Bro don't touch the water, who knows what new virus gets cooked up in your ecosystems

I wonder if it would be interesting to make some jar replicates where you supplement some of them with calcium or iron or other limited nutrients.

The forbidden green tea.

Would be interesting to examine how eyed e evolved in sucha habitat across various heterotrophs

9:26 1/80,000th of a football field. Got it! Thanks!

What I also found interesting is that "Egel" in Dutch means Hedgehog, while "Egel" in German means Leech, while Hedgehog means "Igel". I looked it up, and it seems that Egel and Igel are related to snake or worm, and an "Igel" would be a snake- or worm-eater. Language is interesting.

KZfaq hid your stuff from me, now I habe 8 month of content to catch up on... Wait a minute this is awsome

We shall meet in the place where there is no darkness

Congrats on your presentation. You manage to hit the right note every time.

pee?

Do it with darkness

I just wonder, what if you film them somehow without having to put them in darkness? Nightvision camera maybe? Although those are quite pricey... I just think that some of the organisms used to darkness may change their behaviour or even get sick when brought to light.

"8 äugiger blutegel" translatres to "8 eyed leech" not hedgehog (igel) egel = leech, igel = hedgehog.

Now what if you shut the lights off for 4 years?

If you made the jar big enough and made it rotate so only one side gets light at a time you would have the earth.

I'd like to see something about the development of a biofilm on the solid surfaces in the body of water. As an aquarium keeper, I'm aware that an assortment of microorganisms live on the submerged surfaces and little by little create a matrix that feels to the touch like slime, but it is actually a complex ecosystem. It takes many months to develop to maturity, so I suspect that it actually develops through a succession of different species. It would be interesting to observe it's development.

1/18000th of a football field my favourite measurements

I watched the entire thing and don't remember what happened to the starfish.

Let us know if they attain sentience.

Now constant light for 40 years

I don't agree with them actually not having a night and day. Because it was shining, a light doesn't mean they never had a day or night. What they saw in the daytime was dramatically different from what they see at night time either though they were having light shine inward but what they saw outside in the daytime and night time was completely different 🤓

What happened to the starfish????

What a strange part of the internet I’ve found

So you changed what is known animals need and in spite of direct proof that some of them were suffering you kept going? You could argue this was scientific but this happening outside a lab makes me worry about videos 50 years from now titled "I threw a litter of dogs into an unlit basement for 4 years and what happened next will amaze you!!!"

I like these vids!

Amazing…although it does make me not want to go swimming, or even paddling, in the sea. Definitely no dunking of heads! I wear contacts so I am always wary of that though. What happened with the sea star?

Evolution outside the jars has taken place in an environment without constant artificial lighting since the dawn of time, so who's to say anything *needs* a night cycle.

The fact that 1/1800th of a football field is an easier measurement to find from most Americans is kind of sad

Where do you live? Looks like nice area

9:20 1/18000 of a football feild lol😂

Pretty cool man i remember doing this in school and it died with in a month or so 😂 i would like to try again with my children now that im older

Now restart the experiment but with a control jar with no artificial light. And maybe another jar with light from a different source other than LEDs.

Drink it

Pro tip: dont drink the water. Youll thank me later

You really deserve recognition for this 1.5year long project

now leave it outside for millions of years and let them evolve into humans

hey thanks man, i was getting thirsty

👍

Tell a random kid its a chug jug

Put a human there and he'd go insane!(called isolation chamber)

Hey I don’t know anything about those worms or animals but they might have evolved in those 4 years. Usually insects live shorter lives and thus reproduce faster

I'm pretty sure I saw Donald Trump float by at 3.5 years. For your French audience, 1/2 centimetre is 1/200th of one ten millionth of an incorrect estimate of the distance from the equator to the north pole. I hope that helps.

This makes me think if a day-night cycle is really necessary for life to develop on a planet. Well, heat distribution would be a HUGE problem, but I think planets would find a way of achieving it without rotation. We know so little about universe anyway.

The "dancing" worm probably got insane due to no sleep over month

Eight eyed blood hedgehog is badass name for a critter

I think 0.5 cm is a little less than a quarter of an inch?

Watching this with insomnia is appropriate.

you forgot to mention what happened to the starfish....... im assuming it died......

Centimeters into fractions of football fields? What? Lol.. how bout convert into inches. Js

Love the leeches name is a sonic oc name
