How do I find out the right exposure time? What wattage is needed?
So to protect myself from bacteria I just have to stand under an extremely intense UV light source for extended periods of time. Maybe if UV kills bacteria, it can also kill skin cancer. I think I just earned myself a noble prize.
Is there a way I can do a similar test, but not E. coli? Preferably something that I can safely obtain. I have my own UV sanitizer light, but I don’t know if it works properly.
I am not sure. I used a lamp that had two 15 watt bulbs for this video. My guess would be the 3 Watt lamp would require more time to kill the bacteria. If you have access to a microbiology lab, you may be able to test the 3 watt lamp it.
Not mentioned here that the UV light needs to be UV-C light. Not UV-A or UV-B. A or B will not kill bacteria or viruses. That’s a very important note not mentioned.

It might be somewhat stupid but why don't we use UV light in our fridges to reduce decay? I don't think it'd cause any problems for its nutritional properties since we digest everything into its smallest parts anyway
what if all the bacteria just ran away to the other side?
E. coli can't move on a solid medium. It would take them a very long time to move to the other side as well.
