(fan spins)
- All right. It's getting faster.
Whoo!
Got it!
Now, I've tried this on a small fan,
but at the end of this video
I'm gonna be using this guy.
We're gonna make this thing launch.
This is the fidget spinner.
Of course you've all heard of it.
I was trying to hold out as long as possible
without getting one of these.
I didn't know what I would think of this thing.
They're kind of cool and addicting
and I hate it, 'cause I spin it all day.
If you have one of these things comment below
what your longest spin is. I would love to know.
I've heard of people get like five to eight minutes
spinning this thing. I don't believe it
unless I have a really, really crappy one.
I wish someone would make a fidget spinner
with a counter on it to tell me how many times it's rotated,
that would be awesome.
Mine's a little crappy, I got it on Amazon
and it's already broken.
I got one of the $10 wonders, so.
Oop.
And because I drop it all day long.
Now, the fidget spinner is totally like
a helicopter propellor, that's what I always think of
when I spin this thing, I'm like, it should fly
out of my hands. And then I got thinking, okay
let's add
blades to it.
So I taped these duct taped blades to it
to the point where I can spin it in my hand
without getting a paper cut.
And warning at home, you could get a paper cut doing this.
So my first model that I tested
was all cardboard, didn't work.
The paper allows it to slice through the air
but also get lift at the same time.
And it's going fast enough that you actually don't need
big props here. So there's three blades
and it's gonna spin this way.
I'm not even very good at spinning these very fast, but
(blowing sound)
you can already hear
(blowing sound)
with a light spin
how fast that's going.
And you've heard of people making these go
like a couple 100 miles an hour, apparently, with air cans.
So I had to figure out the best aerodynamic shape
to go on the fidget cube, and then I got my first fan,
the small, put to level three,
and I'll show you, if I just place this
in the center of the fan, it will start spinning on its own,
it'll actually try to get lift.
(fan spins)
And I'm gonna let it go so you can see here.
You'll see it starts picking up speed.
It could take a minute so we might cut out
a little bit for ya, but it's pretty incredible.
(fan spins)
And you can see it start wiggling around, too.
So you can see it moving and it'll--
(paper hitting fan)
See, there it goes. So, it gets a little speed
and then it messes up and that's the problem.
This fan barely has gotten it above two inches
and I think there's something here,
I don't know the science behind it,
we need a guy like Veesas here,
but it traps some sort of pressure here
because of the curve.
And see the indent of the fan, it goes down.
So this is like a cool landing pad,
it works out on my fan that it allows it
to go up to here and then it always does this like you saw.
So, next, we're gonna try this.
And this is gonna be our next test.
It's even got a little landing pad here.
(breaking glass)
Oops. It got a little takeoff pad, I can't remove it
because it's screwed in. I think it actually'd
be better if it was off. But we are gonna try this next.
We're gonna fire this baby up on level three.
It's gonna get loud.
(fan spins loudly)
No, that one's not getting air.
(fan spins loudly)
Nope.
(fan spins loudly)
So...
Oh, it's going!
Ha!
Ah.
And once it starts going up I'm gonna move the fa--
Oh!
So have fun turning these little fidget spinner toys
into flying saucers.
(blowing)
Ow.
And be careful of paper cuts, seriously.
They'll get ya.
Whoosh.
