-Now, I love inventions,
and I'm okay with kids. So we found some of the best
and brightest kids out there, and I think
you're gonna be really amazed at what they came up with. Let's meet our first inventor.
Come on over here, Dominic. [ Cheers and applause ] ♪♪ Hi, buddy.
How you doing? -Good.
-Nice to meet you. Thank you for being on the show. How old are you, pal?
-I'm 8 years old. I'm 8-years-old,
and I'm from Ontario, New York. -Oh, cool.
Now, what did you invent here? What is the name --
What is this invention here? -It's called
the Shorty No More 360. -Shorty No More 360.
-Yep. -Now why did you come up
with this invention? -Well, I'm sick of being
the shortest in my class. [ Audience "Awws" ] -Yeah.
So you made this invention. How does it work?
Show me how it works. This is for you.
You have a pump there. You brought these for me?
That's very nice, thank you. -You're welcome. [ Light laughter ] -[ Laughs ] [ Cheers and applause ] -Invention's great. Wow. [ Chuckles ] Oh, my gosh. How'd you come up with this? Just 'cause you want
to get on the rides? [ Laughter ] -I'm shortest in my class.
-Yeah, I know. This is gonna be --
This is fantastic. Dominic, you are short no more. Let's see how it works. -Wow.
[ Cheers and applause ] ♪♪ Dominic, Shorty No More! Dude, you're awesome!
That was fantastic. I love this. [ Cheers and applause ] Now, your invention
solved a problem for people who want to be
a little bit taller, but you want to see an invention
I came up with that solves an even bigger
problem for guys like us? Watch.
Bring this over. Check this out. Everyone wants to hang out
with all the cool guys, with the cool shoes. But we don't
always have time for this, and it could be hard to keep coming up
with good excuses, okay? So, not anymore,
with the Excuse Dice. Okay?
You just roll -- You roll the dice,
and you have an instant excuse. So watch.
Ask me -- Ask me if I want
to hang out with you. -You want to hang out with me? [ Audience "Awws" ] -Sorry, I can't because I have
to babysit my nephew's flowers. [ Laughter and applause ] Ask me if I want to hang out
with you next week. -You want to hang out with me
next week? -Oh, I wish I could,
but I, uh... have to hug
my neighbor's Chihuahua. [ Laughter ] Hey, take care, buddy. Take your invention that way. [ Cheers and applause ] Come on.
Who's next? Hi. Come on over here!
Hey. How you doing? Just gonna take these off
before I fall into something. Hi.
What is your name? -I'm Gitanjali. -Gitanjali, where you from?
-I'm from Lone Tree, Colorado. -Now, you came up
with this cool invention. I heard that Google saw it,
and they want to make a documentary about you
and the invention. -Yes. Yeah. [ Cheers and applause ] -Are you kidding me?
How cool is that? How cool are you?
How old are you? -I am 12.
-Gosh, you are so cute. That's so awesome.
-Thank you. -What is the invention? -So I created a device,
called Tethys, which detects lead
in drinking water faster and cheaper
than current methods. -Wow.
Good for you, man! -Thank you.
[ Cheers and applause ] -Awesome!
-Thank you. -All right.
And how does Tethys work? -So, essentially, it uses
carbon nanotube-based sensors to detect hazardous gases
in the air. [ Laughter ] -Obviously.
We all knew that. -So, actually,
the inspiration was from hazardous gases in the air,
but I use it now -- I've expanded it to test
for lead in water. -This is cool. All right.
-Yeah. -And then,
it hooks up to an app? -It does, yeah.
I created this custom app from MIT App Inventor
for Android phones. -You're 12 years old?
-[ Laughing ] I just want any of your --
You just -- I want to touch you.
You're just, like, so smart. Wow!
I hope it rubs off on me. -Thank you.
-Wow. God, when I was 12,
I don't know what I was -- I was lip-syncing in my mirror
in my bedroom. [ Laughter ] This is a --
All right, so let's try it. What do we do?
-So what you do first is -- It's a very easy test. So you take this cartridge,
which is in the device, and just snap it out of place. -Uh-huh.
-And, so obviously, one of these two beakers
has lead and one doesn't. -I'm assuming.
[ Laughter ] I'm assuming. It wouldn't be that one, right? -Don't drink it. [ Laughter ] -I have the idea.
Okay, yeah. All right.
And what, you just put it in? -Yeah, and you just let it
in there for like 3 seconds. It's a very quick test.
-Okay. -And after that,
you can just take that out and put it back in.
-Okay. -And so how it works is,
these carbon nanotubes are developed
to make chloride ions. So when it's dipped
into water containing lead, the lead in the water
binds to the chloride ions... [ Laughter ] ...and it forms
lead-chloride molecules, and that increases
the amount of resistance to the flow of current
and decreases the conductivity. [ Laughter ] So I found that
the conductivity drop is co-related to the severity
of lead compounds in water. -Yeah, yeah, yeah. [ Laughter, cheers, applause ] I just got
taken to school right there. Fantastic. -So it's based
on bluetooth connection, so all you have to do
is click "Check status." -Okay.
-And it gives you the results. -Check status.
[ Gasps ] Look at that. Mine's safe.
[ Cheers and applause ] Look at that. Hey, that's a great, great,
great invention, pal. Congratulations.
-Thank you so much. -Thank you so much
for coming on the show. -Yeah!
Thank you. [ Cheers and applause ] -This is incredible.
This is saving lives. This is keeping people safe
and healthy. But you know what else
is keeping people strong and healthy? Even smarter invention
that I came up with. Let's bring them out. These are called thumb bells,
okay? Here you go.
There's two for you. -Oh, wow.
Thank you. -Yeah, these are the real deal.
Yeah, "wow" is right. Yeah, I mean, this is --
Let's face it -- we live in a thumb-based world constantly texting,
pressing buttons. You could wear
your thumbs out, okay? Which is why I do 200 curls
with each thumb first thing every morning.
[ Laughter ] -I love it.
-Yeah, it's really good. It's a great invention. [ Cheers and applause ] Thank you so much. Google is making a documentary
about my invention, as well. You're much smarter than me.
Please leave, bye. -All right, thank you. [ Laughter, cheers, applause ] ♪♪ -She's got it. Let's meet our last inventor. Come on over here, Ellie.
Come on over. ♪♪ Hi!
-Hi! -Nice to see you.
Nice to meet you. Oh, my goodness. Wow, wow.
Where are you from, Ellie? -I'm 11 years old, and I'm from Greenville,
South Carolina. -Hey, welcome to the show here. What is the invention?
What do we do with these? -This is the Hula Drop Stop. -The Hula Drop Stop. Okay.
And what do we do? Do I put them on?
Do I wear them as shoes? -No, you strap them on like this very tightly. -Like this? -Uh...
-Like that? -Yeah, yeah. All right.
[ Laughs ] Sorry. Grandpa's -- Grandpa's
just getting used to this. [ Laughter ] Here we go. All right,
so that goes on there like that? -Mm-hmm.
-And then, this one...same deal. Now, how did you
think of this invention? -Well, I love hula-hooping,
but it's annoying that every time it falls, I have
to bend down and pick it up. [ Laughter ] [ Cheers and applause ] -Oh, my goodness. Yeah, it's a real bummer.
Yeah, yeah, yeah. This makes it much easier
if you put these on. [ Laughter ] All right. All right, so now --
So, now -- now what do I do? [ Laughter ] If there's a fire,
we're in a lot of trouble. We're gonna really
help each other out. Okay.
Now what do I do? Am I doing it right?
-Yeah. Just bring the hula hoops. So, we got the hula hoops. -So you just... [ Laughter ] -Great. It's genius.
I love it. Dude, it saves me
about 3 or 4 inches. It's unbelievable. [ Laughter ] ♪♪ This is unbelievable!
Yeah. Oh, you know how to do it. [ Cheer and applause ] Hey, it's fantastic!
I love it. I love it.
You're so cute. Thank you so much. Let's bring all
of our inventors out here. ♪♪ [ Cheers and applause ] Guys, I do have one more thing
I want to show you. We here at "The Tonight Show"
love supporting smart, talented kids
like yourselves, and we want to see you
keep exploring, creating, and changing the world,
so we're giving each of you $5,000 to help
further your education. [ Cheers and applause ] Thank you, pal. Dominic, that big check's
