Six Years Ago I Put Saltwater in a Jar, This Happened | Natural Saltwater Ecosphere 6 Year Update 

What a refined gentleman and his ecosystem

I have a sealed 23 year old jar of water and rocks from the Great Lakes. There's still algae in there! Your channel is fun, thanks for your work

It’s so nice to find someone else who finds meiofauna a interesting as I do-and can put names to them. And has a good way to film them! Thank you to all the patreons!

this feels like a classic youtube video, and i cant stress enough how happy that makes me

> dapper suit > funky groove > eulogy for crab > meticulously explains > leaves ultimate sigma

I can't believe it's been six years since this jar was setup, I still remember when it was built, and remember the sadness I felt when the crab died.

You're looking mighty dapper! RIP crabby, you are missed. 🦀

These videos always give me a uncomfortable reminder of my mortality and the passage of time. Thank you for updating us though its always nice to check in.

Thank you for this humorous and intellectual course into life in jars? in the most gentlemanly way possible, truly a masterclass in your field.

To this day, this is still one of the most entertaining RU-vid channels I’ve ever found. AntsCanada is also very good! Thank you for your very interesting and entertaining work. 😊

Well done young man, still applauding your dapper attire! Sir David Attenborough would be proud of your efforts.

this is a historic occasion

My favorite part of these videos is when we… you know… *take a bit of a closer look*

I love your ability to roll those Latin names so easily off your tongue. You have my admiration.

I just watched that first video last night. What a perfect coincidence.

I love your channel. Even in a jar after six years, there's something new to explore. I'm amazed at how clear the water is.

American anglers and fish farmers often add salt to freshwater for creating longevity and vigor in freshwater fish. It helps with the slime coat and other issues. Since your saltwater ecosystem is your most successful experiment, have you considered adding salt to a new freshwater ecosystem (with an exact duplicate with no salt as a control) to see if there is a noticeable change in vigor and longevity. I'm thinking of how, in the distant future, terraforming planets will be a thing as we establish colonies out in the stars. Once we figure out faster, better modes of transport, we'll need ways to preserve and prepare species for transport. Salt to freshwater ecosystems may be a gateway into this type of research...a way for you to inspire budding future scientists that might one day be working in this fairly new field of study.

Trying a North Sea tank might be a fun project. You could put crabs and some other larger creatures in it. Anyway, it's good to see this system is still around. I was wondering about it.

Can't say how much I enjoy this channel, will be watching this video as soon as I get home from work

I have both graduated college and will be going for my PhD in the time this jar has been going...What an experiment!

the "having the time of my life" on the back of that shirt seals that image, really brings it to the next level.

This channel really gives me a chance to gain an appreciation for all forms of life - including bacteria and microfauna - that I didn't before. Thank you!

6 years and there is still life, what a legendary ecosphere

Years and years ago I commented on a video that your channel was going to blow up someday. Look where we are now

From USA, Love it, love it, LOVE IT !! 6 years !! Can you believe it !!

I agree with Future You. He makes a good point!

Nothing excites me more than a new Life I Jars video. I’ve always been very interested in science and I can say without a shadow of doubt that this is my absolute favorite science oriented channel I have ever found. I’ve been watching for more years that in can remember, and I’m very happy that you are still providing us with such interesting content. Keep up the amazing work!

its always a treat when life in jars uploads!

6:52 “Eaten by everything that wanted to eat it.” Possibly my favorite line ever.

Hows the crow project going? Im excited to hear any updates on your crow befriending project as its something i always wanted to try my self.

Yes! a new post!!!

This is honestly one of the coolest videos I've EVER watched on YT, and I've had a channel here for 13 years! I don't understand how everything grew without circulating oxygen unless the algae created oxygen for the tiny inhabitants. Subbed and clicked the like! Much respect, beary

MY FAVORITE SERIES. The 2 year one is what got me to subscribe :)

Wow it has been 6 years since I started watching already

A round of applause for sharing your project. 👏🏻👏🏻👏🏻👏🏻

I was just talking about this exact ecosystem with my dad over the weekend. Super cool to get an update. Great video as always!

This guy might be the coolest person on the planet. His honest curiosity and dapper presentation make for one heck of an interesting video?!

Love your videos! Good to see you again! ❤❤❤

Another interesting vid! So happy when you post!

i really admire your patience with observation and documentation of these ecospheres. fascinating stuff. (missed ur channel!!)

Great video o love it when you go back and update on various eco systems you have set up for long term

This video is so relaxing. Always a good day when bro posts not only that but bro be stylin.

I miss the lil Young Shell. I think this was around the time I found your channel. Core memory unlocked 🥺

I was a subscriber way back when I was all about ecospheres and foo the flowerhorn. Happy to be brought back! this is such a cool long term project.

Nice jar, please continue showing us you ecosystems ♥️

RIP crab

At least you make these experiments with good information to give us! It's very interesting how there is always something alive in harsh environments!

i just rewatched the salt water episodes like 2 nights ago

Im so happy i found this channel in the middle of the night

How interesting! I am amazed you have a stable ecosystem in that jar.

Oh man I misses your vids, happy for a new upload

9:38 Potion Seller vibes.

LIJ IS THE ONLY ECOSYSTEM CHANNEL I WILL WATCH. EVER.

Thanks for making Life in Jars fun

I LOVE THIS NEW FORMAT

Another fascinating video! I don't know what your plans are, but whatever they may be, you have an amazing future ahead of you.

Neat to see a different biome covered this time around. Even if some of the bigger things didn't make it, the little ones are pulling through.

I love this! As a kid I got amazed at a gutter that didn't drain well,and it contained green slime over mud,and then it had a white worm that stretched it's snout(?I think,or whatever)out long to it's destination.This was in an urban area that had so little of the wild things that I wanted to see.I absolutely love little ecosystems that can be studied.You hit the nail on the head as far as I am concerned! It would be so cool to also figure out what the very tiny creatures are.I am so glad you posted this,because I was so sad that the ocean water seemed hopelessly dead.

Looking smooth my friend

I remember this series during pandemic time, poor little crabby 🥹

Your experiment just proved something important. I hope to see how your experiment continues to evolve.

This reminds me of my tiny ecosystem that is brackish water with my tiny shrimp, opae ula . They are 6 years old now, and thriving! The only difference is that my lid isn’t airtight,also I have to add water every 6-8 months to keep up with what dissolves. But I went from 5 shrimp to around 60-80 maybe more?! I absolutely love watching them live and thrive, have an entire new generation and how the colors change with each generation.

I Love your Video! I had never expected that i could be so fascinated by Something so small and curious. And your Style is extraordinary and i Love it 😊 Time to Look the Rest of your Vids 😊

This was soooo cool to watch. I’ve only thought of small microbes as evil little things that need to be killed (because I work in medical and we sanitize everything), but seeing these live so long and so essential to the life in that system has given me a different perspective on microorganisms. thank you for what you do!

Sure glad that into wasn't awkward in any way. Went off without a hitch. Total success.

When I was taking reference photos of fresh water microbes, my colleague 3D printed a device that holds a phone steady while keeping it at a good focal length relative to the microscope-super useful! Maybe someone clever can help you out by linking a design that could work for your setup. Love your channel!

your the goat🔥never stop these videos

Looking rather dapper there, sir. This bloke is going to be a professor one day, one that his students will think is a riot.

the thing at 13:30 is also a copepod, its probably the larva of the harpacticoid copepods

i love your little touches of humor

Simply amazing great video and documentation

Thank you so much for making all these videos, all of them fascinating 🔎👀

Liked your style of presentation. Great video.

I love what you have made!! Your interest is like mine, wonderful job!

Thanks for sharing

I enjoyed this great video with my morning coffee. ❤

Looks like you're ready for a pleasant afternoon good sir. Top of the mourning to you!

ooooo happy to see an update on this one! Its awesome how stable its managed to stay, though I wonder what it would look like now if the heat wave hadn't happened

Cool video, I truly enjoyed it.

I instantly knew you were Dutch with that accent. Toffe vlogs jonge, blijf ze maken.

Not only humorous but quite interesting!

When a new Life in Jars drops, you know its gonna be a good day. :D

That final contribution was very insightful. It was evident that the gentleman has taken much more than just a little bit of a closer look. The closest look there is, dare I say

I did this once as a kid, and I was able to get a bunch of stuff from Lake Michigan into a one gallon glass jug, and it remained alive for a few years, until my mother uncorked it and tossed it as rotten.

Now that is a sharp dressed man! I clicked on this vid just out of curiosity for the suit & then the jar ☺️

I’ve been wanting to create some resurrection jars❤️Love how the crab buries himself

Love You video that was a proper experiment

You should do an enormous closed ecosystem, like a custom 3ft aquarium, made airtight. That should, in theory, be able to sustain larger organisms like a crab for far longer.

I unironically love your style.

I would have given up after all the algae died. I'm glad you kelp going👍

Wow. Amazing

you should try a sort of magnetic movement system in the jar to keep it sealed while still having water movement

life in jars best yt channel

Your voice is so relaxing, i love it 😄

Love the duds keep up the awesome science!

Very interesting video, it is really cool to see the evolution of an ecosystem up close.. even if it looks like there isn't, there is so much Life in those Jars :D

I´d really love to see a comparsion of two closed ecosystems, one taken from the north sea and one from the baltic sea!

He looks smart in his suit!I live in H'Pool(near the power station)I'm now tempted to go fill a jar with our seawater and I might be able to grow a superhero-I'm not being sarcastic, honestly😊

ur videos are amazing man

I didnt expect bro to look so fancy lol
