World's Largest Elephant Toothpaste Experiment

this is the brand new Guinness World Record largest ever elephant toothpaste comb experiment in today's video which is partially sponsored by LastPass I'm gonna walk you through everything we have to go through to get to this point as well as some really cool side discoveries who 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 it's great to disinfect it the thing is the bonds the 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 could make that slow process happen almost instantly so that's cool but we can make it way more impressive if we had 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 all that again only now you add food coloring and use the flask that tapers like this you can focus the expansion of foam so it looks maximum awesome [Music] so in order to fill a pool with this stuff if 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 deal 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 cake bomb 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 by-product if you watch it infrared you'll see the temperature of the foam right after the reaction it can reach almost 200 degrees Fahrenheit so because I'm nice I shelled my revenge plans and just demonstrated what would have been their fates 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 Showtime [Music] this one is called the melted unicorn [Music] [Music] you might recognize Bob flute Felder 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 [Music] and so with the success of the sideshow 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 elephant's toothpaste you want to tell the good people who owns the current world record Bob idea you want to tell our good people who's about to not own the world record Bob pretty confident aren't you 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 the neighborhood we're going to cover in the process only time will tell and chemistry which I don't understand but who else do you 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 then you have to cut up in a hundred and eighty one-pound bags of yeast but that's why we have sides Bob come on up they said it'll be fun they said [Music] this is an emergency tarp system so if we did on that right it shouldn't overflow in the case that it does give these tags here to contain all of the phone not going everywhere in the yards we hope for the best plan for the worst [Applause] we built these three frames for the tarps that would contain the catalyst ease 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 to Kevin let's go time baby we're probably like seven minutes out got a bunch of kids inside or just raring to get out the challenge here is this water is warm we didn't build these containers big enough so this will start rising so it's sort of a race against the clock the port starts overflowing we still have two so [Music] this looks terrifying as I stab this bloody thing think I'm about to get demonetized this is what will actually make the bubbles so if isn't part of the reaction so after a few final touches we were ready to go then before we got 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 he or she is to one go [Music] so the good news is we broke the record the bad news is we're kind of overachievers oh it's coming up the great tsunami hey hold this okay stand back off the chart oh we need to grab them stand back hold this up Bob okay [Music] so we pushed all the foam back into the pool that gave it some time to cool down so we could actually touch it [Music] 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 [Music] 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 [Music] all right Bob sorry you're looking at obsolete piece of material there I had it for over a year you did have it forever here but all good things must come to an end but 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 I am so much of our lives today revolve around apps and websites that requires secure passwords that's why for seven years I've been using LastPass we also happen to be sponsoring this portion of the video I've been a massive fan of what they do for so long because they free your brain from the burden of remembering all of your passwords so you no longer need to store them at using low-tech methods or worse yet in your own memory it works on both desktop and mobile for both iOS and Android and it's integrated into your phone so it comes right up for any website or app and it will automatically fill up with your username and password with no typing required you get unlimited password storage and it syncs for free across all of your devices plus it's super secure because your data is encrypted and decrypted at the device level to even the LastPass doesn't actually know what any of your passwords are so if you're finally ready to give your brain a break for remembering all your passwords click below to find out more about LastPass thanks for watching [Music] you

This is literally how I found out he died like literally what the fuck YouTube I know I hadn't been subscribed for like a year but that dude was basically my childhood

I wondered why he was wearing a TKOR T-Shirt and then I saw the “dedicated to Grant ....-2019”
