STEVE SPANGLER: All right.
00:00:00
So the question today is how
quickly can you get the water
00:00:03
out of the bottle.
00:00:04
It's a clever little trick.
00:00:05
I want you to think of this
as not a plastic bottle, a
00:00:09
one-liter bottle.
00:00:09
Pretend like it was glass, so
you can't turn it over and
00:00:12
just squeeze the water
out like this.
00:00:13
You have to let it flow.
00:00:15
How do you get the water
out of the bottle as
00:00:17
quickly as you can?
00:00:18
Well, take a look at this.
00:00:19
You're pretty well limited by
the fact that as the water
00:00:22
goes down, the air goes up.
00:00:23
You have to remember it's
not an empty bottle.
00:00:25
There's air inside the bottle.
00:00:27
So how can we get the air to
come in and the water to come
00:00:29
out exactly at the same time?
00:00:32
If you could, the water would
come out pretty quickly.
00:00:34
And I've got some ideas.
00:00:36
I'm Steve Spangler.
00:00:38
And I'm all about making
science fun.
00:00:40
For the last 20 years, I've
been teaching ways to turn
00:00:42
ordinary science experiments
into unforgettable learning
00:00:47
I have an amazing team who will
do whatever it takes to
00:00:49
affect the way people
think about science.
00:00:52
And to do that, I live
by one motto.
00:01:04
You could do this.
00:01:04
If you watch very closely--
watch this.
00:01:06
As you tip it like this,
the water comes out.
00:01:09
The air comes in.
00:01:10
The water comes out.
00:01:11
The air comes in.
00:01:12
That flow is pretty good.
00:01:13
The problem is it's
not very fast.
00:01:15
Water comes out.
00:01:16
The air comes in.
00:01:17
And then you just get mad,
and you just do this.
00:01:19
But still, you're limited by
the fact that it exchanges.
00:01:21
You almost want the air to come
in here and the water to
00:01:25
And I've got a solution
for that, as well.
00:01:27
Get yourself a drill.
