STEVE SPANGLER: Ever notice there's

00:00:02

bubbles that don't pop?

00:00:05

Well, they do pop when they touch your skin.

00:00:08

Why don't they pop when they're on the carpet?

00:00:10

I think I've got some answers and some really cool things to

00:00:13

do with bubbles that you can try at home.

STEVE SPANGLER: I'm Steve Spangler, and I'm all about

00:00:20

making science fun.

00:00:22

For the last 20 years, I've been teaching ways to turn

00:00:25

ordinary science experiments into unforgettable learning

00:00:28

experiences.

00:00:29

I have an amazing team who will do whatever it takes to

00:00:31

affect the way people think about science.

00:00:34

And to do that, I live by one motto, "Make it big.

00:00:37

Do it right.

00:00:39

Give it class."

STEVE SPANGLER: Well, if we're going to talk about bubbles,

00:00:46

we need to start with bubble solution.

00:00:48

And contrary to popular belief, it's not as easy as

00:00:50

just taking soap and adding it to water.

00:00:54

It probably will give you bubbles, but not the kind

00:00:56

we're looking for.

00:00:57

Well, if we're going to make great bubble solution, you've

00:00:59

got to start with the right things.

00:01:00

First of all, clean glassware.

00:01:01

So I don't want to use something that's dirty.

00:01:03

I'm trying to keep this as pure as possible.

00:01:06

And clean water.

00:01:08

Now what makes clean water?

00:01:09

How about distilled water?

00:01:11

Eight ounces of distilled water, 240 milliliters.

00:01:14

And of course, that's just for the purist.

00:01:17

The minerals, or sometimes the things that are in regular tap

00:01:20

water, they say, can hinder the

00:01:21

formation of great bubbles.

00:01:23

Take it for what it's worth.

00:01:24

We're using distilled water for these bubbles.

00:01:27

Soap, dish soap.

00:01:29

Now we're not looking for anything other than the

00:01:31

cheapest generic kind of dish soap, Dawn,

00:01:34

Lemon Joy, any of those.

00:01:35

We just want stuff that doesn't have apple, lemon,

00:01:38

orchard scented, H1N1-killing.

00:01:41

You just want just good, generic soap.

00:01:44

Into our eight ounces, we're going to add a

00:01:47

tablespoon of soap.

00:01:49

For our metric people out there, we're adding about 15

00:01:52

milliliters of our Dawn dish soap to the 240
