  • This is the world's first ever actual pool of Jello!
  • And while it may look simple, it's actually a very difficult engineering challenge to pull off.
  • As proof, if you Google "Jello Pool," you will either find bad CGI,
  • or a handful of videos of people who tried to do this, but it really didn't work out.
  • So today, we are going to answer possibly the longest standing question from my childhood:
  • What would it be like to actually belly flop in a pool of Jello?
  • But before we do that, I want to talk about what we
  • actually had to go through for the past 6 months to pull this off.
  • The idea of a Jello pool has been on my bucket list for over 4 years.
  • In fact, when Kevin from The Backyard Scientist and I made the 25 million Orbeez pool,
  • our first idea was to do a pool of Jello, but it's really hard.
  • Because if you've ever made Jello, you might recall
  • you first have to boil water, then mix in the powder,
  • and then you have to refrigerate it for it to actually get firm.
  • And that's easy enough to do for a small dish
  • but how do you boil and then refrigerate an entire pool?
  • This seemed like a very worthy engineering challenge.
  • So year at Thanksgiving, my brother and I came up with a plan
  • and then in the middle of winter, we started digging a hole in his backyard.
  • Then over the course of 2 months we set up a bunch of small-scale experiments
  • because we needed to answer questions like:
  • How much gelatin powder does it actually take to get to the ideal firmness?
  • And how hot, and then cold, does the mixture actually need to get
  • for the Jello chemical reaction to take place so it will actually get firm
  • From our experiments, we learned that the Jello always got firm as long as
  • the mixture got hotter than 160° Fahrenheit.
  • So we decided we could scale this up by using
  • 6, 55 gallon drums with a custom propane burner underneath
  • and a spigot we welded to the sides, but more on that later.
  • So now we knew how we were going to heat it up
  • but how do you refrigerate an entire pool?
  • For that, we teamed up with Mother Nature and just picked
  • the perfect location and time of year.
  • We installed a thermometer and starting in January
  • we tracked the temperature in his backyard every night.
  • We needed refrigerator temperatures at night,
  • but not freezer temperatures, because that would freeze the jello
  • and our experiments showed that totally ruins it.
  • And so after looking at our data, plus historical
  • temperature plots, we knew we had about
  • a 3-week sweet spot window towards the end of April to pull this off.
  • Our goal is to have a Jello pool party
  • in his backyard, that would make even
  • Phineas and Ferb jealous.
  • So the plan was to start 7 days before the party,
  • and fill the pool with an average of 10 barrels every day.
  • That would give each layer a chance to get exposed to
  • the cold night air, to more efficiently get rid of the heat.
  • And so with that, first thing Saturday, a full week
  • before the party, [water splash] we got to work
  • ♪ Faidherbe Square - ProleteR ♪
  • We didn't want to waste actual food, so this was just
  • water and gelatin powder and food coloring.
  • But there's no sugar.
  • ♪ Faidherbe Square - ProleteR ♪
  • We intentionally placed our barrels much higher than
  • the pool, so when we're ready, we can use
  • the potential energy to move the Jello from the barrels
  • to the pool.
  • We had to tackle about a thousand other issues that
  • came up, that I won't bore you with, but
  • day by day, and layer by layer, the pool
  • began to fill up.
  • Because the Jello went in with so much heat energy,
  • we needed to remove before it could get firm,
  • in addition to using the cold night air, my
  • brother's neighbor, Nick, happened to have a spare swamp
  • cooler, in his shop.
  • So we kept that running over the top of the pool,
  • pretty much the whole week.
  • This gave us convection cooling, it's
  • the equivalent of rolling down a car window
  • for the pool, or like, when you blow
  • on the top of a hot cup of soup.
  • This constantly replaces the evaporating layer of air
  • right at the surface with fresh, cold air,
  • that will suck out the heat more efficiently.
  • And so, as we put in the final batch Friday night
  • with ominous weather
  • threatening to ruin the whole effort.
  • At this point, we had done all we could.
  • We were exhausted after a week
  • and I wasn't feeling super confident
  • because my specialty is more of mechanical things
  • and this project was more about chemistry and thermodynamics.
  • And I didn't want that lame "Jelly-Baff" stuff
  • people trying to pass off as Jello.
  • And so even if it didn't last long in the Sun,
  • I wanted to at least have the experience
  • of seeing even a single belly flop
  • on a smooth pool of actual Jello.
  • If this was gonna be a total failure,
  • it wouldn't be from lack of effort.
  • And so we woke up Saturday morning,
  • with a forecast for a warm sunny day
  • and we pulled off the tarp
  • to find a pool
  • filled with actual freaking Jello.
  • ♪ Sappheiro - Falling ft. eSoreni ♪
  • By this point, word in the neighborhood
  • had definitely spread around
  • as to what we were up to.
  • And my brother asked if some of their friend's kids
  • could have first dibs.
  • And so with that, I'm happy to report
  • this is what it looks like to belly flop
  • in a pool of Jello.
  • ♪ Sappheiro - Falling ft. eSoreni ♪
  • Not yet! (Wait, wait Adam)
  • ♪ Pokemon in NYC ft. Missy - Andrew Applepie ♪
  • When I first got in myself,
  • it was closer to the middle of the day and one of the things we discovered was that
  • direct sunlight over time
  • had the effect of undoing some of the
  • solidness of the lower layers.
  • (Laughter)
  • When you go in it just feels-fills your nose
  • and like ears. It's a very surreal feeling
  • I'm just being like. Its kinda hard to move
  • but its just slimy and slippery
  • It actually feels really cool
  • We have some pool toys uhh... hidden underneath
  • Got it!
  • Wow!
  • It's unlike anything I mean it's like swimming in snot.
  • If that makes any sense?
  • But like a good snot!
  • To keep solid for even longer, if we were to do it again
  • We might put in a heat exchanger pipe system beneath the surface
  • sort of how like they freeze indoor ice-skating rinks.
  • And maybe use a little sugar
  • That's disgusting!
  • Now at this point you might be thinking "Why would anyone spend their
  • effort of 6 months of planning, and then a solid week of back-breaking effort just to make a stupid pool of Jello?"
  • And to that I say,
  • "Why do people go through the effort of climbing Mount Everest?
  • Why did Neil Armstrong go through the effort of stepping on the moon?
  • And why did Pam and Jim go through the effort of convincing Dwight, that Jim had always been Asian?"
  • Dwight: "This is Jim."
  • Sometimes, you don't do a thing because you should, but simply to prove that you can.
  • Now that my curiosity was fully satiated and on my ongoing quest to be the favorite uncle,
  • I told my nephews they can invite some of their friends over
  • And my brother's family, setup a neighborhood BBQ.
  • And at this point, after a lot of hours of belly flops, and bowling balls, and direct sunlight,
  • The Jello was pretty broken down
  • But that didn't stop us from setting up
  • a Jello pool slip-and-slide
  • ♪ Pata Pata - Matt Chene ♪
  • And I love their sense of adventure but it was a bit of an "Uncle Fail Moment"
  • because apparently, none of them have ever used a slip-and-side
  • ♪ Pata Pata - Matt Chene ♪
  • We didn't actually put any sugar in here so it's kinda disgusting so, we've got some real-

  • This was a Bucket List video idea I've had for as long as I can remember
  • and I wouldn't have been able to pull it off if it wasn't for the support of my friends at "NordVPN"
  • As I'm sure you know by now, by using a "VPN",
  • you can search the web anonymously,
  • you're location stays private
  • and your data is encrypted
  • And for my friends in the EU you might have heard recently that article 13 passed.
  • That means that a lot of the websites you love to use,
  • will be forced to be far more restricted.
  • I'm not saying you do this
  • But hypothetically, if you're using the VPN,
  • You can virtually teleport and trick the internet to think you're
  • In any country you want
  • (American Patriotic Song)
  • And "NordVPN" is the best because they have thousands of servers
  • in over 61 countries. Plus they have a 30 Day money-back guarantee
  • on super remote chance you try it, and for some reason you're not totally satisfied.
  • To virtually teleport around the world
  • or given today's headlines, if you're just
  • ready to take you're privacy more seriously, you can go to:
  • Or use this link in the video description for 75% off
  • they're 3-Year plans which works out for less than 3 bucks a month.
  • So it's
  • and if you use the code "MarkRober"
  • in checkout, they'll throw in an extra month for free.

Summary: Since I was a little kid I always wondered what it would be like to swim in a pool of Jello. Turns out it is really difficult. We heated up the Gelatin in 55 gallon drums and then used gravity to put that jello into the pool.
