I recommend switching the dawn pro for dawn ultra. Dawn pro has some anti sudsing ingredients in the latest versions that cause it to not work as well. Looks like you got good results anyway though. Nice job

[@Engineezy]

Good to know! Thank you

[@jammerzz]

ultra is some good shit. kills the hell out of fleas. if you was a dog in it.

[@MorleyKert]

You gotta take that rig through a parade!

[@Zyghqwyv]

hi morley

[@Engineezy]

That would be fun!

[@GrumpDog]

Neat idea, but probably would be hard to pull off right, in practice. Getting the rig lined up with the wind would be difficult within the constraints of a parade, and parades often don't move quickly enough, if there's no wind.

[@randomstranger1188]

Might need to add a few things, but I am sure it is doable. 1. Make the vehicle smaller. Cars are cool, but may not be the best suited for bubble creation. 2. Put the vehicle near the front, or at the front, of the parade. This ensures that it doesn't stop, or rarely stops, and so maximizes the time the vehicle can generate it own air. 3. If it is a very slow moving parade then the addition of a way for the bubble maker to swing around to face in a direction that it can pick up the natural wind. These 3 things would make the design more feasible for Parade use. Though honestly the wagon design would probably be sufficient.

[@oljobo]

Love the hypothesis, great video 👍🥰 A bubble is always heavy, due to gravity. Please experiment using a heat source, so that it becomes a "hot air bubble" - this can be tuned to a gravity neutral, or even rising bubble. If you also use a fan, you don't need a moving vehicle. I experimented with this - small scale/short time using a hairdryer (pulled back a little) as an air supply. That was very promising 😊

[@Engineezy]

Hot air could be a great option! With the fan, at some point it may not move far enough, not too sure!

[@yavuz5282]

@@Engineezy with hot air driving it up, fan may work just fine.

[@Randomdave02]

The heat will evaporate the thin layer and pop the bubble, it will also add uneven air flow which in turn will cause the bubble to break

[@mattw7949]

You are absolutely living the dream. I hope this gig works out for you forever. As an old engineer who has to build "productive" stuff for my day job, and only build fun stuff in my spare time, it brings me joy that you can do this as your day job. Keep up the good work.

I needed to see the failure this morning, i too can overlook the track to the solution. Seeing someone who is definitely smarter than me struggle and be confident in the solution and still going "nope nope I'm still wrong, hang on this is the part where we learn why" i needed this.

[@Engineezy]

Glad I can be of assistance through my failures!

[@lucienwerner]

This video shows that nearly always the simplest design is the best (not always the easiest to find)

[@Engineezy]

It's very true! And sometimes requires a complicated process to get there haha

[@mattw7949]

Being comfortable with failure is part of the process that a lot of people just don't get.

[@thgersrensen1855]

As a fellow mechanical engineer, who has spent quite a lot of time designing a foam canon and working with a lot of soap, well done! 👏 An infinite bubble of course cant be done, as the bubble bursts when the liquid in the bubble falls to the buttom side and the top of the bubble gets to fragile. One idea that would be extremely cool: put a fog machine on the roof of the car and make huge fog bubbles! 🍾😊

[@Engineezy]

That would be awesome! The popping 😱 might have to revisit that in the future

[@Mrcheesebumble]

Whoa cool fog idea

[@ryangross5446]

so what youre telling me is he just has to go up with it to keep adding liquid to to the top of the bubble

[@thgersrensen1855]

@@ryangross5446 what I'm saying is that as long as you are doing it with gravity present, the bubble will burst at some point. There are however ways to extend it's longivity. The lube he adds works because it slows the fall of the liquid and adds rigidity.

[@brendan6747]

​@@thgersrensen1855 I believe he's using way too much liquid and the bubble would last way longer if it was uniform

[@mattpreece6453]

I guess all bubbles burst as the water evaporates… you should collaborate with someone who lives in a tropical area where the humidity is higher and see if you can get the bubbles to last longer.

[@Engineezy]

Thats a great idea! Although the humidity here in the summer is about as high as it gets haha. Might be some other factors

[@Randomdave02]

Evenings, areas where a breeze flows off water or shortly after a rain will maximize the bubble life. Low dust, away from airports, and away from smoke from forest fires, the particulates pop the bubbles as well. Distilled water and knowing the test results from the baking powder and guar gum will help increase the quality of bubble.

[@airgapmachine]

Have you tried using remote control to close the wand arms and, therefore, the bubble? If timed before it bursting you’d have some actual bubbles.

[@Engineezy]

I was too focused on trying to make the bubble go on forever haha! Might have to bust it out again

[@MasonCarlisle-f7n]

LOVE IT!! One of my favorite places in my hometown was a children’s science center and you would step onto this raised platform that was sunk into the ground next to a moat of bubble solution and there was a pulley system that would lift a rope hoop up… needless to say it was not 50ft, but it was always cool as hell to get a floor-to-ceiling bubble tube that was at least 20ft pop right in front of you and watch it disappear

Bubble science is surprisingly fascinating. I saw some research with them finding all sorts of uses for bubbles. Utilizing them in different tasks. Also I saw NASA recently measured a giant bubble that is around our entire solar system that is created by our sun's cosmic rays lol. I guess that boundary layer interacts with the surrounding cosmic neighborhood. That might help us learn more about space. Like the interactions between stars, galaxies, black holes. It's interesting to think the study of bubbles can span from very small scale systems to very large scale systems? I recommend looking up and watching videos that focus on the research & studies on the science of bubbles. Nature really is fascinating and I think bubbles just have this natural way of getting us to ponder about physics and all the other ways that Nature behaves. Bubbles are fun

[@TomNoddy]

Very nice. I appreciate the fact that you started by looking into the work done (or at least the results of work done) by others interested in giant bubbles. There will be a gathering of bubble people in Cleveland this September … you or others might be interested. Allow me to comment on a few of the suggestions that others have presented on this page. I think that it’s fair to quibble about whether an open bubble is actually a “bubble” but it is one of the records that the Guinness people considered and there are different records for these long open tubes as well as closed bubbles . Some have suggested that evaporation is a concern regarding the popping of soap bubbles and, yes … bubbles are typically thinner than wavelengths of light (it’s why they have colors) so only a tiny bit of its tiny bit of water needs to evaporated on any portion of the bubble/tube and that will happen more quickly on a dry day than a humid one. Others mentioned the quality of the air and that is certainly a concern to people making big bubbles. The tiniest bit of dust or pollen in the air has the ability to do to these monstrous bubbles what children do with their fingers … pop. But I don’t think that these videos show popping that comes from those common sources. Left in the air long enough, evaporation will certainly become a concern but most of these bubbles popped either from the stress or from touching the ground. Alan McKay, in Wellington, New Zealand set the record for bubble tubes of this sort when he created one that was 105 feet (32 meters) long. Alan pioneered this idea of using long poles and string, a device that bubble people often refer to as a Tristring. He didn’t use a car and in his experiments, his poles got longer and longer as he found that the limits were mostly related to the giant bubble tubes touching the ground. On the day of his record, he credits the wonderfully cooperative breeze that helped hold up the thing as he backed into the wind and kept walking (no car). Others mentioned the possibility that the turbulence around the moving car was breaking bubbles and that is something to consider but I don’t see much of that. That polyethylene oxide in the J-Lube has made the bubble extremely flexible and we see it responding to the wind, the movement and the turbulence by distorting from the bubble’s preferred spherical shape in response. But the thing often splits up into multiple bubbles rather than burst when it is that flexible. This is a wonderful video, thank you for showing us. The concerns that you faced have been addressed by others and the idea of pumping fluid and widening the opening and increasing the speed have also been addressed. Consider coming to Cleveland this September or look for the organization called AOIBA, an international group of bubble people. You’d fit right in.

[@Engineezy]

Thanks for the detailed comment! Really interesting about the 105ft bubble. Also, the pollen in the air could definitely be a factor. Appreciate you watching!

[@faradaycage370]

Maybe try adding glycerine to the bubble solution. It helps keep the water in, as far as I know.

[@MasterHen01]

[@Engineezy]

[@victorsvidss]

Try this one. The humidity is higher on a cloudy day. Water will evaporate much slower from the bubble. You could probably get a bigger one

[@Engineezy]

I will definitely have to try it 🙌

[@bobfels5343]

This is soo awesome, also cool you show that failing not bad, but you can learn from it. I wonder why you put it on a car instead of using a fan? Like heat the air a bit and blow it a bit under an angle or something. Easy to type on youtube comments, I know it has a lot of complications :). Thx for the awesome video!

[@Engineezy]

I’m not sure how far a fan could go, this just seemed like the best way to do it! Thanks for watching

[@chriscanal999]

Awesome! Could you put a heater on the car so that the air in the bubble is warm and the bubble rises into the air? Maybe it wouldn’t pop as soon as

[@Engineezy]

Thats an interesting idea! Might be worth exploring

[@nickmorrison3979]

I am excited. Based on your proposed hypothesis my prediction is as follows. 1 as the bubble expands in volume the surface area will increase by significantly more, this requires more solution. 2 in the event of perfect theoretical execution there would eventually be a point where the solution could not travel from the source to the end fast enough to overcome expansion. In summary, i predict a maximum limit even in ideal circumstances. I hope i'm right

[@Engineezy]

This is good logic!

[@KastanDay]

Amazing work man! Please, you have to try it indoors! Some big warehouse or stadium. Vehicle notes: attach this to an ebike or scooter. I think you have to reduce air turbulence near the bubble, seek inspiration from airplanes. The ideal vehicle might be a flat e-motor 4-wheel "electric car skateboard" with the 2 servo-actuated arms sticking up.

[@Engineezy]

I would love to try this indoors! Maybe one day. An e-skate could work well!

[@LackingSense1215]

This was fun and entertaining to watch! Great design and idea along with amazing filming. Good show and tell of the concept of the idea to the planning and the execution. The bubble really looked awesome! Better than some of the CGI that is used when trying to make bubble like physics. Especially in sci-fi. I wonder if maybe you will inspire some film directors to use your idea as practical effects. Thanks for the hard work! Good luck on your other ideas can wait to see more!

If you put an adjustable spoiler at the front of the roof of the car, you can play with the dymamics of the air going into your bubble, it looks like it needs more air, but not faster air. I have a suspicion this will be like tuning a carburetor, but infinite bubble probably is possible.

[@1980cboy]

Yep, so many factors play along in making giant bubbles. Wind, UV, Humidity, Temperature are the natural factors. Then there is the mix also. Even if you have a good recipe it may work one day beautifully and another day it doesn't. Best way to make bubbles is actually inside where you have more control on the environment. Best way to try to make the biggest ones are in the morning dew (lot of humidity, not too hot) and with just a small light breeze. It does help to make bigger bubbles with adding/pumping more liquid, but that creates only more film on the wand, while you move a long. This means that the first film which is moving away will eventually dry up and burst. So I don't know if it is possible to make an endless bubble. My biggest bubbles were about 6-7 meter without pumping liquid.

[@Engineezy]

Those are some serious bubbles! Would love to try it inside, maybe one day

[@sug15]

Dude this is awesome. Other suggestions, maybe others have already mentioned - you could inject a small amount of helium into the bubble so that the total bubble + film is neutrally or positively buoyant with air and the bubbles don’t slowly sink - you could put a fan below the machine and point is up; then the helium+fan both cause the bubble to rise, even when the bubble is outside of the fan’s range

[@Engineezy]

I was thinking the helium concept could definitely work! The helium plus fan is even better

Giant soap bubble-tunnel looks awesome

[@giganooz]

I wanna see hot air balloon bubbles. Use a static ring, but release hot air in a big distributed area beneath it and around it. Shouldn't just make massive bubbles, but might also make them fly. Even better if you use a lighter than air gas so they can keep rising. If you wanna get real spicy with it, use some hydrogen in proportions that are just barely flammable. Then shoot the bubbles with some kinda fire projectiles for a very cool game.

[@Engineezy]

That would be a fun game! Love the ideas

[@scottgriz]

@Engineezy Did you try closing the wand back up after generating a giant bubble to see if it would begin to spherize itself? I know that wouldn't make them as large but it would be cool to see how large of a sphere you could make.

[@Engineezy]

I got too focused on making long bubbles!

[@supergiantbubbles]

I don't think you got either the largest bubble or bubble making machine, but that was a really cool project! I've mulled over ways to pump bubble fluid to my strings when I'm making giant bubbles and came up with a solution that was pretty close to yours. Ultimately the most important factor for making the largest giant bubble possible is the air quality, with your bubble solution being the next most important factor. Technique is another important thing. You would have better luck with some smooth laminar offshore ocean wind in the morning. Your car was creating quite a bit of turbulence in the air that filled and surrounded your bubble. I say all of this with about 15 years experience making giant bubbles.

[@Engineezy]

Thank you! Good stuff to know for the next attempt! Cheers

[@robertstark3326]

I love your channel and your attempt at making those huge bubbles, but as far as I am concerned, it's not a bubble until you close up the strings and seal the end up. The bubble must be a closed shape and must float intact for at least a second or two for it to be called a true bubble. I would describe what you made as a soap tunnel not a bubble.

[@Engineezy]

That is fair! Maybe the world's biggest soap tunnel?

[@IdealIdeas100]

To qualify for worlds largest bubble, I think the bubble needs to be closed off at then end. But youre easily breaking the record

[@Engineezy]

Probably right! Gonna have to work on that technique

Longest free floating bubble. Alan McKay New Zealand 32 meters long 09 Aug. 1996

[@WinstonMakesMore]

Showing how to learn from failure is something we need more of. Nice build. Two things tickling my brain: 1) I bet there's some turbulence from the car itself that's destabilizing the bubble. 1.5) you could build a foam fairing for the back of your car like hypermilers do. Or maybe use a fan...? 2) To help weigh down the string and ease overall weight on the rods, the tubing could come from below and run up the wicks maybe...? Just spitballing here.

[@Engineezy]

Thanks Winston! As much as I wish I could get it right on the first try every time, its just not the way it works! The turbulence thing might be a factor. Although I wasnt moving that fast so I would guess the air is still in a somewhat laminar state. This would be cool to cfm! A fairing could be cool to test! Running the wicks up may help, only one way to find out 🤓
