Why Are 96,000,000 Black Balls on This Reservoir?

čas přidán 10. 05. 2019
I took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they're there. The first time I heard about shade balls the claim was they reduce evaporation. But it turns out this isn't the reason they were introduced.
Huge thanks to LADWP for arranging this special tour for me. Next time let's put the GoPro on the submersible!
The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the main reason they are on the reservoir is to block sunlight from entering the water and triggering a chemical reaction that turns harmless bromide into carcinogenic bromate. This effect occurs with prolonged exposure to bromate so regulators insist that levels be kept below 10 microgram per liter on average over a 12 month period.

This is an educational video about the science of water quality.


  • I'm sure Metallica had black balls floating on their audience a few years ago. Just sayin'.

  • In a few years they will need to be cleaned from the microbes that have been adhered to and created colonies

  • And more plastic.

  • If the sunlight not enter into this water then growing microflora under the water which is beneficial for any living being and which could be no more in the water, thus leads a cause for lethal drinking water, No life under water means no life in the water. Who going to drink this have no normal life on this earth.. can any one thing about which food is non degradable, you and me are all made up of degradable Biomaterials, The truth is like this then Where is this food grade quality coming from the Hell.. O what a Stupidity, using Science to make videos to Fool common Human Civilians.. Bad Bad Bad this is very very Bad thoughtful idea for humankind..

  • Any thing can reacts with sunlight and Black colour is more likely to observe sunlight in means of Heat and also the possibility is more reaction will Happen between this water and Dissolved Chemicals of the Balls in People Drinking water thus leads to Cancer of Human lungs kidney even Blood and brain.. so people Please be away from this Water.. Go for Harvesting Techniques of Rain water to increase under ground Land Water which is very pure and healthy drinking water than this type of treated Brominated, Chlorinated abnormal water.

  • Finally watched it! Always in my playlist! Wasted my time as usual

  • Because an engineer named Brooke worked there.....

  • Finally watched part of this and CS-tv stopped spamming me with it. I guess these saved the Earth.


  • I bet these plastic balls are more toxic....

  • Again, the Luciferians screwing around with God's Natural Order of Nature. KILL these Demonic people because They intend to Kill us as part of their UN Agenda 21-30 Depopulation Program. Look it up, it's ALL Right there to be read in their written Agenda for Humanity. Any of you who don't bother to research the facts of this are just Stupid and Lazy and shouldn't have the Right to say a damn thing that refutes Any of it because your Stupidity Disqualifies you from doing so.

  • That girl is such a stoner

  • Great more "recyclable" plastic..

  • i didn't bother watching this annoying video. i paused it before i typed this and went on to next page after typing and pressing send. i've seen this retarded video weeks ago before i realized it was a retarded video. couldn't be bothered to torture myself again. and this video gives dangerous ideas to potential kids out there. i should report this video for negligent behavior.

  • Why am I watching this? How did I get here? Lol

  • Was the engine on the boat fuel injected or carbarated, 😂😂

  • It was proven that they are useless and don't do anything

    • Fake news

  • As long as we keep using Petro they have to come up with excuses to sell plastics.. thank you opeck for another "diversion solution" to continue to make money poisoning us and our world.. what's next? Poly our atmosphere because of pollution! Sell sell sell. $$$$

  • The Kardashian Reservoir

  • Because some asholes felt like polluting the earth with 96000000 balls for a stunt no one will care about after 5 seconds of watching this. You're a waist of space on this beautiful planet. You're a disease.

  • These will blocked out sunlight from getting into the water and these will kill all the phytoplanktons which produce oxygen for the aquatic living organisms. They died and causes anaerobic bacteria (mostly toxic) to grow exponentially. Poor idea. So residents nearby will not contract cancer due to the carcinogens caused by the chemical reaction but will get sicken in other ways.

  • Is this Shadesmar?

  • This almost tops the 96 million blue balls I had in high school

  • I've never seen an entire reservoir get blackballed

  • they should do this in lake mead in nevada...might help the evaporation level and help the lake start to rise again!

  • To keep the sun off the water. There, that took one second to know why. Your video is 12 minutes.

    • @Trap nah, I just didn't care to watch it all. CS-tv kept shoving this down my throat.

    • @Anzu love He literally explains it in the video, are you dense?

    • But anything black gathers more heat than anything... How does that keep the water from evaporating?

  • From may till July. This video still popped up on my recommendation. Hope that I'm done here...

  • The problem of the appearance of carcinogenic bromate in water is deliberately exaggerated. This process in reality is insignificant. This story is designed to camouflage the real reason for the huge amount of chopped plastic in the water. (The truth is somewhere else...) Thousands of tonnes of plastic in water in the form of a 4 inch ball is suitable for the fact that this way creates the maximum surface of the plastic that is in contact with water. Water can decompose everything, just give it enough time. The balls are in a black color in order to accelerate the degradation process of polyethylene on the heat of the sun. Polyethylene (HDPE) contains Desphenol-A (PPA). This chemical mimics Estrogen in the human body. Absorption is possible even through the skin. Further explanations are not needed. This is a great experiment. (In vivo)... LADWP has nothing to do with this. The plan came probably from a higher level... (The Administration, the Government, the gay lobby... who knows!!). It can easily happen that this method is adopted by other US cities. In that case, the only solution for US men will be to find some natural sources of clean water. It's a little complicated mission in dry California, but everything is possible. (Ps- Plastic bottle water is also contaminated. ) "I wear a plastic suit, and plastic is my food, maybe I'm plastic too" ... ;) .. Sad but true.^* Good luck to all... *(R.I.P. for a dead the bird in engine).

  • 1:28 there would be balls bouncing on the freeways

  • Lol

  • @ 5:51 a bird loses its life to a propeller! lol

  • But its plastic,,plastic breaks down!causes cancer

  • i don"t understand!! why are you having a bout in the Reservoir! drinking water is polluted with oil gas from the boat!!so silly eat thing ever!!!

  • Marty Adams gives great explanations for all this, seems like a good guy to lead LADWP. He also looks like Christian Bale playing Dick Cheney in Vice.

  • Refreshing.a positive story on having balls

  • Let's do some math... 96,000,000 x.33 cents each = $31,680,000. One of your questions should be who got the contract for those balls.

  • What can you make with a recycled shade ball?

    • You Ought To Be Ashamed Of The Lack Of Input In Your Message. Whatever Course You Took, I advise You To Try To Get Your Money Back! HA HA HA HAHA HA HA HA!

  • What’s in the water that’s inside the balls? How bad would they smell if you cut one open after a year in the sun?

  • #ClimateChangeScam!

  • Why a gay voice? Why do they always have to fag up every show with a homo host?! #GayMafia

    • He's married to a woman and has a child. I think you're projecting your own faggotry on to him. Go back to sucking dick now, homo.

  • I half expected to see Sheldon pop out of the balls yelling " bazinga"

    • When were you released from the mental ward?

  • What a technocratic, carcinogenic solution to a minor problem. Am I the only person who thinks this is a total nightmare?

    • The solution isn't carcinogenic. Also, the problem they're solving is literally carcinogens, so is this a minor issue or not?

  • Look like hell.

  • Anti evaopration...didnt need 12 mins to explain...ya dumb asses

  • I hope this is recycled plastic!!

  • I call this weed NASA my nigga lol

  • Animals can't survive with light. Unless that just where y'all hold them

    • LOOK! LOOK! There's Daniel Hook Diligently Reading A Big Old Book. Oh Daniel Daniel Have You Found, That Book You're Reading Is Up Side Down? HA HA HA HA HA HA!
