In this YouTube prank video, the host and his crew orchestrate an elaborate surprise for the host’s brother. While the brother (CJ) is busy covering a house with sticky notes, the crew fills his actual house with massive amounts of "elephant toothpaste" foam—an exothermic reaction using hydrogen peroxide—to create a chaotic, foam‑filled environment. They enlist Mark Rober, a known expert with two world records in elephant‑toothpaste demonstrations, to help scale the reaction, planning to use 14 drums (about 500 gallons) of foam, nearly double the existing world record. The narrative interweaves comedic banter, safety warnings, and logistical coordination among several participants (Karl, CJ, Brady, Frank, etc.). After the foam is unleashed and the brother discovers the mess, the prank culminates in gifting him a brand‑new house, with assurances that the original house will be repaired. The video blends high‑energy, informal commentary with a surprise‑gift twist, emphasizing spectacle, teamwork, and the thrill of breaking a record.
Chapters
Today we are filling my brother's house with elephant toothpaste and then we're gonna surprise him with a brand new house. And you might be wondering why. Well, I caught wind that my brother is covering Karl's house with sticky notes and I thought it'd be funny if while he did that, we filled his house with elephant toothpaste. Prank inception. If you take this and pour it in this, you get elephant toothpaste.
Oh my.
That is insane.
Look at it.
And that was hardly any. And if you take 1,000 times that, pull.
Oh my goodness. Are you sure?
Oh my goodness. You get this. And what you just saw is nothing compared to what we're going to do to my brother's house.
Dude, it might blow the roof off.
There's enough in these barrels to fill 5 houses. And my brother only has one. So we'll use a little less. And because we have so much elephant toothpaste, I had to bring in an expert.
That's me.
Do you mind moving, Karl?
I'm the expert. Oh my goodness.
Mark literally holds 2 world records with elephant toothpaste and has done multiple videos on it. This is my brother's house. Welcome in, everybody. This is Frank's room, his roommate. We're not gonna mess with that.
We are gonna mess with this.
Yes, we are gonna mess with this room.
Is that underwear on the fan? Oh, what the heck?
Uh, can you go outside real quick? Go grab Chris.
What's up?
Karl has no idea this house is currently being sticky nutted. And CJ thinks he's pranking Karl, but CJ's actually getting pranked. It's a lot to keep up with. As I keep saying, we will fill this entire house with elephant toothpaste. But first, we wanna test things in the bathroom. Let's do it.
You just pull it. Pull it. Oh gosh. Oh, I think so. Oh, I think so. Oh my gosh.
I turned around and I felt a wave of heat just engorged me. I'm so glad you turned around because I turned around when you did.
You guys violated the safety protocol. It's like, get far away.
When we actually fill his house, I'm going to be 30 houses away this time. Oh my gosh.
Oh, look at the ceiling.
Oh my goodness. And we're gonna do this to his entire house. House when he comes home. Not gonna lie, I've never been so scared of foam in my entire life. Now that we got that out the way, I gotta go check in on CJ. I need to check his progress on sticky noting Brady's house. Pause. You might be confused why I just said Brady's house is getting covered in sticky notes when it's obviously Karl's house. Well, to not spoil my brother's video, we couldn't tell Karl his house was being sticky noted, so Karl thinks we're covering Brady's house with sticky notes. Mark, I'm putting you in charge of the boys. I'm gonna go check on CJ.
I'll do my best.
All right, my brother has no idea we're parked here, and he's currently filming a video where he's gonna cover Carl's entire house with sticky notes! I can hear them talking inside. Future me, grab CJ's footage and see what they're talking about.
Uh, the sticky notes keep falling down and I'm running out of sticky notes. I need you to get some more.
Got it, I'll get you some sticky notes. All right Jake, here you go. Thanks CJ, appreciate it! Let's get out of here before our cover's blown. They're sticking note on the inside and they're saving this part— the outside for last.
All right, let's go do it! Do it! Go, go, go, move, move, move! Oh my God!
It pushed him!
TV! Leave you guys alone for like 2 minutes!
It's your fault you left us alone! We need supervision at all times!
Oh, look at this! It's going to be 20 times the amount of foam that you just saw in this room alone. I'm an expert, don't try this at home.
Oh, that didn't look worth it. That just didn't look worth it.
Go! Oh, I'm stuck!
Mark, what is this? It's Mark's fault he left us alone. I just got back from scouting out the sticky noted house. According to my calculations, he should be done sticky noting in under an hour. And when he pulls in that driveway, what do we want? We want his house to erupt in foam right when CJ pulls into his driveway we're gonna unleash all of the elephant foam! It's literally going to blow every door and window outta this house for 1 mile! I need 4 barrels in this room, 4 barrels in his room, 4 barrels in that room, put the other barrels wherever else they fit!
Woo!
This is insane just big and crazy and chaotic windows will be blown out! 1, 2, 3, 4... 5, 6, 7, 8, 9, 10, 11, 12, 13— 14 drums of elephant toothpaste. And let me remind you, this is what one drum looked like on its own. And we have 14 of these.
I washed my hands of this, all right?
If things go bad, it's all my fault. Thank you. Because I trusted Mark. What is the current elephant toothpaste world record?
About 290 gallons of hydrogen peroxide.
Okay, and we are using 500 today.
Yeah, you got to—
So we are almost doubling the current world record for elephant toothpaste in CJ's house.
That's right.
The world record toothpaste is almost ready. The second you get a phone call from me, don't even answer it. Let it rip.
Okay.
Let it rip. I will call you when we are ready. All right, let's go check out Brady's house. Brady lives on the other side of your neighborhood, Karl. So we're coming up on your house, right, Karl?
Oh no. Yeah, we are. I wonder why. Wait, why am I so dumb? What the fuck?
So this whole video, every—
Oh my God.
The plan has always been to sticky note your house and we are using Brady as a coverup.
Why did I not even see that? I really genuinely didn't see that. What the fuck? Karl! Karl! I hate you guys. I hate all of you. Both brothers.
I hate both brothers now. Not only did you get pranked on our channel, but you got pranked on his channel. Oh, hey.
You know you don't have to let them in, right? Yeah, you could just keep the door locked. They promised that, uh, they wouldn't do my room, and I was like, yeah, that's fine. Wait, they did my room? Yeah, that's not even how you spell it. You didn't even spell it right. What do you mean, look what I Ah! Ooh! Closet wizard strikes again! What? Can you guys all get out of my house? Please? We should leave now, huh? That's what I'm thinking about. I'm thinking about leaving now.
Oh, yeah, you're thinking about leaving?
Yeah, I'm thinking about leaving.
We're about to take your record. Sorry about that.
Yeah, I think windows will get broken.
Oh, windows will get broken? Oh my goodness. Sorry if we fill your yard with slime. We'll fix it. Is this legal?
Uh, I mean, it's fun.
I think that's good enough answer for me. Wait, where's your house? I don't think I've ever been to your house. It's right past all those cars.
Is this your house? Yeah.
Well, I just want to see it. I've never been to your house before.
You live here? Mhm.
All right, so 3, 2, 1.
3, 2, 1.
Oh my gosh, here it goes!
Oh my gosh! Oh my God! Oh my God! What'd you guys do to my house? Wait, who let you in the house?
Uh, you know, Frank. Oh my God, you spent the day covering Karl's house with sticky notes to surprise Carl. And while you were doing that, we were filling your house with elephant toothpaste waiting for you to come home.
Oh yeah, should we throw a rock through this front window? Oh, hey, open it. Oh, run, CJ! Run, CJ!
No, Chris, I gave you permission to break my front window.
Can Mark Rober help?
Yeah. Yes, you can also help. Thank you, CJ. I love you.
I've always wanted to do this. Oh, it went through.
Chris, you want to open this door for us, please? And thank you.
Okay, you got it. I didn't mean to set you up. I didn't mean to set you up like that.
Oh my gosh, that was so hot. Oh, it is hot. Oh, whoa, that's steamy.
Hey, let me in. Go, go! Oh shoot. Whoa, there we go, dude. I want to run through there so badly.
How did you guys actually do this?
Mark Rober right there.
Yeah, Mark Rober. We got your roommate's permission. We brought down Mark Rober and we took everything important out of the house. So what are you buying Carl since you stick a note in his house?
Ah! I'm kidding. I mean, I did leave some of my stuff.
I'm kidding. The sticky notes can easily come off, but this obviously is a lot more damaging, which is why CJ, we bought you a brand new house.
Really?
Yep.
Really? Where's it at?
This is CJ's brand new house. Come on in. Check it out. Check it out.
Oh my goodness.
I still cannot believe that this is mine.
This is my new house.
Do you like this house? Because I could get you a different one if you're not happy. No, I actually like this house.
It's actually great.
And just to clarify, I have a team working around the clock to fix his old house. Don't worry, we're not gonna screw him over. I wonder what that means.
