it goes again." now they are back and defying gravity in "upside down and inside out." how they did it. but first the "nightline 5." >> let's give these dayquil liquid gels and go. >> these are new, mucinex max. >> same difference. >> fast strength and fights mucous. >> the only cold liquid gel that fights mucous. let's end this. rush into jcpenney for the presidents' day sale. spend $25 and get discount coupons. 50% to 80% off with markdowns and red zone clearance.

they're one of the wall street banks that triggered the financial meltdown -- goldman sachs. just settled with authorities for their part in the crisis that put seven million out of work and millions out of their homes. how does wall street get away with it? millions in campaign contributions and speaking fees. our economy works for wall street because it's rigged by wall street. and that's the problem. as long as washington is bought and paid for, we can't build an economy that works for people. sanders: i'm bernie sanders, and i approve this message.

lots of celebrities sell or endorse products. but channing tatum is really taking to it the next level. tatum, who's played action heroes and perhaps most famously a male stripper, recently traveled deep into the south american rain forest for an unusual sort of market research. and he brought along abc's rebecca jarvis. >> reporter: deep inside the rain forest of ecuador i find myself dancing. with a group of amazonian women. >> i like her, she got a groove to it. >> reporter: the actor once called the sexiest man alive, channing tatum. >> thank you, thank you, thank you. whoo! >> reporter: we're here for a ritual thousands of years old. >> it smells so good. >> it does, right? >> reporter: the key to what people begin every day like this, drinking tea from the mystical quyalusim. >> oopie!

started drewing, and they do it to create community, to talk to their young, and the elder pass on the stories, can pass on their knowledge. >> it's kind of magical, the whole thing. >> it really is. >> reporter: in the united states quyusa is packaged and sold as runa. a drink channing says became his stamina secret while working on "magic mike." >> i was going through about six to seven cans. we were exhausted. >> "magic mike" surviving on runa? >> that's it. our blood was runa. it became an obsession. >> reporter: now channing says runa is an essential part of his life at home with wife, actress jenna dewan tatum, and daughter. >> i don't drink coffee, it gives me the shakes, that anxiety feeling. this is my everyday. it really has turned into a ritual. i get up and me and my wife, we wake our daughter up, we start our day.

>> it's the tatum tea ceremony. >> that's right. >> reporter: runa is marketed as a clean energy drink, differentiating itself in a $50 billion industry. the company says one bottle provides the same stimulating effects as a cup of coffee. with the added benefit of 15 essential amino acids. >> it has caffeine, it has anti-oxidants, gives you great functionality, you can feel it. >> reporter: that's tyler gage, the man responsible for bringing this tee to the masses. he first tasted it 11 years ago while visiting the amazon and believed so much in its potential, he built a company around it. >> i showed up in ecuador with this idea of using it commercially. the farmers literally laughed at us. the idea of commercial was nil. in only six years we've grown to support over 3,000 families. we'll generate almost $1 million of direct cash income to the communities. >> they're not laughing at you anymore? >> they're laughing in a different way. >> reporter: two and a half years ago a business adviser

of runa and recommend the tyler reach out to see if channing might invest in the company. >> what was that first meeting like for you? >> it was funny. because this friend of neil's asked if i wanted to meet a guy named date edd edd edd tatting channing. >> i thought they were joking. that was a character i played. this is tyler gage. >> turned out he's a real person. >> here i am. >> he happens to be way smarter than i could ever try to be. >> reporter: already a runa mega-fan, channing was in. and while clips like this on lip synch battle may go viral for a investment will have a lasting impact. so we traveled far into the jungle.

>> hola! >> reporter: and by foot. >> appreciate it. >> welcome. >> reporter: to see firsthand how this ancient leaf is making its mark on the world. ruth is just one of 3,000 farmers who supplies quyusa to runa at a fair trade price. >> she said now with selling to runa they've been able to take this important part of their culture, share it more broadly, use it to materially support their families. >> where are we going now? >> up to the runa factory. >> reporter: channing and tyler take to us runa's headquarters where all those leaves end up. >> hey! >> this is it? >> this is it, this is the dream. this is the world's first quyusa factory, exporting from the amazon. >> let's take a look around. >> let's do it. >> cool. >> this is where we do what's called withering. the process where the flavor sets into the leaf. >> in this space you say there's how much supply of runa?

month and a half supply worth of runa. >> that's a lot of runa. >> reporter: the leaves are laid out on drying beds. >> this is where the moisture gets down to 2%. >> you can feel the heat in this space. i'd say it's about 100? >> probably about right. >> reporter: then sifted and packaged for delivery. >> 100% organic, fair trade, and non-gmo. this is what it basically gets packed into. >> that's perfect. >> reporter: before it's shipped to the stores, there's the essential taste test. run by daniel in this lab. >> mmm-mmm! >> i feel like it's going to come out my nose. >> that's the kind of thick you shouldn't say. >> i always say among the 70 people of runa, daniel has the funnest job by a long shot. >> have you seen the movie "magic mike"? what'd you think of that guy? >> come on.

>> sorry, i had to. >> reporter: back at the tea ceremony, we learn there's no limit on refills. >> how many cups a day do you drink? >> i don't think in gourds, i think in pots. i drink two to three full pots a day. he said in the culture they traditionally have lots of kids. and it's part of the quyusa. gives you strength and -- >> virility. >> life force to carry forward. >> that's how i got my kid. now i understand. >> this experience of just being a part of this tea company has enriched my life to a degree that i don't even know if i can express it. i grew up in the south where i was 7-eleven culture. you know, mcdonald's culture. i just ate stuff just because it was -- tasted good. there's something beautiful about knowing where this is coming from and what the story is.

consumption that i believe is really where i hope that society's going. >> reporter: what do people say to you when you go back home, here? >> you know, it's hard. you know, it's hard to see a bunch of pictures and hear some stories and really understand it. and so i give anybody an open invitation to come on down. >> really? you've got to be careful. "nightline." >> if anybody has a lot of money and they would like for me to host a tour, i would totally do that. >> so there is a price. >> i'm buyable, straight-up purchasable. >> reporter: ladies, take note. for "nightline," i'm rebecca jarvis in ecuador. next, why kim kardashian says going from one kid to two kids has really been a difficult adjustment for her. tonight the backlash and the serious question, can two be too much for some people? later, check out the band ok

the world a president has to grapple with. sometimes you can't even imagine. that's the job. and she's the one who's proven she can get it done. ...securing a massive reduction in nuclear weapons... ...standing up against the abuse of women... ...protecting social security...

...and winning health care for 8 million children... the presidency is the toughest job in the world and she's the one who'll make a real difference for you. i'm hillary clinton and i approved this message. when you're kim kardashian how tough can parenting really be? you've got enough cash to pay for a wall of nannies, right? now kim has come out to say that going from one to two children has been genuinely tough on her. not everybody is sympathetic. her comments have generated some real dialogue.

>> reporter: not many parents with two young kids spend their nights like this. at a mega fashion show in new york. but that's just what kanye and kim did tonight. seen here in this video from "title." even with all the help she can afford, kim now saying baby adjustment. sleep. in reference to balancing the needs of her newborn son with those of her toddler daughter north west, seen in this instagram photo. every waking second i'm not with the baby i'm with north. i feel like i go into overdrive to give my daughter attention and make her feel loved. of course as the internet was quick to point out, she probably has lots of help. but there are the sympathizers too. kardashian's comments sparked new dialogue about being a parent in the modern age. when couples go from one child to two or more, the pressure to provide a perfect upbringing for each one has made parenting

it can look a lot like this. corey white and her husband dan gibson are parents to four kids. >> this is levi. olivia. jackson. and then we have emily. if you can see us all. >> reporter: earlier this month the couple posted this video to facebook. showing the ontario mom juggling to put her toddler and three young triplets to bed. the post quickly racked up over 66 million views on facebook. finding out they were expecting triplets was a total shock for corey and dan. myself. and when i got there and they told me it was triplets i didn't know whether to laugh or cry. >> reporter: but sometimes life works that way. husband melvin. they had one son, melvin, named after his father. and decided to go for one more. >> we got together, we decided i mean, that was kind of the number we were hoping for. >> easy. >> reporter: instead -- they got

>> we went into the doctor and he said, well, there's two. and my response was, two what? she was like, two babies. >> i was looking at the screen. i said, yep, i can see two. like a national geographic of watching babies, some wild animal. yeah, there's two there. >> reporter: raising their three kids isn't cheap. the average cost for middle-income families to raise a child in the u.s. is more than $245,000. by the time their kids are 18, nicole and melvin will have spent more than $736,000. and they haven't even paid for college yet. >> child care is extraordinarily expensive. food. food is a biggest expense. >> reporter: it's not just everyday costs that add up. those untenable expectations. a study shows that 53% of moms feel overwhelmed trying to create perfect life for their children. and 46% have incurred debt as a result.

to put their kids first. and even put themselves in debt in order to provide certain opportunities. >> reporter: this idea of perfection is taking a toll on more than just the bank accounts. 44% of moms say they argue with their partner over money. at least some of the time. the percentage jumps to nearly 50% in households with two or more children. >> i think the more personalities you have in the household, the more conflict there will be. and every parent has a different way of parenting. >> reporter: and when it comes to having that second child, women and men appear to have different experiences. according to studies, women and men differ slightly in happiness after the birth of their second child. >> we have a lot more women who are in the work force. and a lot more women who are, you know, earning the living that the family is living off of. and then on top of that, they want to be the good mother, the good wife, the good friend. >> reporter: even if it's hard,

raising children is the most amazing job in the world. especially if they've had trouble conceiving. on tlc's new show "rattled" -- >> oh, hi, baby. >> reporter: first-time parents ashley and tyson gardner struggle with infertility for eight years before giving birth to two sets of identical twins, all girls, through ivf. a 1 in 70 million chance. >> just having them makes us appreciate every moment. especially having quadruplets. where some people may not be super grateful for such a hard situation, for us we're like, yay! we're so excited. like they all four have poopy diapers and we're like, this is great! >> we are just running a million miles an hour. constantly. >> it is very expenseive. formula, diapers, clothing, wipies, medicines, doctor visits. mutt fly that times four. sometimes you're spinning into the ground.

overwhelmed by the challenge of raising four babies, ashley's sister turned to the internet for help. she helped the gardners set up a facebook page and blog called the gardner quad squad which helped the couple with donated baby clothes and supplies. thankfully for the mcnamaras the newborn phase is behind them. the twins turned 3 in may. it's no walk in the park. both nicole and melvin work full-time, mostly from home. >> work is always here. after the kids go down we go back to our offices. we have to be intentional about saying, okay, this is the kids' time, this is our time. >> reporter: these parents all say they wouldn't trade it in for the world. >> everybody's going to have their ups and downs, their struggles. but children are the greatest blessing ever. no matter how hard the struggle is with them, they're worth every second of it. >> reporter: for "nightline," i'm reena ninen in new york. >> our thanks to reena. the gardner family is featured in thehow "rattled" which

let's end this. guys, it's just the two of you. the setting is just right. there's something in the air. but here's the thing: about half of men over 40 have some degree of erectile dysfunction. well, viagra helps guys with ed get and keep an erection. ask your doctor if your heart is healthy enough for sex. do not take viagra if you take nitrates for chest pain or adempas for pulmonary hypertension your blood pressure could drop to an unsafe level. to avoid long-term injury, seek immediate medical help for an erection lasting more than four hours. stop taking viagra and call your doctor right away if you experience a sudden decrease or loss in vision or hearing. ask your doctor... ...about viagra.

there are those who say we cannot defeat a corrupt political system and fix a rigged economy. but i believe we need to lift our vision above the obstacles in place and look to the american horizon. to a nation where every child can not only dream of going to college, but attend one. where quality healthcare will be a birthright of every citizen. where a good job is not a wish, but a reality. where women receive equal pay and a living wage is paid to all. an america where after a lifetime of labor, there is time for rest and grandchildren. a nation that defends our people and our values, but no longer carries so much of that burden alone. i know we can create that america if we listen to our conscience and our hearts and not to the pundits and the naysayers. i'm bernie sanders. i approve this message,

finally tonight, one of the coolest music videos i've seen in a while. try watching this without smiling. don't stop can't stop >> this music video shot

racking up millions of hits tonight. don't stop can't stop >> the song is "upside down and inside out." the band is ok go. the video features the band members and a few dancers in flight attendant uniforms performing stunts while flying in a plane thousands of feet above the earth. >> it is truly unbelievable that everything just came together. >> reporter: it required three weeks of training at a russian cosmonaut center. >> we flew in a plane that basically goes like this. wonderful is 20 seconds of double gravity while the plane is throwing you into the air, then you feel weightless for 27 seconds while you go up, over the top, and sail back towards the ground. >> after the maneuver you've lost altitude so it takes four or five minutes for the plane to gear back up to do it all over again. >> we wanted the whole video to be weightless. we cut up the song into eight chunks, each short enough to fit into a single period of weightlessness. we'd perform them in order, then later cut out the four, five-minute waiting periods.

creative videos. here we go here we go >> reporter: they ran their way into the national consciousness more than ten years ago with "here it goes again." then they turned a car into a musical instrument for their "needing getting" video. i won't let you down >> reporter: and they wowed with these impressive aerials in "i won't let you down." upside down >> reporter: this shoot presented some very specific challenges. >> most people's response to weightlessness is to start swimming. >> the other is just puking. so over the course of 21 flights we had about 58 unscheduled regurgitations. you met the now you >> i'm sighing big sighs of relief that it happened. don't stop can't stop >> great video. thank you for watching. morning. as always we are online 24/7 on
