- Hey, guys.

My name is C.J.

I am a Play Facilitator here at the Scott Family Amazeum.

And today, I'm gonna take you through one of my favorite Hershey's Lab experiments.

It's called, Fizzy Fun.

And we're gonna learn about acid-base chemical reactions.

So, the first thing that I'm going to do is crush up all of my Ice Breakers.

(upbeat instrumental music) (hammer tapping) So, it's really important that we crush up our Ice Breakers.

It's going to give them more surface area and give us a better reaction later because more of them will be able to dissolve.

So, because we can't do a chemical reaction in a plastic bag, I'm going to put them all into test tubes.

So, I have four of them.

Each test tube is labeled one, two, three or four.

And that's just so we can keep track of all of our stuff.

Here we go.

So, test your number one.

We're gonna put bag number one into.

(ice breakers sliding) And it all gets a little messy, totally fine.

The more mess, the better.

Test tube number two.

And I want to get as much in there as I can because the Ice Breaker is what's gonna to determine how our reaction is going to go?

How big it's gonna to be?

Number three.

(ice breakers sliding) And then one more, number four.

(bag opening) (ice breakers sliding) Cool.

Today, we are going to dissolve our Ice Breakers in water and that's because water is really, really good at dissolving things.

It'll break apart more compounds than almost any other liquid on the planet.

And that's because water is polar.

You can think about it kind of like a magnet.

One side is really positive and the other side is really negative and so it attracts stuff to it and therefore it can dissolve more.

So, my first two tubes are going to get cold water.

So, I'm gonna pour this in.

Doop.

(water splashing) Doop.

It's okay, if we pour a little bit over.

And the second two tubes are going to get warm water.

And we're gonna see if cold water or warm water makes any difference at all.

(water splashing) So, I'm just gonna pour in just enough.

Boom.

And then we're gonna to do the same thing.

So, water's going to go in.

One.

And two.

And now, so we don't have any giant spills, I'm gonna put caps on all of our test tubes.

Now it's time to dissolve our Ice Breakers.

To do that, we're gonna shake them really, really, really good.

And there's a lot of different ways you can do it.

You can just go ham and shake 'em kinda like the Maracas or you could be a cool scientist and invert them, like they would in a real lab.

Either way, it's okay.

As long as we shake them for about 20 seconds.

(ice breakers shaking) So, now I'm going to line my tubes up, one, two, three and four, and we're gonna do my favorite part of the reaction and that is adding baking soda to it.

So, we're gonna start with tube number one and I'm gonna take a full teaspoon of baking soda and stick it right into that tube.

You can also use a funnel, sometimes that helps.

And if you guys can see, all of that baking soda just ends up right at the bottom.

And actually, if you wanted to, you could pull it out of the tube and dry it off and use it in a cake later.

It's perfectly the same, nothing happened, there's no change.

Now on to tubes two, three and four.

I will use a funnel this time.

So, tube number two.

(spoon clanks) Whoa!

We got lots of bubbles.

So, because tube number one didn't have a reaction, I don't think tube number three will because we determined that they smelled the same.

So, even though it has warm water, I don't think it's gonna react but we're gonna try it anyway.

Big scoop.

A little tap-tap.

(funnel tapping) Boom!

There's still baking soda all around the bottom.

Now, we're gonna move on to tube number four.

So, I'm gonna place on our funnel and make sure we get a nice big teaspoon of baking soda into tube number four.

Whoa!

And we did, we got a much bigger reaction.

So, when we dissolve it in water, the water became very acidic.

And when we added the base of baking soda to it, we had a very special chemical reaction called a neutralization reaction, where the acid and base basically canceled each other out.

And to do that, you have to let stuff off and that stuff is the bubbles we see.

It's actually carbon dioxide.
