good evening. we begin here tonight with what lurks beneath the surface. sharks. concerns about an intensifying threat on the nation's beaches. just as millions of americans grab their boogie boards and head for some labor day weekend fun. coming face-to-face with a deadly predator and living to tell about it, abc's zachary kiesch wading into troubled waters. >> reporter: for some, labor day weekend is synonymous with that last summer beach getaway. but you may want to think twice before you get into the water. this summer shark activity at america's beaches was a little too close for comfort. >> mom, mom! >> reporter: in some cases they came for the food, and left with the flesh. >> sharks, the latest scare, you're looking at it. >> shark attacks on two separate beaches -- >> reporter: last month a

13-year-old boy and a 12-year-old girl bit no one waters off two separate beaches in the new york city area. >> it was like one second it went like that. then it just let go immediately. >> right there! >> reporter: this sighting off the coast of orange county. >> holy [ bleep ]! >> reporter: aing cross the country, in cape cod, a 61-year-old man spent nearly two weeks in the hospital after a shark left puncture wounds on his torso and leg. >> call it longnook beach for a subject possibly bitten by a shark in the thigh -- >> reporter: william litten told the associated press he was swimming in eight to ten feet of water when he was attacked. two nursing students on the cape provided care. >> as we got closer we realized he had been attack ted by a sha, needed immediate medical care. >> we grabbed the towels, tried to stop the bleeding -- >> reporter: six surgeries later litten is in a boston rehab clinic where he faces weeks of treatment and is still searching

for farmcy. >> there's been quite a bit of shark activity around the northeast this summer. >> reporter: nick whitney, shark researcher, says sharks have been coming closer to shore in recent years in search of food. >> white sharks gain protection in the late '90s so offall you have this confluence of a lot of seals in the area and then more sharks coming in to feed on seals. >> reporter: so far this year there have been 37 unprovoked shark attacks worldwide, 21 in the united states alone. we aren't in the clear yet. in places like florida, researchers say shark attacks historically occur more often in september. >> we think that probably the reason there's a peak in september is because in florida, in september is when we get some of the more tempestuous weather -- >> reporter: last month dustin though bodily battled a shark attack on, of all days, friday the 13th. >> definitely weird being right back at the spot it happened. >> reporter: dustin and 8-year-old son emerson were at

fernadina beach in florida. >> i was out probably 20 yards. >> reporter: he says while helping his son surin two feet of water, it happened. >> felt something grab on my foot. turned around and swung. hit him right above his own eyes. >> reporter: his son made it to shore. >> i was like really confused. he was like, like swinging his arm -- >> reporter: leaving behind bloody footprinted on the sand, dustin alerted other swimmers about the shark, but according to witnesses, not before another person was attacked. >> the shark, he could have held on, he could have kept going, he could have kept jerking, probably taken my foot if he wanted to. but he let go. i guess i wasn't on the menu. >> reporter: since the 1990s a whole range of shark species have been protected by the federal government. researchers say it's a fake for responsible for driving up the animal population. but it's not good for swimmers. >> in general the shark populations are doing a lot better on the east coast of the

united states than they were, for example, 20 years ago. >> reporter: a research project led by world-renowned shark expert dr. greg schomo is under way in cape cod. in 2016, he invited my colleague, david wright, to cape cod on a shark-tagging trip of his own. >> this is the tag right there. all right? we'll pull that magnet off which will turn it on, that will ping away for 10 years. >> reporter: those pings detected by audio buoys positioned along the shore signaling that a shark is swimming by. >> see, that's a couple of little guys -- >> reporter: he and his fellow researchers check them regularly. now they're in the final year of their five-year research project. up overhead -- >> we're at high altitude now -- >> reporter: a spotter plane casts a birdseye view and sees a shark prime for tagging. a go pro attached to that pole gives us an up-close view of the

shark. >> we're fingerprinting it. oh, oh -- oh, wow. yeah. let's get the tagging pole. starting to come up, hold on. >> i see him now. >> i'm ready. tag, tag, tag! yeah, yeah, yeah. >> that's a pretty good white shark, you don't see that every day. >> reporter: as majestic as these animals are, they can still pose a big threat. and yet there are some people like nikola buff and mike dornelis that thrive underwater and do stuff like this on the regular. they say don't blame the sharks. >> most of it is human error. it's our lack of understanding of getting in the water and an environment that we're not comfortable with. >> that's their home. >> reporter: and i find myself here in the open ocean off the coast of l.a. on the doorstep of their home. and these guys are dishing out tips how to avoid deadly encounters. i get the sense that you guys

get a little bit of an adrenaline rush being out there in the water? >> i've never felt more calm and more relaxed than surrounded by a bunch of sharks, believe it or not. >> tiger, tiger, turn around! >> reporter: the duo was part of discovery's "shark week." >> you can avoid almost every bad incident that happens with sharks. >> reporter: "the laws of jaws," unlocking what they call the keys to survival re-enacting harrowing real-life incidents. >> it's got to be a difficult, maybe even a learned skill to be able to actually face a shark in the eye when you're in these close contacts with them, flight. >> yeah. most people would want to swim away. that's really not what you want to do with most sharks because it's going to show the predator versus prey. >> reporter: the team has a test for me. can simply smacking the water help prevent an attack? they say depending on the moves you make in the water, you can either distract or attract the shark.

what's the difference between this kind of noise like a dead animal would make, and this more intense splashing or slapping we're talking about? >> an animal that's suffering, if it's a fish and it's twitching a certain way, i think sharks might be attracted to that. they can pick up on that energy or pulse or whatever sound it is that they do make. they'll come investigate. >> reporter: the guys convince me to dive in and learn the techniques that could prevent a fatal attack. >> what i'm going to be doing is demonstrating paddle boarder, boogie boarder, a repetitive sound. paddling. >> reporter: those little rhythmic splashes are the sounds that attract sharks. instead they say to scare the sharks away, a loud slap in the water is what you've got to do. how much force should you be using when you slap down? >> give it all you've got. you want to catch that pocket of

air in your hand. if you're coming down, give it everything you have. create a shock wave. >> reporter: back in florida, dustin's close encounter with a shark hasn't kept him out of the water. >> i can't imagine not having the beach in my life. >> reporter: for "nightline," i'm zachary kiesch. next here, getting your blink on. we're watching the fake eyelash boom. he thinks it smells fine, but his mom smells this... luckily for all your hard-to-wash fabrics... ...there's febreze fabric refresher. febreze doesn't just mask, it eliminates odors you've... ...gone noseblind to. and try febreze unstopables for fabric. with up to twice the fresh scent power, you'll want to try it... ...again and again and maybe just one more time. indulge in irresistible freshness. febreze unstopables. breathe happy. i'm missing out on our family outings because i can't find a bladder leakage product that fits.

back now with a beauty trend taking over and not much more than the blink of an eye.

false eyelashes. the must have beauty accessory. from do it yourself extensions to salons specializing in hundreds of exotic varieties. abc's marci gonzalez once again on this eye-opening story. >> going to start out with the long ones -- >> reporter: from kim kardashian tutorials to rupaul's drag race. >> my secret weapon with lashes is a blow dryer. >> reporter: twiggy's head shots. larger than life names complete with lush lashes have always been in style. >> hey, guys. i'm going to show you how to apply your lashes properly. >> reporter: now lashes, false ones, have gone from special occasion adornment -- >> as close to the lash line as possible. >> reporter: to must have everyday accessory. >> and pop it on -- >> if you have eyelashes, extensions are to you yore -- >> reporter: mark cuban tried out these lash extensions on "shark tank" in 2015. the sharks passed on this pitch

and may have missed out on more than just a new look. the market for false lashes is booming. projected to reach over $1.5 billion in the next five years. and that's just in product. for entrepreneurs like tirsa, it is much more. >> i really saw a need. that's when blink bar was born. >> reporter: she's looking to cash in with specialized salons. >> i couldn't find anyone in l.a. that was doing eyelash extensions that looked really natural. >> what makes your lashes so different? >> i think one big thing is customization. so we have over 300 different types of eyelashes. so i like to use a jeans analogy. i'm looking for jeans, someone throws jeans at you over the counter hoping that they're the right size and they may fit you. and so we really take a different approach. >> reporter: the options are seemingly endless. >> we have the coquette. we have our temptress. we select the material. so we have our synthetic lash,

our starter or basic lash. we have a lot of models who shoot all over the world and they'll use the may the mat lash. the photo shoot that day may not call for any makeup at all, so the matte really looks like it's your own natural lashes. >> reporter: instead of relying on traditional advertising, blink bar uses social media influencers like alexis choi to promote the brand. >> it is so worth it. because when i want to go outside and not wear makeup, boom, my lashes are there so it's like my number one accessory right off the bat. >> we're seeing you now without lashes. >> yeah, i don't have anything. >> reporter: alexis invited us to watch the transformation. >> what specifically are you having done? >> i'm getting temptress. >> reporter: the process takes about two hours and costs between $120 and $350. for those who aren't ready for the commitment that comes with individual extensions, there are plenty of temporary options when

it comes to adding more bang to your blink. some bedecked with feathers or l.e.d. lights. others clinging to your own lashes with magnets. >> here is basically our wall of lashes. >> ta-da! >> how hot are false lashes? >> we live in a social media-driven environment these days. everybody wants to look good for their selfies. they're not necessarily trend, they may be the new standard. >> reporter: jeffrey english was kind enough to give me my own makeover. >> we're going to take the lash and line it up with the lash lines. measure it on the lash. what we'll do is always trim from the outside. most lashes have a really beautiful natural taper where they're a little bit shorter, just a little bit on the inside, so that way it looks really natural when you apply it on the eye. we're ready to apply the false lash. i'm going to take the brush-on application dater and apply a little glue to the rim of the lash line. another good idea is to leave

the glue to dry for 15 to 20 seconds, so when you apply the lash it's going to stick right where we want it. you're not going to have it moving around a lot. take a look, before and after. >> beautiful. it is really natural. >> yep, totally. you could wear to it a family function, you could wear this to work. >> reporter: work begun, i had to kick it up a notch. >> let's pop on this lash. gorgeous. this is red carpet. >> love. >> love that. >> reporter: for those searching for their own look, custom designed false lashes. >> its adds cat eye. crisscross, straight pattern, you can choose the length. we allow the customer to choose black or invisible. >> reporter: mabel lee founded the company when she couldn't find the perfect fit. >> about when i was in university i had a false lash addiction. back then nothing was available, it was synthetic, it felt very uncomfortable. it looked fake on my eyes. so i really made it a mission on weekends to source different

products. >> reporter: when beyonce's team took notice, business took off. >> there was a celebrity makeup artist called wei lang. she was the makeup artist of beyonce. she got interviewed by "people" magazine and the headline was "beyonce buys velour lashes." we took off overnight. that was velour's goal. when we launched the business, okay, this is real, now we are solving a problem for women when it comes to lashes. >> reporter: back at blink bar -- >> okay, so she's just finishing up. >> she really builds the style. she's using a multitude of lashes. >> reporter: alexis is ready for her closeup. >> all right, let's see them. oh, they look so great. >> thank you. >> how do they feel? >> they feel so amazing, i love them. >> your eyes just pop so much. >> yeah. when i first started, it was a rare luxury. i really notice when i'm at the grocery store and i'm in an elevator, i look around and 50% of the women have eyelash extensions. which is exciting.

>> maybe a few years ago i would be almost embarrassed if someone said, where did you get your lashes done? i feel like it's become like getting your hair done, oh wow, your lashes look amazing, where do you go? i think eyelash extensions are here to stay. >> reporter: for "nightline," i'm marci gonzalez in los angeles. next here, detroit rolling out a good-bye to remember, complete with pink cadillacs. ♪ the freeway of love in the pink cadillac ♪ what do you mean it's not working out, craig? i just introduced you to my parents. psst! craig and sheila broke up. what, really? craig and shelia broke up!? no, craig!? what happened? i don't know. is she okay? ♪ craig and sheila broke up! craig and sheila!? ♪ as long as office gossip travels fast, you can count on geico saving folks money. craig and sheila broke up! what!? fifteen minutes could save you fifteen percent or more
