– [Ximena] Hi. – [Roxanna] We’re Rainy Day Dreamers. – [Parris] And we’re back
with the super popular Wack-a-Pack Valentine’s. Today, we’re actually gonna actually open ’em up, find out how they work with the help of Presley
from Act Out Games. ♫ Rainy Day Dreamers ♫ Rainy Day Dreamers ♫ – Wack-A-Pack Valentine’s. A viewer told us about this. One of the coolest things ever. These Valentine’s start out in this little teabag kind of envelope. When you smack ’em, a chemical reaction happens and you get an inflated balloon. It’s a lot of fun, but how does it work? A few days ago, we tried out these
Wack-A-Pack Valentine’s, thought they were a lot of fun, But what we really wonder now is… – What makes the Wack-A-Pack so Pop-ular? – And so, before we try to
open up these Wack-A-Packs, to see if it really is safe, we wanted to call in an
expert on scientific things, so our friend Presley
over at Act Out Games, knows about this stuff, there’s lots of science experiments on their channels, so we’ve done a video call with them. Let’s take a look. – [Brian] Hi guys. – [Roxannna and Ximena] Hi. – It’s awesome to be talking to you. – [Parris] Yeah, you too. So, did you find some of these Wack-A-Packs in stores near you? Oh you got ’em. – We got quite a lot.
– [Parris] Great! – [Presley] actually,
we got like 50 packs. – So we did some of these,
had a lot of fun with them and we really wanted to
know what’s going on inside. We were about to cut ’em
open, and then we thought well, the way they pop,
maybe that’s not a good idea. So, do you think it’s
okay if we cut these open? – Yeah, it’s okay to open these things. It’s not going to kill you or anything. (laughs) It’s fine. – Yeah, you do need to be very careful… – [Parris] It’s not fireworks inside, or anything like that? – It’s not gunpowder.
– [Presley] No gunpowder. – [Brian] (laughs) There’s a
little packet of fluid in there that you can feel, kinda that hard pellet. You just wanna be sure you don’t cut, you just don’t wanna cut that when you cut it open. – [Parris] Oh, okay.
– [Brian] So, actually… if you cut… – [Parris] Do we need eye protection? – It’s not a bad idea, certainly. Never a bad idea
– [Parris] Okay. – [Brian] when you’re dealing with these kinds of chemical reactions. – Eye protection time. Ximena has the ongoing eye protection. Everybody. – Can I cut these open? – Sure. Now, just be careful of
cutting the packs, right? – Got it. – Yeah, so if you cut right along the edge of this outer envelope, kinda where the To and the From are, If you just
– [Parris] Along the edge. – [Brian] slice pretty thinly… – [Parris] Okay. – You should be able
to take the balloon out before you’ve cut the balloon. – Think we just tear it once
we’ve started it, right? – Careful. – Now don’t pop on me, okay. Oh, cool, that’s what it
looks like inside, yeah. – [Brian] There’s the
balloon that’s gonna inflate. – That’s right. – Can I cut the balloon? – Not yet. We haven’t gotten to that point, yet. Okay. – [Brian] Feel that little
liquid packet in there. – [Parris] You feel a
liquid package inside? – Yeah, something. – You can feel that little
liquid packet in there. Just cut on the other side. – [Paris] Is that in glass or plastic… – It’s plastic. It’s almost like saran wrap. It’s a little plastic wrap, yeah. – [Parris] Okay.
– [Brian] But it’s really, it’s tight and kinda
swollen, so when you hit it it pops. But if you just cut across the other side. And be careful because the balloon’s actually full of baking
soda, and it’s just loose. – [Parris] Oh. – So when you get in there,
you’ll see all that baking soda. – [Parris] Loose baking
soda, see some in there. – Oh, hi baking soda. – Loose baking soda, let’s see if you can see some in there
– [Ximena] Oh yeah, something spilled out already. – [Parris] Okay. – It looks powdery in there. Oh, I see it! I see it. – The baking soda, or the capsule? – The baking soda, I think. – Got both. – See, it came out on my finger. – Oh yeah, so this is just plain baking soda, perfectly safe, right? Oh, there’s the packet. So that’s what we’re looking for? Well this is simple. For what amazing stuff it does, this is so simple. – Very simple. Very simple. And so what’s in there (mumbles)? – In here is citric acid. – That’s right, citric acid and water is all that’s in that packet. – By the way, that’s kinda
– [Parris] Citric acid, like – [Presley] lemon juice
– [Parris] vitamin C? – That’s exactly right, yep.
– [Presley] Yes. – [Brian] So you could actually do this just as easily with lemon juice. – Yes, lemon juice. This is a [car-bo-nit]. – Carbonate.
– [Presley] Carbonate. – Carbonate. – So you have any kind of an
acid, and any kind of a carbonate, when they mix together, what do they make? – They make a neutralized… – Yeah, they neutralize each other. Then what are the byproducts? – They make salt, water, and… If you’re using a carbonate,
then also carbon dioxide. – Carbon dioxide. – So the whacking part involves basically breaking this little bag? That’s really all that does
is break the bag of liquid? – [Brian] That’s all… – Ahh. We thought it was some complicated
thing going on in there, but all you’re doing is breaking a bag, the stuff leaks out, hits
the powder, and then… Now, carbonation is like in soda, right? The bubbles? – It makes carbon dioxide gas, so when you have one of
these that’s completely full, it’s just full of carbon dioxide gas. – It is the volcano that you make. In fact, back there we have a kit that – [Brian] We do.
– [Presley] makes the volcano. So it’s a volcano, you put in the vinegar, you put in the baking soda you get boom!
– [Brian] Anyone who’s ever made a vinegar and baking soda volcano for a high school or a
school science project did exactly this same thing. What we thought we might do, though, is we got a little test tube.
– [Parris] Yes, okay. – We thought we might
just take the ingredients out of here, and pour
them in this test tube so you can watch them react and see what’s actually happening. – But what is this crystal.
– [Brian] Not yet. Yeah don’t do that. – I don’t know what it
is, but it looks cool. – Let’s pour the baking soda in. There it goes.
– [Presley] That startled me. – Oh yeah, yeah. – [Brian] That’s exactly what’s happening. – So I thought it was gonna bubble and overflow the test tube, but it’s not that strong of a reaction. – Yeah we’ve got one, so I did one with a vinegar, so I’ve got a little test tube here that’s got some vinegar in it. So that’s a little bit of a stronger acid, and so Presley’s gonna scoop
a little baking soda in here. – Well, that’s not a little, that’s… – [Parris] Okay.
– [Brian] Go ahead. – [Presley] Woo! Fizzies. – And so here, you can see…
– [Presley] Oh, gosh, that’s a lot of fizzies. – Oh, there it goes. – [Girls] Ooo!
– [Parris] Whoa! – [Ximena] Woo. – [Parris] Yeah. That’s what we like, big reactions. – Okay, we made a replica of it where there is a little,
gimme my saran pack. It’s vinegar wrapped in saran wrap. – Yep. – And then
– [Parris] Okay. – [Presley] loose baking
soda in the balloon, so it’s basically one of these except off-hand… (grunting) – Here, lemme just smash it. Oh, you did it.
– [Presley] Oh, yay I did it. – [Brian] So it’s hard to see it growing, but it’s doing exactly the same thing. – [Parris] Oh yeah.
– [Roxanna] Oh. – [Brian] Inflating the balloon, and shaking it up a little bit, and (audio unclear on call). The other thing that
it does that’s similar is the balloon is very cold. – We noticed that, yeah. – It’s an endothermic reaction which means it absorbs heat. So all you’re doing
when you punches these, you’re breaking the bag, and then… – Yeah, you’re just
breaking that little packet, I mean it’s…
– [Presley] And you made me hold it while it was blowing up, so when it popped open, I screamed. (Brian laughing) – Well the fact that it got cold, too, and it’s really cold, very fast, it seems like some major chemical thing is going on inside, so
that’s why we thought it was a really… But, of course they sell it for kids. How could it be a really
serious, dangerous thing, they wouldn’t give it to five-year-olds to do in their classroom. But it just seemed like
it had a lot of power because it was so cold. – And it’s depending on
what acid you’re using and what base you’re using is what salt is actually produced. – But it’s a salt and water
– [Presley] But if you were to drink that, then it would
just taste like salt water. – Meh, no, not all salt taste like salt. Don’t drink it (laughs). – Yeah, don’t drink that. If you were to… – Yeah, we weren’t that
dedicated to the project to try and drink the stuff,
but thanks for the suggestion. Right, so this is, when it puffs up, that’s pure carbon
dioxide that’s in there? – Pure carbon dioxide gas.
– [Presley] Dioxide. – [Brian] That’s exactly right. That’s all that’s inside of it. So you can actually take it out, and one of the things we were
thinking about playing with and trying to do, is
take a couple of these, and leech out the carbon dioxide. If you get carbon dioxide in a container, you can pour it on a candle
and put a candle out. – Oh, I remember that from high
school science class, yeah. That’s cool stuff. There’s a lot you can do with
this little 25-cent thing, that’s really amazing. It’s fun and interesting. – And it’s super, like this is the way if you watch our videos where
we do our science stuff, like this is exactly how
science happens in our house. We home-school Presley,
we do a lot of science, and it’s this. This is a super cool, clever little thing that if Presley is willing to just ask, “How does that work?” That’s all I want her to ever do. What’s going on in there? And then we can make it fun and we can tear things up, and we can make our own copies of it, and we can do all kinds of things, and Presley can learn about the chemistry that’s happening inside. – And I could be having fun. – Like you said, for a quarter. – That’s the key is
gettin’ the motivation, so yeah, if it’s a video game it’s good, if it’s sayin’ “How in the
world does this thing work?” That’s really what you
need is the motivation. From there, you just need somebody around who can explain it. So we appreciate you guys takin’ the time to explain this to us,
resolving the mystery. ‘Cause we were a little afraid. – Awesome, very happy to help, it’s super cool. Yeah, Presley? – Yeah, so all popping,
can I pop this one? – Yeah, go ahead and pop one. – So all this is, oh God I’m holding it! All that is,
(Brian laughing) is breaking a bag, you’re breaking a bag, and then you get a balloon. – And you’re going to be doing some more testing of these, and
trying out some other things is that right? – Absolutely, so what
we’re gonna do today. we started bringing a little
bit of structure to the channel so we have days where
we do certain things, a couple of days a week, and so Science Sunday is
one of our favorite days. Gonna be a more in-depth look at what we just kinda went through. We’ll talk about, like
this one that we made, we’ll give some step-by, see
how big it’s getting now? – Oh my God, it’s huge. – We’ll give you some
step-by-step instructions on how to build your own, and we’ll talk a little bit more about how acids and bases react, and how it works. So just a little bit more
detailed science explanation of what’s going on. That’ll be our Sunday video. – That’s great. We will link to that here,
up above Ximena’s head, and we’ll also put a link to
that down below this video. Go check out their channel, Act Out Games, it’s a lot of fun, if you find this kind
of stuff interesting, you’ll really like their videos. – There’s science and there’s toys and there’s other random
stuff that happens. – Sometimes there’s science with toys. – Yay. – We built a Segway
for a Monster High doll a couple of days ago. Yeah, awesome, we really
appreciate it, guys. Thanks so much for taking some time and for seeking us out and asking about how it worked, we learned a ton ourselves while we were doing it. – That was so nice of
Presley and her father to take the time to come and explain all that to us.
– [Ximena] Really was. Yeah, a lot of fun, they
have a very fun channel. Please go check it out. Again, we’ll have a link
down below this video you can check out the
video they’re gonna do with an even more in-depth investigation and experiments with
these fun little things. Now this is Super Bowl Sunday, earlier today we had our
giant M&M challenge, yes. We’ll link to that up in the corner here, with a little letter i,
our M&M challenge video. So the Super Bowl’s
gonna be starting soon, we’ve gotta go watch some pregame show, get our chips and dip ready, right? – Yeah. – Let’s hope the Patriots
don’t see this, right? – Why? – Just think if the
Patriots tried something with the underinflated
balls, and the referee says “Hey, hey, let me see that ball!” And they just smack it, “Here ya go.” Fully inflated. We’ll be back Monday, after the big game, with another fun video. You can check back then, or
