STEVE SPANGLER: So today's
questions.
00:00:01
Who likes a lot of these lights
and these lights here
00:00:04
and some batteries and this
thing and some electrical tape
00:00:07
and a whole thing of super
strong magnets?
00:00:12
I'm Steve Spangler and I'm all
about making science fun.
00:00:15
For the last 20 years, I've
been teaching ways to turn
00:00:18
ordinary science experiments
into unforgettable learning
00:00:22
I have an amazing team who will
do whatever it takes to
00:00:24
affect the way people
think about science.
00:00:27
And to do that I live by one
motto, make it big, do it
00:00:31
right, give it class.
00:00:38
As a kid you probably had a
whole bunch of these Christmas
00:00:40
lights, you know the strand
that breaks, and somebody
00:00:43
throws them away and you
figured this out.
00:00:44
You figured that you could take
a pair of scissors-- no,
00:00:46
not while it's plugged in--
you could take a pair of
00:00:48
scissors, cut it, strip the
ends off and get something
00:00:51
that looks like this.
00:00:53
This now, was perfect to be able
to learn how to use and
00:00:57
So you'd find yourself a big
battery, because you needed to
00:01:00
have a good supply
of energy there.
00:01:02
Because you never wanted
to hook up just one.
00:01:04
You'd want to hook
up multiples.
00:01:05
So you'd hang onto this one.
00:01:06
And this one would hook up
and use alligator clips.
00:01:09
And, low and behold, if you
completed the circuit, it
00:01:13
looked like this.
00:01:14
You see, as a kid, I
was easily amused.
00:01:17
You could do parallel circuit
and series circuits and
00:01:19
switches and whatever else you
wanted to but, in short order,
00:01:24
LEDs gave way to all of
this material here.
00:01:28
And this, was the new battery
and bulbs unit.
00:01:31
LEDs, light emitting diodes.
00:01:33
They come in all these different
sizes and shapes and
00:01:36
colors, and they run off such
a small amount of energy.
00:01:38
This is a watch battery, so
instead of that huge one we
00:01:41
had before, now you just have
this small little battery.
00:01:44
In this state here, this will
last 30, maybe 40 days
00:01:48
constantly on, and this is the
basis of today's project.
00:01:52
It's amazing what you
can find online.
00:01:54
I want to show you how
to make a throwie.
00:01:56
A throwie is a device that was
invented back in 2005, by
00:02:00
Graffiti Research Lab.
00:02:02
The idea was this-- what if
you could make light in a
00:02:06
device that you could throw and
have it stick to a metal
00:02:10
object and literally, graffiti
the side of a bridge or a
