Acid vs Lava: Ultimate Showdown!
45sThe high-stakes face-off between acid and lava with exciting visuals and a car prize creates immediate intrigue and clickability.
▶ Play ClipIn this video, Mark Rober hosts a scientific competition between three YouTube scientists—NileRed, Kevin (the Backyard Scientist), and himself—to determine which destructive liquid, acid or lava, is more effective at destroying various objects, including a turkey leg, an iPad, ice, baseball bats, and ultimately a car. The video combines entertainment with educational demonstrations of chemical and physical reactions.
Mark Rober introduces a scientific face-off between acid and lava, with NileRed (acid) and Kevin (lava) as contestants. They will test destruction on a turkey leg, iPad, ice, and a car.
William Osmond is brought in as referee. The competition consists of multiple rounds with different objects.
Lava chars the outside of the turkey leg but doesn't fully destroy it. Acid also fails to completely dissolve it. The round is inconclusive.
Mark's wild card was a school of 50 piranhas, but they are illegal to own as pets in California, so the plan is abandoned.
Lava and acid are tested on an iPad. Lava melts it partially, but acid (via NileRed) destroys it more effectively by submerging it in acid, which stops the video playback instantly.
NileRed explains that certain acids can dissolve metals, but not all. He demonstrates with gallium spoon and discusses acid strength.
Lava melts through ice quickly, creating tunnels. Acid is less effective, only breaking through one layer. Kevin's lava wins this round.
Acid and lava are tested on plastic toys. Acid fails to react due to plastic's stable chemical structure, while lava melts them easily.
Mark introduces a 50-ton excavator as his wild card for the final car destruction round.
Kevin uses a laser to cut through a baseball bat, winning the round. Acid fails to dissolve the bat effectively.
NileRed tests acid on a 1.2-carat diamond. The acid does not dissolve the diamond, demonstrating diamond's chemical resistance.
The final round involves destroying a car. Kevin uses lava, NileRed uses aqua regia (nitric + hydrochloric acid), and Mark uses the excavator.
Mark's excavator crushes the car completely, but the engine still runs. Kevin's lava fails to stop the engine. NileRed's acid damages the engine but the car still runs.
Kevin is declared the winner because his lava caused the most visible destruction, though the car still ran. Mark gives Kevin the car as a prize.
Mark promotes his Roblox game 'Build a Rocket' on Crunch Labs, where players can build rockets and explore space.
The competition ends with Kevin's lava being declared the winner due to its dramatic destructive power, though both acid and lava had their strengths. The video emphasizes the fun of scientific experimentation and promotes Mark's Crunch Labs game.
"The title accurately reflects the content: a direct comparison of acid vs lava destroying various objects, including a car."
What is aqua regia?
A mixture of nitric acid and hydrochloric acid that can dissolve gold and platinum.

12:37Excavator Destruction
Mark uses a 50-ton excavator to crush the car, showcasing mechanical destruction.
16:03[00:00] Well, to answer that question, (upbeat symphony music) in a bit of a scientific face off including a turkey leg, an iPad, slabs of ice,
[00:14] and finally an actual functioning car. I've invited out YouTube's foremost expert - With the buttery smooth voice
[00:29] - [NileRed] Oh no. will be YouTube's very own lava king. - You didn't see the fire.
[00:42] - Yeah, it was pretty cool. - Kevin, the backyard scientist. I'm just gonna stand by and watch.
[00:55] I'll be testing a wild card factor of destruction my wild card factor of destruction And then for the baseball bat,
[01:08] (flame whooshing) And the nerd trash talk (upbeat funky music) - I think acid could.
[01:20] Oh and I do wanna mention winner of today's competition gets a car. - Yeah.
[01:32] - [Mark] Someone you might recognize Mr. William Osmond. I made him be referee.
[01:46] spare referee shorts on hand, starting first with (tense music) - Here we go.
[01:59] - Oh yeah, yeah! (Mark laughing) - [Lava King] Burn!
[02:11] - Boom! we cracked open the crucible (hammer thudding) And while it definitely charred the outside,
[02:26] - It's fine. definitely all gave it a taste. - Which meant it was time
[02:39] (upbeat techno music) considering what our own it was terrifyingly efficient.
[02:52] and what's the dark stuff here? - How do we know you didn't just - And so after a fruitless search for foul play,
[03:06] it would come down to my brilliant a school of 50 pirahnas (piranas rustling) that took less than a minute (bone cracking)
[03:18] My plan however was ruined they're illegal to own as pets. while smaller, with an enough of 'em,
[03:32] - Oh! It's instant! - No way. when I raised it up, it was basically untouched, but frankly for the state of California.
[03:47] - I definitely never said that. sending us into round two with the iPad. and that hunger only intensified
[03:59] - Right on my face. (flame whooshing) (upbeat synth music)
[04:12] - Oh, now we can't see if it's playing. - No more, more, more. - That's enough. was it enough to stop the iPad from playing?
[04:26] Nigel was up next. (upbeat funky music) he slipped the iPad into eight - The video turned off instantly.
[04:40] - It was time to see what acid could do. Give it time. - Boo! some kind of small reaction
[04:55] which makes us the perfect opportunity that can immediately dissolve all metals. I've seen really popular videos like this online
[05:08] However, I would offer the counterpoint dip his fingers in the acid later in the video And that spoon is actually made from gallium,
[05:21] Now, certain acids can dissolve certain metals, for chunks of metal like this. Normally this fires tennis balls.
[05:35] at like 200 miles an hour. The real question is, how's my aim? Pretty good as it turns out.
[05:49] - Oh my! it still had enough kinetic energy - It almost split the whole thing in half too.
[06:02] Let's see your acid do that, Nigel. - It's pretty cool. - Okay. as we headed into the ice round.
[06:14] And lava came right out of the gate sizzling hot. No! you didn't make it through one.
[06:27] - Admittedly, the bubbles were pretty cool. - Look, I made lava spaghetti. (lava sizzling) as only breaking through one of the 12 layers.
[06:40] was too little too late, Oh wow. Wow.
[06:54] - It just kept breaking through each layer that bored a hole through the ice like a laser. - One more. Why am I rooting for you?
[07:08] which meant my wild card would have Gentlemen, my approach here is a (flame thrower whirring)
[07:22] (Mark screaming) - All right a good engineer always (ice shattering)
[07:36] from the Acme Corporation. - Not only finished off my ice, - Yeah. - Technical foul.
[07:49] But with further evidence of referee bias. The win-win to Nigel, And this one for sure had
[08:03] - Three, two, one. - Which definitely makes Kevin, backyard Sid. - Oh no, for the school.
[08:16] Oh, no Stretch scratched. I got it. (extinguisher whooshing) - Oh Stretch.
[08:31] - So with an identical set of toys ready to go. - Start with some sulfuric. As the forecast called for acid rain.
[08:44] - And after a combination of several acids, were mildly inconvenienced at best. - And the lack of reaction with the plastic toys
[08:59] highly stable chemical structures, it takes them so long to degrade in a landfill, stored in plastic containers.
[09:13] it was time for the Mark Rober Wild Card. America! (eagle screeching)
[09:25] (heavy metal rock music) (friends laughing) this makes a great time to mention that.
[09:38] because you can now visit Crunch Labs 'Cause the game's called, where you build fully customizable rockets
[09:50] the evil fat tail (Phat tail cackling) this project for over a year. as a trick to teach you science."
[10:04] I'm just trying to make a really fun free game. in the process, well that's not my fault." of Phat Gus before the end of the year
[10:18] to CrunchLabs in real life for a day So visit CrunchLabs.com/Roblox "Build a Rocket," on Roblox for free
[10:33] building rockets with your friends. (heavy metal rock music) (friends cheering) - No, this very unsportsmanlike.
[10:53] - Yeah! but it still felt cool. Who would've thought the
[11:05] This one a hundred percent goes to Kevin. - Definitely. I think metal, - Kevin's lava quickly melted away
[11:18] Oh, that's a nice layer, Kevin. So it was up to Nigel's acid to top that. (metal clinking)
[11:31] And I'm actually gonna go with the wood bat. 'Cause my contraption just happens to be which you may or may not recognize
[11:44] And it's also how he knew a fact that I didn't, - This 2000 watt laser is actually So we ran a test.
[11:58] (can clinking) Wow! Judge, can I? - No. Regardless, I pressed onward.
[12:11] That's pretty strong. And this was honestly the closest thing - Oh my God.
[12:23] He's like two thirds through, I think. Look at that pure destruction. And Kevin's laser did it. (friends laughing)
[12:37] I couldn't outright win this competition. 1.2 karats right here. - Ready?
[12:51] in sort of a lava sandwich. chiseled away the actual obsidian. 1.2 karat diamond versus acid.
[13:06] (water plopping) It's time for the wild card to kick it old school I'm just gonna smash the crud out of this.
[13:20] With the W heading into the final challenge in (hammer thudding) - Did you miss again, Mark?
[13:34] Are you kidding me? You have two points. And I've got one.
[13:46] Which set up the perfect finale showdown - Where's Mark? (upbeat country music)
[14:01] - That's probably Mark. Yeah! - Dude, why'd you park so close?
[14:13] - The rules were simple. (upbeat hip hop music) will get two points and win it all. - I have a propane burner here
[14:26] I'm gonna start adding nitric acid Aqua regia start the engine. It'll just start tearing all the metal apart
[14:40] from a safe distance. - Oh. - Hey! Wow more uninvited science YouTubers
[14:52] And since they were already here, questionably sized referee uniforms, with the service of the metal,
[15:04] We call this corrosion. increasing the concentration of the acid, that just means the molecules
[15:18] will make contact with the metal as a last ditch effort, Nigel did both. (slingshot clicking)
[15:33] (glass clinking) (acid sizzling) - I like the slow release. (glass shattering) - That is terrifying. - That is.
[15:48] - Now for the verdict. Honda makes a good car. (hands clapping) (air whooshing)
[16:03] - I prepared to release the final mega wild card in the form of a 50 ton excavator. Oh. (excavator beeping)
[16:17] was to use tools of scientific inquiry of interactions in the natural world. of operating a 50 ton excavator.
[16:32] - Yeah! (car shattering) Yeah! (upbeat heavy metal music)
[16:46] - Oh no. - Oh no. - Yeah! (car crashing) (glass shattering)
[17:01] And with my finishing move. - I am very precariously balanced. the engine was definitely not (triumphant horn music)
[17:16] - The machine was impressive. - Yeah. - So for the grand finale lava. (friends cheering)
[17:31] (lava sizzling) With the lava poured, it was time for Kevin's escape.
[17:46] Oh, it stopped already no. - Wow, all it took was four gallons of lava. Oh wow.
[18:01] (extinguisher whooshing) So now the judges just had Don't make me regret ever even having
[18:13] - Okay, so. - Nigel's car still runs perfectly. - And Mark, how long did Mark take?
[18:25] - You counted for when I start moving? - Kevin! - Kevin! And as a reward for a fight well fought,
[18:39] Congratulations. I'm basically Oprah. this Crunch Labs Roblox game for over a year.
