if you put a drop of food coloring what happens to the bacteria?

they teach us centimeters in school...

Where in the Netherands have you managed to find an actually relaxing bench?

Hard boiled eggs are a hit in Arizona

There's a squad of corvids who greet me with a particular sequence of caws wherever I go within an approximately 2km radius of my home. I believe they are crows, but they might be ravens; I don't know the difference. I didn't intentionally set out to befriend them, and to be honest, I'm not sure what it is about me that originally attracted their attention, but there is something reassuring about being recognized in an urban area where people are somewhat reluctant and inattentive to strangers. My well-meaning gesture of leaving small food items met with mixed results until a friend of mine told me about unsalted peanuts. At first, I didn't understand because for some reason in my country people use the words "shelled" and "unshelled" to mean the same thing, and I thought the crows would appreciate not having to peel the peanuts. But in fact the opposite seems to be true, at least with these particular crows. They responded very enthusiastically to small gifts of peanuts still in the shell-they seem to enjoy "unwrapping" them, as if the shell were keeping the nuts inside fresh, the way we do with candy wrappers and the like.

I wonder if it would be different if it were an open environment (no top). It would be cool to measure the CO2 & O2 levels to see if these are correlated with a decrease in diversity. Also water PH.

Feeding the crows is good, doing it at a specific time works far better however.

When I was in junior school in the early 70's we did a similar thing with seawater & assorted sea life in a big fish tank .. after a month it was a cloudy green septic mess & stunk the glassroom out 🤮

I don't understand why you wouldnt at the very minimum aerate the jar no filter etc just some bubbles for oxygen

He is going to become like the pigeon lady from home alone, but with crows.

My car 🐈 ❤️s this video

Pt3????

Unsalted peanuts 🥜 in the shell..they go crazy

When I start a fish tank I do stuff like this. Go to the wild and grab some soil, rocks and plants. Especially duck weed. Helps the biodiversity which helps the niche needs all get filled.

Makes me want to do a salt aquarium and stock it with only critters I find locally while scuba diving. The little crab was the coolest. RIP little crab.

Death match. Jar map. Wonderfully interesting content.

You're the science teacher i always wished i had

You are potentially the last living human on earth.

upon hearing the line: "I left you guys in the dark", I was forced ,by sheer charm, to like the video.

What microscope equipment do you use? I'm interested in trying my own jars

Leave it to a dutchman to see the ocean and have an instinctual need to wall it off.

Minification can also be an evolutionary effect. In this environment smaller individuals may have a higher chance to survive.

The "egel" in "bloedegel" does not mean "hedgehog". The Dutch word "egel" can be a hedgehog, but also a synonym for "bloedzuiger", which is a leech. In German the difference is clearer: "Igel" for hedgehog and "Egel" for leech.

Yes please

7:25: Feasting on ancient growth algae! Kind of like if we were to find some grain from Roman times, grind it up into flour, make bread from it and realize that bread was fabulous!

Only humans find it of interest and worth sustained effort and purpose to build something more than opportunistic or parasitic relationships with other species. That is quite interesting. What with me being a human, and all.

Subbed. What a fine gentleman 😂

I am pro crow

Is it assumed that most or all the early microbe action was from the dried residue, or could some have come in on the air? They were uncovered, I believe.

Such a thoroughly enjoyable series. Thank you!

I have three pet crows corky porky and snorky they will be getting strawberries for their Christmas. 😅

is this why there is no new videos?

Very good dry humor. Love it

Thank you for your wonderful video. I have begun to keep isopods myself.

I hope the crows are becoming friends :)

That worm with tentacles was pretty cool.

I can't wait for part 3 :)

We need a corvid update! I hope you are doing well

Quite the world in rain A rainworld if you will

Squirrels best step off!

I had a 200gallon salt water fish tank, on a small corner had a thriving colony of tiny shrimp and nother areas had a colony of tiny clams.

A very good and educational project. Looks like fun also. 😁 👍 💯

PITY ABOUT THE BLOODY AWFUL MUSIC.

THEY ARE NOT CROWS! Ravens!

I use a pet cam on my balcony - the balcony is covered and it wont be rained on so no need for a trail cam. I've got Eufy and Tapo 🙂

until now..... because hes dead now XD

Six years damm

Nice!

Youre surprises are the most ajarring
