- Let's do a fun science experiment! We're going to learn how to find Water Bears. Join me to learn about these awesome microscopic creatures!
Tardigrades, also known as Water Bears, are adorable microscopic animals. They look like caterpillars and walk like bears. There are over 1000 species and they can be found in almost any habitat. That's a lot of Tardigrades!
Water Bears are also known to be pretty tough. Surviving extreme heat, pressure, and radiation is a walk in the park for them. So they should be able to handle New York right? Well let’s find out!

3:54 ...Rolls a water bear spliff.
This geeeewn
I'm gunna be scared to touch anything anymore I don't wanna hurt the cute lil waterbears aha
+Swag King lol. Don't worry those tardigrades are pretty tough =)
Don't worry you cant
+Mario Mario they litteraly can survive the sun
The sun burns at 5,777k. Tardigrades can withstand 420k. Not sure where you got that from!
Sorry people keep giving me wrong info
So they can survive the vacuum of space, but not tap water?
+Mike Cassell Fluoride ;-;
+Mike Cassell Actually i think they care that it can kill them and they dry themselvs up and not take that water so they use the other water in order for the water bear to re-hydrate but they dont die for being expose to tap water :v
+Mike Cassell Because they are in cryptobiose when they survive the vacuum of space. When you put water, they leave the cryptobiose and if you put tap water inside of the water they have in their habitats, I guess you have a difference in osmolarity (basicallly, the quantitiy of particles contain in the water). Depending on the difference, the water diffuse and will leave the cells of the water bear, or go inside (its cells explose) to reach an equilibrium.
Remember that they are not too eveolved animals. Your kidneys are in charge of regulating the osmolarity. Without your kidney, I guess you'd be dead. :p
LOL I'm so disappointed here I'm thinking that water bears are indestructible and
can survive near Absolute Zero, but tap water kills them!! xD
*****
Hey could you imagine if there was a giant Water Bear? like the size of a car? would it be indestructible? xD lol
Wow dude, that was a really high quality video! Keep up the good work!
Awesome! Love the music, and love that you showed it might take more than one try to find something. Yay for tardigrades!
Water Bears don't give 3 micro-poops.
Micro poops? LOL
You mean to tell me that these things can survive in freezing temperatures, the bottom of the ocean, and the vacuum of space, but tap water will kill it instantly?
They can also survive extreme radiation and toxic waste but not tap water xD
He didn't say that, he said other microorganisms would die, which I'm guessing water bears might use for food.
TAP WATER KILLS THEM, THATS THE SECRET
Gregory Daedalus LMFAOO I KNOW RIGHT!??? HOW ABOUT THE HUMAN STOMACH ACIDS!????
They in Flint
Sharing with my home schooled niece as an outside adventure...thanks so much for putting this together!
Tardigrades were one of my favorite animals as a child, the fact that they can live almost anywhere
Me: * considering buying a microscope just for the reason to have a waterbear as a pet *
same-
@@cass137. they're so cute 🤗
can you keep water bears say in a betta tanks? without betta or anyfish. but would they stay alive if you add moss and water?
+rmpbklyn I'm pretty sure that would work. Only way way to find out....
Thank you SO much for this fun video. My kids and I have been looking for water bears for a couple weeks and no luck. We'll keep trying but your advice about not putting them in tap water was super helpful because I hadn't thought of that. Thank you!
We're still looking for them and have been for weeks. I feel like we've tried everything but all we've found are a ton of nematodes, rotifers, and parameciums. No tardigrades :( Any extra advice?
3:37 I thought he was about to drop bars 🤣🤣
I giggled at that "water burr" song at the end. You are nine kinds of adorable! And tardigrades are my FAVORITE animal!
Amelia Bee Glad to make you laugh =) Water Burrs are awesome!
Awesome educational video. Ordered x12- x1200 microscope for me and my nephew to play around with and best believe we are going tardigrade searching in all the moss. Thank you thank you! Now we know where to look.
That was an awesome video. I love the enthusiasm.
I live in the desert and tardigrades are thin on the ground (or sand, in this case.) Therefore, I sent away for some for my terrarium. They seem happy here because every sample I take out has at least one and sometimes I catch them partying by the dozen. They are just so damn cute and I'm glad they are benign and hard to kill. We have a lot to learn from the little guys about the tun state.
You crack me up man, I'm glad I happened on this video, new sub!
I have seen them all the time but just didn't know what they were until now. such an amazing animal
Lmao what a nerd
.....I love him
Are the tardigrades likely to swim out into the water you use to rehydrate the moss or are they and rotifers, nematoads, and the sort going to stay around the moss? I need to be able to count them for a project i'm doing.
+TheRedKnight I can't say because we have had some water bears vanish in past. Recently I did this with high schoolers and they saw one water bear walk off out the petri dish and onto the stage of the microscope. Stay inside the moss? Water Bear Don't Care!
Hi! I have a jiusion USB digital microscope and was wondering if you had any tips on helping me find some water bears?!
Great video! I have known about water bears in the past but never where they actually lived. I recently visited a smoky mountain trail (tons of moss, lichen, and diverse environments there) and I am frustrated I didn't take any samples. AHH
I'm gonna follow your advices, next week I have laboratory's class, and I have to bring some samples.
Hey, just want to know is their any way to grow water bears once you spot one. How do people grow or maintain them in labs for research? any idea?
+Abhinav Yadav Not 100% sure. After viewing them, I let them back into the wild. Here's a wikihow that may help - www.wikihow.com/Find-and-Care-for-a-Pet-Tardigrade-(-Water-Bear-)
Im diggin ye hiip hop science, brah, good crack keep it up!
Hello there! Can you tell me how much magnification was used in the microscope to look at the tardigrades?
+Chandan Bhowal Hey, you should have no problem spotting water bears at 20x-30x.
Thank You very much! Totally doing this!
I don't know who you are but you had me at hello science friends, subscribed
Is there a way to condense the sample? Or, is there a safe way to evaporate some of the unnecessary water in the sample to make them easier to find?
man I love this video. Tardigrades are my favourite little beasts. them and slime molds.
how do you culture water bears, i would like to keep them as pets.
So water bears (tardigrades) can survive the vacuum of space, withstand radiation, enormous heat and cold, hibernate for as long as they want, but die if exposed to tap water?
What the hell tardigrades?
Also why does tap water kill them?
Povilas Račkauskas Tap water kills them because M. Night Shyamalan :)
Povilas Račkauskas Great question! Water Bears are tough, but they are not invincible. Of the Tardigrades in space, only 68% of them survived (which is still pretty darn impressive). Their extreme survival is tied to their ability to enter cryptobiosis. When the environment is unfavorable, they can slow down their life processes to .01%. When things are better they come back to full life.There are 5 types of cryptobiosis and Tardigrades are able to enter all of them. There's....Anhydrobiosis - Response to lack of waterAnoxybiosis - Response to lack of oxygenCryiobiosis - Response to decreased temperatureOsmobisos - Response to increase solute in the environmentChemobiosis - Response to toxins in the environmentIt appears that Water Bears are pretty vulnerable when they aren't in Cryptobiosis.Now the Tap Water. Tap Water may have chlorine. Chlorine is used to kill bacteria and other microbes. Now, I have not verified this for myself, but I hypothesize that if there are water bears moving about (non-crypto) the chlorine may affect them. They may die or they may enter Chemobiosis. If they are already in crypto, they may have trouble reanimating. Thanks for asking.It's a really great question and because of that, I plan to put tap water to the test. I'll share the results I find. It will take some time. Also Cryptobiosis is so cool, I'll do a SCI CODE on it and go into more detail.
Coma Niddy Wow thanks, that's really cool !
NTeamEN I don't get it (M. Night who...)
So I guess tap water is like a water bear's kryptonite.
uhh yes, yes it would. tap water is treated to kill things just like waterbears. people dont want to drink random organisms all the time, thats how you get very sick. this should be common sense...@Truth Troll
this looks like so much fun!
What was the magnification use to spot the tardigrades? Could I increase my chances by using a centrifuge?
Gonna try this thanks 🙏
Awesome video, helped me out a lot
This Spring I climbed an old growth Redwood tree (800-1000 yrs old) and collected some lichen. I can't wait to rehydrate and see if I can find Water Bears.
Hey! Were you able to find anything?
shollins74 .....You climbed a redwood to collect water bears? I cannot express how amazingly cool that is
They are so cute!!
This is my favourite type of animal I love them sooooooo much!! I know it sounds weird but it is true
Can you tell me about the ole H20? I can’t figure out what is it.
That was great. Thank you.
Mona Conway You're welcome! If you go on a Water Bear search, be sure to share your adventure!
Anyone know the name of the microscope that's displayed w the mac?
did that end card start rapping about water bears? lol
+MrThisucks that would be my song "water bear don't care" ruclips.net/video/z9Mw44u0UBw/видео.html
+Kathleen Bragg awesome! Let me know what you find!
Any video with water bears should have cute adorable stock music with it.
Another great vid on my fave critter, Mr. Niddy, keep 'em coming! Some day, I hope to be able to get a microscope and snag some bears of my own for pets.
would it be possible / likely to see water bears on just a wet prep slide with a coverslip? I don't have access to scopes that can look at pooled samples like that... =/
+Janine Murdock yes. It just may take longer to find find them since you would be looking at a smaller sample.
+Coma Niddy excellent, thanks =)
Cool stuff!
Thanks for sharing and I have subscribed
what magnification can you typically find them at
Awesome video 😊
Love this video
There is a water bear zoo at the Meteorite Store in Pottsville, Pa
Tardigrade: *exposed to lava*. Here we go again. Humans messing around with me.
I’m gonna be looking for a water bear this December!
How much magnification do you need to see them?
How do I know if I am paying enough for a microscope that can see things this small? I had one when I was a child but it could make lent and hair look big, that was about it and that one was 200 .usd. I just want to know if this is now a practical thing outside of having commercial equipment and what magnification I need. Thanks
40x magnification is the minimum magnification you need to see water bears. That can be done with inexpensive microscopes!
thanks!
THANK YOU!!! My kids and I were curious after reading about some new research studying the "DSup" molecule found in tardigrades. Being moist as Seattle is, we're hoping to find 'em right outside our door - from your video, it looks like that may indeed be the case. :)
Seattle should be no problem. I live in Portland now and it's so much easier to find Tardigrades. The moss is so bushy sometimes you don't even need a knife or tweezers. You can just pull it off, soak it, squeeze out the water and sometimes in a few minutes you've got a bear!
@@mike.likes.science At what strength magnification did you search?
Weird question, if they get in your body, do they cause harm or just pass on through?
Fascinating
My mom works in the science lab at school and she let me do this and I found two they are so cool to watch wiggle around lol
Great, you found it. They didn't show it. Instead we zoomed in on your face. Nice one.
Thanks Mike
Great video I’m trying this now.
Good luck and have fun!
@@mike.likes.science I am so far! Using the Brock magiscope, so far some cool closeups of rotifers, protists, springtails... no tardigrades yet!
Subbed. Because I also like science!
THX SO MUCH WITHOUT YOUR HELP I WOULDNT HAVE FOUND IT SO... I WILL SUBSCRIBE AND LIKE
I am going to find one soon, you care for it by giving it water right?
I guess the vid did as promised (showed how to find em) but it would've been nice to see some footage of the creature in action at the end
Did you make a video on searching for that one creature? The one that's even harder to find than the water bear? I don't remember what it was called. I think the Latin name was SomeoneStillWillingToSleepWithYouAfterWatchingThis.
That was great thanks :)
how much time took you to find the water bear from the samples? Is it hard to find them under the microscope? How much time did the experiment overall take?
AND thank you loved the video :)
+Tala Agha In the first half of the video we spent about an hour collecting samples. We searched through the samples about an hour as well. We didn't find anything.
In the second half of the video, I spent about 10 minutes collecting samples. I let them soak in distilled water for a few hours. Placed it under the microscope and found a water bear in a few seconds. That last clip is pretty much real time.
Finding water bears in the microscope is tough at first. That can be hard to spot if you don't know what you are looking for. My very first time took a few days. Afterwords it became easier. IT just takes practice and patience :)
Good luck out there!
@@mike.likes.science thas CRAZY
I've been looking for a companion (pet but I don't like the word) that can live life as long or longer than I. I always though reptiles or some birds would be good. But I hate parrot screeches and I don't like snakes. So a tardigrade would be amazing, as I've heard they dn near live indefinitely. I understand that they technically have a lifespan, but the fact that they're able to dehydrate themselves to go into a stasis mode impresses me. To think I could have a buddy that I grew up with could still be around when I grow old. It's a pretty awesome idea, if you ask me.
You spend the entire video looking for water bears and when you finally do, the video ends. What the hell?
Need an idea for a tardigrade/water bear science experiment for 7th grade, any ideas? It would be super helpful :)
+Supreme Dalek Fire nukes at them and see if they can survive :-)
So, they survive everything BUT tap water...
XD
Great video! :)
A Tardigrade hi
shut your mouth
oh sorry didn't see you were a tardigrade bro
4:09 What was that little beetle-like creature on the right of the water bear?
If we eat them? Would they survive in our stomach?
Just wondering. 🤔🤔
Wow amazing its really good effort
So there is moss that bears water bears (this is barely believable).
NTeamEN I can understand the skepticism about Tardigrades. Just describing them to people, they sound like a creature from a sci-fi film or something. But it's true. Water Bears are real. They can be found in moss, lichen, leaf litter, bodies of water, sand, and more.
Coma Niddy Don't worry, I was just being a dork with bad puns, I know that Tardigrades are real and pretty awesome at survival (being resistant to a lot of heat, near absolute zero temperature, vacuum to some extent, lack of water to name a few).Anyway, I know they're real :)BTW check your email inbox :)
Coma Niddy you seriously didn’t get that?
I got the puns though
Really good video thinking it was filmed in 2014
Go ahead honey.....you found a water bear!!! (lol)
I must go on a mission to climb mount everest with my sidekick, Tardigrade.
Today I found some moss on a big rock in the Park. I've told my kids that there is a water bear living inside, of course they did not believe me, and I did not think that we'll actually capture one on the microscope. Guess what, we found one! it is our first try to catch one, and we did it using an amateur microscope and from the first try! And it is actually cute.
Are they on all continents
Captain Tardigrade !!!
*we found the water bear, we found the tardigrade , we found the water bear. Its time to celebrate*
People are being like “save the trees”
I’m being like “save the water bears”
For finding Tardigrades in snowy conditions, would I look in the same places? If I go under the snow there are still some mosses and life. Will this work?
And thanks for this, super helpful and engaging.
+Rachel Wyoria Ford Hey, I haven't tried searching for water bears in the snow. I'm pretty sure you'd find them. There's only way true way to know for sure. Try it out. Let me know how it goes!
+Coma Niddy Will do. Thanks!
HELL YEAH
Waterbears: human can even survive the tap water
Why the shock at a flag pole cleat?
Can u feed them like tuna fish blood?
Lol, it must've been awkward posing for the camera at 0:22.
Your wardrobe is intense!
Very kewl
Haha, love the way yoy science.
what's that linear thing in 2:01?
+wilmor benedictos Probably a plant part.
Wow nice
Would have likd to see more of the bear
by the way they can survive over 2 years without water and enter the state that you said after 2-3 years
cross breed human and tardigrade to make a real life super man
