[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.
