STEVE SPANGLER: So I know what
you're thinking, how could it
00:00:02
be November, in Colorado, and
there's still leaves on the
00:00:05
trees, and I'm dressed
like this?
00:00:07
More importantly, what's up with
the potato and the straw?
00:00:09
I'm going to tell you what.
00:00:10
I'm going to take this straw,
and I'm going to jam it
00:00:12
through this potato, and you're
going to like it, but
00:00:14
not before you watch this.
00:00:16
I'm Steve Spangler, and I'm all
about making science fun.
00:00:19
For the last 20 years, I've
been teaching ways to turn
00:00:22
ordinary science experiments
into unforgettable learning
00:00:26
I have an amazing team who will
do whatever it takes to
00:00:29
affect the way people
think about science.
00:00:31
And to do that, I live by one
motto, make it big, do it
00:00:35
right, give it class.
00:00:42
It's the first science
00:00:43
experiment that I ever learned.
00:00:44
It was actually in
kindergarten.
00:00:46
I had a kindergarten teacher
who had a whole thing of
00:00:48
potatoes sitting there, and
a whole thing of straws.
00:00:50
And the challenge was, she said
boys and girls, I want
00:00:52
you to take that-- because she
always said boys and girls--
00:00:55
take this straw and jam
it through the potato.
00:00:57
And do that a whole bunch of
times, and when you're done,
00:00:59
It'll be a porcupine.
00:01:00
We'll put eyes on it,
and that's your
00:01:02
little take-home surprise.
00:01:03
And she didn't even have to
finish those words, and
00:01:05
there's 14 boys trying to jam
a straw through a potato.
00:01:09
If you can't see, it doesn't
work so well.
00:01:12
If you try to jam a straw
through the potato, it doesn't
00:01:14
work because it crumbles.
00:01:15
Unless, you use what's
in the straw.
00:01:17
And what is inside the straw?
00:01:18
Yes, ladies and gentlemen,
it's called air.
00:01:21
So if you put your thumb over
the end of the straw, you trap
00:01:24
And now, as you hold
onto it like this,
00:01:27
you just jam through.
00:01:28
And what I've learned
is that brown is the
00:01:30
potato, and pink is me.
00:01:32
So you have to practice where
you're going to jam, but it's
00:01:36
Here, watch this.
00:01:37
Straw through the potato.
00:01:40
See that air gives the straw
that rigid support, because
00:01:43
air takes up space.
