Expensive VS. Cheap Sunscreen - Proven With Science

- Опубликовано: 7 авг 2019
- For this summer science experiment I wanted to know if expensive sunscreen such as banana boat and coppertone and hawaiin tropic sunscreen worked better than the cheap INEXPENSIVE off brand sunscreens such as target and walgreens and other SUNSCREEN brands. I bought 5 sunscreens and tested them all using UV color changing beads in the park. The uv color changing beads react to sunlight and all uv light. The sunscreen was smeared on the bags and then opened up to the sunlight. The bags with the UV beads in it that didn't change colors too much showed that the sunscreen was working well! The darker the beads got from the suns UV rays the worse the sunscreen was!

Oh nice vid man i am such a big fan you work so hard bro you spend alot of your time just entertaining us I subbed keep up the vids your the best
Thx I really appreciate that! 👊
Np bro dont let your gaurd down and never give up keep up :)
the actual experiment starts at 4:46
you should have used a measuring spoon to ensure the same amount used on each.. but otherwise, great video
He wiped most of it off! Can't wipe evenly. Should've put less and left it. 😜
Great street smart science to this video. If there is a part 2, it would be nice to include Neutrogena. If you have slow motion that would be helpful since the color change was really quick.
Great vid man keep it up
Where did you get the beads from?
this came in my chemistry exam and we had to make an investigation on it like yours
This was very interesting! Nice video!!!!!!!
Nice vids you are a smart person I can’t even believe how you come up with smart ideas keep on doing what your doing < 3 😀
I like how he dose not do clickbait and he proves it.
Cool!
Very nice video liked it 👍🙂❤
How come u not at 1 mil yet ???
Next Science experiment I want you make 🌪 soda bottle
I think you should have poured the lotion in each bag and shook them thoroughly to test them
Cool video but I use like 50 plus of the banana boat and the Hawaiian tropic and they work great i am outside all day and 2nd of all the lotion sucks compared to spray i find but like i saud nice vedio 😎
how did he know i went to the beach today. I guess Science!
This experiment is not totally fair though, because the distribution of those colored beads was not equal in every bag - which lead you to say that one bag looked more pastel than the other two :D
Also, since the time it takes for those beads to get colored is soo little, it is crucial that you remove the towel at the same time for every bag and not put it back onto e.g. two out of four bags. That’s why I’d like to tag this video as “science adjacent” 😂
Yes but they were out in the sun long enough so that each bag had enough time to get as colored as they were going to get...the bags don’t absorb the sunscreen and wear off like it would on a persons skin...the purpose of the towel covering the beads at first is to make sure the beads are white before the experiment starts.
Yeah, there were a lot of variables that weren't fully taken into account. Were the amounts of sunscreen precisely the same? Was the layer the same thickness? Was the sunscreen wiped away by the towel? I am skeptical.
@@Erudessa22 Skeptical is good and what science is all about is changing the parameters to see what elements cause changes. Then you can write the paper...or do the video.
I'm doing this for my SRP project for year 10! I'm doing it slightly different tho, and using a measuring cup to put the same amount of sunscreen so it's more accurate. But this vid was very helpful!
Banana boat
#Lightning ⚡️🌩
I think Hawaiian tropic will work best
Try it in the mirror Lightning 🌩

Hey try with aluminium foil
I think banana boat
Yer

Actually the conclusions of your experiment are entirely wrong. These “UV-sensitive” beads are not changing color because of exposure to UV waves.
The intensity of the color varies inversely with temperature-less of the colored form of the photochromic dye in the beads is formed at higher temperatures.
Then what’s causing the change…indoor heat doesn’t change its color…a UV flashlight does which proves the UV reactant catalyst
