Summary: Elephant toothpaste (aka slime foam) has sort been done so many times I wanted to do it really big. We did a ton of testing.

This is the brand new guinness world record largest ever elephant toothpaste, film experiment in today's video, which is partially sponsored by lastpass, i'm going to walk you through everything we had to go through to get to this point, as well as some really cool side discoveries. We made in our hundreds of hours of testing along the way the main ingredient for elephant's toothpaste is hydrogen peroxide, it's the same stuff. You pour on a scrape to disinfect it. The thing is the bonds that hold the hydrogen and oxygen together are pretty weak.

So if we poured some of this in here and just left it for a while, it would keep releasing oxygen and eventually you'd be left with just water. However, if you add a catalyst like potassium iodide, you can make that slow process happen almost instantly. So that's cool, but we can make it way more impressive if we add one key ingredient. So so, if we pour this in and then do everything else the same now when the oxygen is released, the soap captures it creating bubbles and foam and then finally, if you do all that again only now you add food coloring and use a flask that tapers, Like this, you can focus the expansion of foam, so it looks maximum awesome.

So, in order to fill a pool with this stuff, i first got together with some friends and we spent literally hundreds of hours for a few weeks running experiments to calculate the best raw ingredient. Combinations, in addition to brainstorming other cool things we might do with it, and so before we attempted to shatter the current world record. We had an end of summer party with my son and a bunch of family friends where we wanted to share with them the coolest side, discoveries from our research, but first in true end of summer fashion, we had to knock out some slip and slide kickball. I plan to kick things off by attacking them with an elephant toothpaste gun we made as revenge for when a bunch of these same kids, ambushed me on a recent beach trip and then offered me some cookies, which were just six massive cockroaches and i hate cockroaches.

However, as part of our testing, we discovered the reaction is highly exothermic, which means it generates heat as a byproduct. If you watch it, infrared you'll see the temperature of the foam right after the reaction can reach almost 200 degrees fahrenheit. So because i'm nice, i shelved my revenge plans and just demonstrated what would have been their fate and told them to sit and watch at a safe distance and they listened sort of, and so now that we have their attention. It was show time this one's called the melted unicorn.

You might recognize bob flugfelder here, aka science, bob he's been on jimmy kimmel live 11 more times than i have, and i invited him out to join me for a very specific reason which i will address in a bit and so with the success of the science. Show behind us it was now time for phase two, so we are here standing in an empty swimming pool about to try and break the world record for elephants, toothpaste. You want to tell the good people who owns the current world record bob. I do you want to tell the good people who's about to not own the world record bob.

Pretty confident. Aren't you no i'm your engineer, but if everything goes well, we're hoping to quadruple the amount of the current record which you hold, i'm not sure how much of like the trees and neighborhood we're gon na cover in the process. Only time will tell and chemistry which i don't understand, but we'll see what we can come up with. We wanted the phone to be safe to play in afterwards, so we used ordinary baking yeast as our catalyst.

We could have bought yeast in big buckets, but it turned out. It was cheaper to get them in one pound bags. The only downside to that is that you have to cut open 180 one pound bags of yeast, but that's why we have science bob come on out. They said it'll be fun.

They said this is an emergency tarp system. So if we did our math right, it shouldn't overflow in the case that it does. We have these tarps here to contain all of the foam from not going everywhere in the yard. We hope for the best plan for the worst.

We built these three frames for the tarps that would contain the catalyst yeast solution. So when it was time to fill the pool, we could just cut the tarps and it would pour out the same way. We cut the tarp when we added the bigger orbeez and kevin. It's go time.

Baby, we're probably like seven minutes out got a bunch of kids inside, are just raring to get out the challenge here is this water's warm? We didn't build these containers big enough. So this will start rising, so it's sort of a race against the clock before it starts overflowing. We still have to add the soap and then we have to add the food coloring. Oh, this looks terrifying as i stab this bloody thing.

I think i'm about to get demonetized. Okay, now we're adding the soap. This is what will actually make the bubbles. Soap isn't part of the reaction.

Two more soap buckets, oh as you can see that bucket's going up real, quick. So, after a few final touches, we were ready to go three two one. Now, before we get the tarps, i want to point out: i'm not a chemist with the physics and engineering problem, i'm way more comfortable understanding the parameters and getting closer to the final solution off the bat. But chemistry is just little molecules i can't see, and it feels a lot like trial and error without any guarantee it will actually scale up.

Predictably, this was feeling like the nightmare of the jello pool all over again. To get to this point. We had ran over 150 tests, sometimes at great peril to that which we hold dear, and so once again, if this was a total failure, it wouldn't be from lack of effort. Having said all that here, she is two one go, so the good news is we broke the record.

The bad news is we're kind of overachievers uh-oh. It's coming up the great tsunami. Hey hold this okay stand back off the tarp. Oh, we need to grab him stand back, hold this up, bob okay.

So while we pushed all the foam back into the pool that gave it some time to cool down, so we could actually touch it. The drone was super cool because not only did it make the foam look like an alien cocoon, but you could see it travel in infrared because it would expose the much hotter lower layers of foam as it flew around. What do you guys think? Do you think this is going to float? No all right here we go after all our tests, we perfected the chemistry for this stuff. So if you want to make a home version, you can play with check out science bob's website i'll leave a link in the video description, all right, bob sorry, you're, looking at an obsolete piece of material there i had it for over a year, you did have It for every year, but all good things must come to an end.

I was mad but darn. It was a lot of fun. That was a lot of fun and i have good news because you are still the world record holder, i'm putting you on there with me: buddy nerd hug, you.

    ๐Ÿ™‹โ€โ™‚๏ธYou all see the video on the screen
    simple but the truth behind this is
    that on the channels thousands of
    people work then go or one they
    are able to make videos so that their
    family runs that's why all of you have
    one click of these people you must
    click that life can change,Thanks๐Ÿ‘
