Changing dirty diapers is a daunting parenting task for all dads. in this episode of The Lab, Daddy Clay and Daddy Brad review four different diaper pails. These baby products can be helpful for parents looking to dispose of their baby's diaper. Which diaper pail does the best job in keeping the poop stink to a minimum? DadLabs ep. 4 The Lab.

Daddy Brad: Hello and welcome to the Dad Labs. Today we’re going to talk about design.

Daddy Clay: Let’s start out by talking about bad design. Human babies, for example, terrible design. Narrow hips for upright walking, baby has to be born with sort an undeveloped brain and as a consequence, it poops itself for the first 2 or 3 years of life. Terrible design.

Daddy Brad: And that leads to the problem of stinky diapers. And you know, there’s only one thing that smells worse than your kid’s poopy, stinky diapers.

Daddy Clay: And that’s another kid’s poopy, stinky diaper. I mean, have you ever noticed that other kids’ diapers smell ten times worse than your kid’s diaper?

Daddy Brad: Yeah, that’s true, but that’s not where I was going -.

Daddy Clay: And if you can change another kid’s diaper, I know you’re expected to change your own kid’s, that’s the hallmark of modern fatherhood, but if you can change another kid’s diaper, you’re my hero. You’re advanced.

Daddy Brad: Absolutely. But that’s not where I was going. Where I was going was the only thing that smells worse than one of your kid’s poopy, stinky diapers is a sack of your kid’s poopy, stinky diapers marinating in this swampy, fecal stew.

Daddy Clay: That’s disgusting.

Daddy Brad: And that leads us to the design problem.

Daddy Clay: Exactly. What do you do with a whole bunch of stinky diapers, poop catchers in a big group in your house so that the smell doesn’t invade the room and bleed into the walls and make it so you have to burn the house down before you have people for dinner?

Daddy Brad: Have you ever been over to a house and it smells a little like a nursing home on enema day?

Daddy Clay: No. So don’t let that happen to you. Today, to keep that happening to you, we’ve brought in a number of diaper pails and they’re full of disgusting, aging, poopy diapers. And we’re going to put these diaper pails to the test.

Daddy Brad: Today we’re going to do two tests. Dispose of one stinky, poopy diaper and then change a full bag of stinky, poopy diapers.

Daddy Clay: Okay, so we’ve got four diaper pails here that are loaded with putrid, poop-filled diapers and this is a representative sample but by no means exhaustive. You may have a really cool diaper pail that’s some high-tech gizmo that you love. If you do, please tell us about it. Right here. Drop us a comment. Or you could even send us an email with a review or even a video and we’ll post it right here at www.dadlabs.com.

Daddy Brad: Okay, daddy Clay, let’s test ‘em out. What we have here is the Safety First. Tell us the specs.

Daddy Clay: Well, first you’ve got to push the button to release the top and you can see there’s kind of a clamshell sphincter in there that’s supposed to hold the individual diaper separate from the larger receptacle in the bottom, so just drop the diaper in there and then quickly close that damn thing which should shoot the diaper down into the larger receptacle and it’s supposed to keep it from stinking. But, it doesn’t smell good.

Daddy Brad: No. Not good.

Daddy Clay: It’s not terrible. I mean, I’m not gagging.

Daddy Brad: I wouldn’t give it as a perfume.

Daddy Clay: Okay. So let’s go to the next one. This is Fisher Price. This has a similar sort of a mechanism, also a sphincter. What happens, is you open up this top and there’s a sort of iris-shaped sphincter that holds the bag in place and that’s supposed to completely separate the smell of the receptacle below…got a little echo putridness there…and then basically you open the sphincter and the diaper falls down and then you close the sphincter and that supposed to provide a perfect seal keeping the stench out of the room.

Daddy Brad: You can see down in there.

Daddy Clay: That smells bad. That stinks.

Daddy Brad: The next one is the Costco.

Daddy Clay: Okay, let’s just check the smell-reducing mechanism here. Woa! Look, it’s just a top. It’s just a top. Put it in there! Troy, this is yours right? I mean, this is your diaper pail?

Daddy Brad: Take the family out for a little steak dinner last night?

Daddy Clay: What are you feeding the children? What are feeding the children?

Daddy Brad: It won’t close!

Daddy Clay: That’s not right, dude. This is not right.

Daddy Brad: Okay. And then probably our most high-tech version is the Diaper Champ by Baby Trends. It’s got this thing like at the bank where you put your money in and it sucks it over to the teller. You just drop your diaper in there, and then do that, and then it’s down there, then you do this. Watch out, don’t get your finger or nose stuck in there.

Daddy Clay: I catch a little bit of ass.

Daddy Brad: It’s a little apricot.

Daddy Clay: It’s just like someone pulled back the diaper back a little bit to do a sniff test it. It’s not overpowering. And really now it’s gone. That’s pretty impressive.

Daddy Brad: Okay, well now that’s the disposal of one diaper. Now let’s do changing the bag. Ready?

Daddy Clay: Are we ready?

Daddy Brad: Yeah, I’m ready.

Daddy Clay: It smells so bad in here right now. That’s clearly the worst dad job that there is.

Daddy Brad: But you got to do it.

Daddy Clay: I’m going to do the rest of this bit, only breathing through my mouth. I hope you don’t mind.

Daddy Brad: It’s pretty bad. The deal is, poopy diapers, they really never get any better.

Daddy Clay: No. It’s a terrible situation because from the time your child is born until your child potty-trains, diapers only get worse. They get bigger, they get stinkier, they get stickier and they get worse.

Daddy Brad: There are spikes. Like when they start eating hot dogs.

Daddy Clay: Or the 18 month old sneaks off and goes to the refrigerator and eats a pound and a half of grapes and the next thing you know he’s blowing half-digested grape skins all in the car seat. But pretty much the trend is steady and it just gets worse.

Daddy Brad: Potty train! Come on potty train!

Daddy Clay: So we’ve tried four different diaper pails here. If you’ve got one that works really well for you, please let us know about it. Again, drop us a comment, let us know about the diaper pail that works for you. Send us a review or a video and we’ll post it here at www.dadlabs.com.
