I'm not sure if anyone will see this, but this video is what introduced me to the field of environmental engineering six years ago, and this May, I will be completing my environmental engineering degree. I don't have have any particular anecdote to share, but I just wanted to thank Scishow for inspiring so many kids and Mike Potts for taking the time to talk about his work so passionately. I couldn't be happier with my decision to pursue this field, and I want to wish any other future environmental engineers reading this good luck!
SirChocula I thought the same thing! But it's actually three routes: the giant, aquatic evolution; the smaller, terrestrial one; and the terrestrial one with the giant head and mouth used to eat its own kind.
I had a tiger salamander as a kid! He had lost his leg and I took care of him and fed him until he was better and then released him in the wettest environment I could find. I never realized they were such a versatile species though! Thanks for sharing!
Well that kind of work makes me proud of being an environmental engineer too. It's not about only finding the problem, but work hard get the solution of it
+GuyWithAnAmazingHat I just picked Norm because he's one of the best interviewers on the show, and Hank is also a great interviewer. I thought that might lead to some interesting discussion, because they'd both know exactly the right questions to ask eachother.
Evolutionmine16 Yeah! Your argument is same as valid as saying "Smoked fish is great! We should put it a cake. Cake is awesome!" Just because two things on their own are great does not mean that they will be good in combination. Your expectation are so high now already, that most probably you will be disappointing. All hail the King CGPGrey!
JustinHale III Are you serious? His videos are complete nonsense, he talks about different things simply because the words sound similar, regardless of the ideas not having any connection with each other. I feel like all people do when watching his videos is thinking "HE IS AWESOME!", instead of actually understanding what he talks about. He changes the topic in the video without finishing the previous idea and he does that without any introduction. His script is complete BS.
Very interesting video!! Granted I don't understand a lot of the science behind it but it really makes you appreciate all the stuff that goes on to keep water supply safe!
He has the strength and speed of a tiger but he can move along the walls and ceiling like a salamander. His alter ego is Manny Maverick who used to be a professional wrestler. He quit on his own terms for some mysterious personal reason but he has to use his powers to save the city and has to confront his past while subduing criminals. After quitting wrestling he has some rough times trying to get back on his feet since he no longer has income and he ends up getting involved with drugs. He and his 'friends' break into a lab to steal needles. They don't pay attention to what they are doing and Manny uses a needle that was used to test experimental drugs on salamanders. The little bit of salamander DNA left on the needle mixed with the experimental drug and his human DNA gave him heightened smell and night-vision as well as the ability to climb on walls and breath underwater.
It's really the same problem we have here. A few years ago, the chromium steel processing plant the next town over closed down and there was this huge discussion about what to do with with the tailings. Things were made even more complicated by the plant being right next to Sweden's largest lake.
Gotta agree with Hank, it's not why, it's how. Not just with the salamander, but generally speaking how is usually the more interesting question than why.
The blotched tiger salamander (Ambystoma mavortium melanostictum) lives in Montanna. The salamander you have here is a very nice example with wonderful skin patterns.
Definitely cool episode. Loved learning about the water problems and the mining problems. That salamander was the best though. :) It's like a choose your own adventure salamander. :D - Heidi
This was really interesting! You should have an aerospace engineer come onto this show because I'm interested in it and I would love to learn more about it :D
I understand that you're going for an intimate nature for the talk show, but I think it would be nice if there was at least some compression used to make the quiet sentences louder. Luckily my sound system is designed to play back low-level signals at an audible level, but I imagine a lot of people have a hard time hearing some parts of this video, and the louder moments can get a bit too loud. Or perhaps a more sensitive mic on a boom stand on either side, placed somewhat farther away from the people. I don't like being a complainer though. This is still an enjoyable video, I'm just sharing my thoughts on how I might set up the sound
If the material that polluted came out of the mine. Why can´t it be put back on the mine ground. If it was there to begin with. Why is it now a contaminant? Is there something that turned from innert to reactive? some process in the mining operation?
Calo Q. while this might not be 100% correct i believe it has to do with the fact that you are taking what was solid rock and then grinding it up to extract what you want (metals ect) and then the waste is now in a soluble form. also toxic materials used in processing aren't always extracted. something similar to en.wikipedia.org/wiki/Acid_mine_drainage
Calo Q. Adding to the cocktail mix, cyanide compounds are often used to leach gold out of ore and can present a huge problem if not properly contained.
Is the answer containment? indefinite containment. or is there a process to turn the materials innert again? I know of some bio processes that can turn even radioactive materials innert? but I know not of these metal poisons. Are the poisons too diluted? or can the waste also be mined to use the metals on other industrial processes? Cost vs benefit?
You kept remarking on the salamander's face, but you didn't show us what you were seeing. I thought at least once you took the snapshot you would show it.
I guess this is how the axolotl evolved. Remaining in the larval form must have had some advantage over full maturation. Over time it gave up metamorphosis altogether. Strangely, when exposed to iodine, axolotls will develop into something very similar to a tiger salamander.
What is a good major to study in college/uni? Im interested in the environment, climate change, physics and engineering. But Idk which major is actually the best to find a job that can make a positive impact on those issues
why do they add chemicals to mine waste? In cliff mine dump site there is just a massive mountain of rocks from inside. I did not know they did that. can anyone explain to me the process and reason for I am new to this topic.
Hank i was wondering why when you look at say for example break lights and when you look away and blink the image of the light lingers in your line of sight
It's because our light sensitive cells can take some time to "re activate", so to speak. They detect light using a reversible chemical reaction, but the time it takes to revert from the "light detected" to the "can detect new light" state can take some time if the light was very bright. I think.
can someone please cover the "breathing thru the skin" thing? i would hate to pick up a salamander and accidentally suffocate it b/c of the oil on my skin.
#Scishow#HankGreen Please make a video about earthquakes in Nepal~ It caused so much destruction only because of the weak buildings and abnormally shallow earthquake? why do aftershocks happen?
I would love to watch this but all youtube videos are displaying black screen and playing only audio and various annotations but none of the actual video.
Would have been nice to show us the salamander's face. Was anyone else worried about Jessi's hand movements while talking, that salamander must have been freaked.
i'm so curious about it's face i googled it and I regret it... its eyes and face... give me chills.. maybe because i'm not a frog person... but it have amazing color and amazing option of life cycle
Oh my Hank, I was sure you'd know how to take proper photos in landscape mode with your phone. ;-) Please don't tell me you shoot videos like that also? :-D
Interestingly, It is possible that Mike's work indirectly HARMED native ambystoma species rather than helped them. These species depend on temporary pools of water referred to as 'vernal ponds' to reproduce. Damming and other hydrologic practices actually contribute to the drying up of these naturally occurring ponds which are independent of the streams, rivers etc. which Mr. Potts' work focuses on. Stream restoration is important, but focusing on those ecosystems alone can indirectly diminish marginal wetland habitat. It is likely that the milltown dam actually reduced much of the tiger salamanders' breeding habitat.
"With special guest Jessi" Really? She's on every fucking day you film. Why isn't she just another person on the show? Does she just keep forcing you at gunpoint to come back? Are we ever going to see anyone else?
Um, no. He is just one of the millions if people that do not consider the possession of the latest and greatest cell phone to be a reflection if their worth as a human being. Honestly, if your cell phone is perfectly adequate for the purpose you need it, why shell out money for new one?
Lauren Cress Chill out girl scout. I never implied anything about the worth of a human being being related to the phone you have, and I certainty don't think that there is anything wrong with an older phone. Just been awhile since I saw a 4/4s, that's all. Not everything is a societal issue, you know.
I'm not sure if anyone will see this, but this video is what introduced me to the field of environmental engineering six years ago, and this May, I will be completing my environmental engineering degree.

Hank! When you say 'look at his face'... SHOW IT TO THE CAMERA! Ya silly billy ._.
This thing is a pokemon... with 2 evolution routes.
SirChocula yes that is the closest comparison
I was just about to say this thing sounds like a real life eevee :)
SirChocula I thought the same thing! But it's actually three routes: the giant, aquatic evolution; the smaller, terrestrial one; and the terrestrial one with the giant head and mouth used to eat its own kind.
SirChocula like eve, or evee... been too long
A poliwag can become a polytoad or polywrath, similar to this! Very cool interview.
I had a tiger salamander as a kid! He had lost his leg and I took care of him and fed him until he was better and then released him in the wettest environment I could find. I never realized they were such a versatile species though! Thanks for sharing!
Cule Chick Oh yeah, they didn't even talk about how salamanders can regrow their limbs. Amazing creatures!
tilywinn They have a video on that amazing ability already.
Just checked superfund sites and I have three in my town. One is about a half mile away... awesome.
Well that kind of work makes me proud of being an environmental engineer too. It's not about only finding the problem, but work hard get the solution of it
I loved all the new information in this episode! Wow. I'm impressed with the ground water projects. And those salamanders are so interesting.
"Slick the Tiger", Ooh!, "- Salamander", aw...
I really like those talk. So interesting to watch and listen to.
I do groundwater remediation. This is really important.
I think Hank and Norm from TESTED should get together and talk about... like... anything. It would be amazing. They're both great people.
Evolutionmine16 Why not go straight to Adam, I'd love to see that.
100% agreed.
Then throw Michael from VSauce and you'd have the best show ever.
+GuyWithAnAmazingHat I just picked Norm because he's one of the best interviewers on the show, and Hank is also a great interviewer. I thought that might lead to some interesting discussion, because they'd both know exactly the right questions to ask eachother.

I read Slick's part of the title like some superhero wrestler name. Slick "the Tiger" Salamander.
He has the strength and speed of a tiger but he can move along the walls and ceiling like a salamander. His alter ego is Manny Maverick who used to be a professional wrestler. He quit on his own terms for some mysterious personal reason but he has to use his powers to save the city and has to confront his past while subduing criminals.

camera guy is fired. everyone got to see the face, except us..
I really like this episode. Mike Potts seems like a really cool guy
You should have Mike on more stuff! He was very good at talking about that stuff :)
It's really the same problem we have here. A few years ago, the chromium steel processing plant the next town over closed down and there was this huge discussion about what to do with with the tailings. Things were made even more complicated by the plant being right next to Sweden's largest lake.
This is so cool that is what want to go into and what I'm going to get my undergraduate degree in. I'm geeking out so much!!!!! Thank you scishow!!!!!
So, given the whole ground water surface water exchange. Fracking doesn't seem like a good idea.
So I might be the only one here to say this... Mike Potts is CUUUUUUUUUUUTE! He kinda reminds me of a young Grissom from CSI.
SAN VAL So cute. And adorably nervous.
Gotta agree with Hank, it's not why, it's how. Not just with the salamander, but generally speaking how is usually the more interesting question than why.
I got a little excited since I live in Butte.
0:16 "Today we have Mike Potts who is-"
"AN EXTREMELY HOT MAN."
I had a Tiger Salamander for 9 years. His name was Yoshi. Coolest pet ever when I was growing up.
Multiple routes of maturity!
I would love it if the team could circle back with the scientists they interviewed over the years. Check in on their progress and new projects!
The blotched tiger salamander (Ambystoma mavortium melanostictum) lives in Montanna. The salamander you have here is a very nice example with wonderful skin patterns.
Hank's sign off was great this time!
Definitely cool episode. Loved learning about the water problems and the mining problems. That salamander was the best though. :) It's like a choose your own adventure salamander. :D
- Heidi
I always fast-forward to Jessi, she's the best.
This was really interesting! You should have an aerospace engineer come onto this show because I'm interested in it and I would love to learn more about it :D
I love salamanders. They are the cutest of the amphibians :-)
LiquoriceLover Chameleons are my fav, but they're reptiles
LiquoriceLover I like my charizard
***** I totally agree with you! ;-3
this was great
that sign off was legendary 15:58
in this episode hank is with a cool animal, some cool people and they discuss cool things. Cool.
Is the whole two paths to maturity unique to the tiger salamander? Such epic animals!
That is the most interesting salamander i've ever heard about.
SciShow Tell Hank we need that picture!
I am going to go ahead and apologize for being superficial but I must say Mike is HoTT

I didn't realise Tiger Salamanders were that big.
If the material that polluted came out of the mine. Why can´t it be put back on the mine ground. If it was there to begin with. Why is it now a contaminant? Is there something that turned from innert to reactive? some process in the mining operation?

Thank you for the info. (What a terrible cocktail) arsenic sulfur and lead.

12:58 Hank's mind = blown
You kept remarking on the salamander's face, but you didn't show us what you were seeing. I thought at least once you took the snapshot you would show it.
I owned axolotls, I knew all that stuff, wish they'd have mentioned more about neoteny or even mentioned it
Mike Potts more like Mike Hotts
Is the expression of hox genes responsible for the polymophisim in the tiger salamander?
Tiger Salamanders, the Eevee's of real life.
Aww it's so cute!!!
Has he heard the song you wrote about Butte Montana, Hank?
I guess this is how the axolotl evolved. Remaining in the larval form must have had some advantage over full maturation. Over time it gave up metamorphosis altogether. Strangely, when exposed to iodine, axolotls will develop into something very similar to a tiger salamander.
What is a good major to study in college/uni?
Im interested in the environment, climate change, physics and engineering. But Idk which major is actually the best to find a job that can make a positive impact on those issues
This is exactly my problem..... I am thinking of changing my Environmental Science Major into an environmental engineering
why do they add chemicals to mine waste? In cliff mine dump site there is just a massive mountain of rocks from inside. I did not know they did that. can anyone explain to me the process and reason for I am new to this topic.
Jessi's catch phrase should be "Yeah, Yeah."
DAMMIT for a second there I thought you guys brought a tiger on the show.
besides the point but the environmental engineer is unbelievably cute aka good looking aka hot. omg.
Hank i was wondering why when you look at say for example break lights and when you look away and blink the image of the light lingers in your line of sight

Émile Jetzer Awesome! Thank you
So Hank is probably the last person left with an iPhone 4/4s
JuanCanahui My 4S is three and a half years old...
I have an iPhone 4! I'm impressed that I've kept it alive this long :S
can someone please cover the "breathing thru the skin" thing? i would hate to pick up a salamander and accidentally suffocate it b/c of the oil on my skin.
Hi, under 301 club
#Scishow#HankGreen
Please make a video about earthquakes in Nepal~
It caused so much destruction only because of the weak buildings and abnormally shallow earthquake?
why do aftershocks happen?
These salamanders are like the Evees of the real world.
Were Jessi sarcastic when she said they were related?
the 1annex don't think so since hank says she introduced them
I would love to watch this but all youtube videos are displaying black screen and playing only audio and various annotations but none of the actual video.
Jedonai I can usually fix that by restarting the browser. You may have to update something like flash?
Would have been nice to show us the salamander's face. Was anyone else worried about Jessi's hand movements while talking, that salamander must have been freaked.
Hopefully those dams go away intentionally * Dambusters music plays *
berkley pit could be used to make bateries
i'm so curious about it's face i googled it and I regret it... its eyes and face... give me chills.. maybe because i'm not a frog person... but it have amazing color and amazing option of life cycle
i thought he was saying there's a scishow for kids and mike..
can Sci Show tell me our biggest enviromental problem
The level of awkwardness
The main question that causes me the video is: he grew up in love with his cousin, right?
That probably would have happened to me!
bro what
Oh my Hank, I was sure you'd know how to take proper photos in landscape mode with your phone. ;-)
Please don't tell me you shoot videos like that also? :-D
I've looked up Butte, MT on Google Earth and this Berkeley Pit looks freaky.
So tiger salamanders are Eevees of real animals.
Please Hank, close ups!

You have a good point but I doubt he built that damn in 1908 and making water less poisonous is usually a good thing
hot guy

Not with all that cooling water around.
affablegiraffable go get a drink :p
why do cats like to stand inside of circles?
Yo, where are the cookies i was promised? :O
I have a pet tiger salamander names Sally.
Someone send this good man and new iphone 6 or nexus
