Real Hoverboard Using Ground Effect! - Floats On Anything!! 

How do these guys do so much engineering.. but then never thought that water would just get blown apart? Great video! Those self lacing shoes are genius!

This man not only builds a working hoverboard but he casually adds in self-lacing sneakers. Amazing work!

As a _Back to Future_ fan, I greatly appreciate someone stepping up to the promise scifi media made to fans so long ago! Thank you!

I bet you cant summon a Yu-Gi-Oh card like they did on the tv show

every single one of these video makes me want to learn more about science. it really reminds me of how Vsauce can make science actually interesting and relevant while also being funny and inspiring.

Finally someone who doesn’t just use magnets over metal 😂, nice job man!

There are engineers and then there are dorkgeneers that forcus their big brains on bringing popculture to life without movie effects. You do a great service sir!

I can't believe the amount of engineering over 2 years to accomplish this board, and they didn't account for the fact they are just going to displace the water with the fans and gravity was going to do the rest? x) Props to them regardless, looks like they had a ton of fun and met some pretty cool people along the way! :)

I knew it wasn't going to work on water but a totally sick build, man! 🔥🔥

SPOILER ALERT: I'm surprised that those guys are smart enough to build such a complicated project like this, yet they did not predict that it would obviously sink and be instantly flooded by water. Anyway, congratulations on making it hover at least over land, that's an amazing feat.

J laser and the hacksmith together = future force industries.

Tbh I am more impressed on the use of nitinol for the self lacing shoes. Most people went for the complicated route of motors and stuff while you solved the problem while displaying the core fundamentals of engineering: making it work as simply as possible.

The video and hoverboard were amazing! Honestly, you've done so much, it's hard to imagine something new. However, I've never seen any attempts to recreate the gauntlets of the Shocker. It would be fun to look at their works, if it's possible that is.

In the future, when we have actual hover boards, we’ll look back at videos like these the same way we look at those old videos of flying machines and just be amazed at how far we’ve come!

Last week, my uncle advised me to watch this series of films, so yesterday I watched all 3 films at once, I am absolutely delighted, this masterpiece is in my top! (I am 16 years old)

I just bought your web shooter for Christmas and I love it!

Your dedication is inspiring.

As [I am] an engineer, [my opinion is that] you presented all of these super cool scientific principles in very accurate and digestible ways. I love how you walked us through all the levitation methods that don't work at scale, but still make use of interesting phenomena. Thanks for inspiring the next generation! [Edited for clarity]

Dude, you have to be the best engineer I have ever seen. Dude, may self lace shoes like it was notting.

Omfg this video kept me on the edge of my toilet seat. I was 60% sure that it would go over water and 90% certain that it would also dip into the water and die. Awesome! I loved how you also just kinda made self lacing shoes along the way as a side project.

If you add some sensors that measure the distance to the ground and use differential thrust to make it more stable, this could 100% work like in the movie and actually be pretty easy to control.

I'm really looking forward to seeing how the technology evolves over the next few years, and I'm hoping to see more of the hoverboard!

I can’t beileive that you are so dedicated and kind.

Suface tension young man . Physics is awesome . Nicely done.

I like how you explained every possibility, even though some were ridiculous from the get go, but you explored each option and explained the science. Great video.

When I was in Jr. High, my science teacher had a working hoverboard that he built, and would occasionally bring out into the hall to let his students try sitting on. It was done with air, but I don’t know exactly how it worked. I think I remember it being quite loud, but this was around 10 years ago, so my memory isn’t great. It always surprised me that nobody had tried this on a larger scale before, when we obviously had the technology and know-how to do it. This video brought back that memory to me, and was super neat to watch. Thank you!

Im to late, but still wanted to say thank you for being these principles to millions of people. As engineer myself its always cool to see things like this and hope multiple people get inspired and push us to new innovation in the future. Together we can overcome current and future world issues.

Pages like this keep me excited about the future

I love the start of the video explaining all the different options considered and a little bit of the science behind each one. This is the essence of engineering!

You've been probably the most accessible youtuber to help get my kids excited about engineering. Easy to follow. Always cool. Appreciate what you do mate.

Bro what literally crazy is i saw another hoverboard video and I was coming here to suggest this. I knew if anyone could do it then it would be you. Then I seen you legit did it already 😅👏👏👏 Bravo

I always click on these videos never expecting the final product to be anything like advertised in the thumbnail, and yet the man never ceases to prove me wrong.

YES FINALLY someone who used the use of air flow over magnetic force Ive been commenting that over every hover board video the design was sick but i want to see what idea would you give for mininmizing the size

Not even gonna lie, never heard of this channel and didn't cone in expecting much. I. Was. Wrong... Im blown away by the amount of work you put into your projects and videos. Incredible job, definitely subscribed from now on!

You always pull off miracles, man. Love this stuff!

I’d love to see you make camouflage armour like the predator has when it uses bending light / reflection to hide in its environment. That would be cool! Great work keep up the amazing content! Thank you 🙏

There's a reason it's called the "ground" effect and not the "anything else" effect. To work, it requires that the surface is not deformed by the air; this holds for solid surfaces like concrete, but not for water.

RU-vid needs a double-like button. Awesome project. ❤

I believe the final test over water 'may' have been achieved if the curtains were applied; similar to the hovercraft method. Congrats on the ground-effect hoverboard 10/10. 🏆

Amazing video man.. Crazy engineering work

The hoverboard and shoe laces are super sick that you made. When you asked for a suggestion of what to make next I was thinking about part of the video how you showed the way sound can make objects levitate. I have also heard of frequencies being able to move liquids and solids as well, that being said it would be super cool of you could somehow make a Harry Potter wand that could make objects move around or even come to you by using sounds and frequencies. Is this doable?!

i like the logic of hovering around with a air compressor would be weird so we strapped 27 high powered EDFs instead xD a great build as always, love the buildup of testing various ways to achieve the goal and showing us that process instead of just brushing it off and saying other ways failed. Much love

To jlaser You are so good at what you do i would never be able to do this you basically risk your life to satisfy us with your genuine smarts and wonderful inventions thx for all you do man

This is an awesome video, your dedication and engineering prowess are inspiring. If you made it like 10-20% more powerful so that it didn’t need to fully rely on the ground affect, you may be able to get it to work over water and move independently without too much extra power / danger. A hover board that uses drone control to keep you at 3-5 feet and make steering easier would be a pretty viable product.

I'd love more engineering collabs! You're amazing! well done!

If you use the downward air from the outer fans to trap a high pressure under the middle of the board, you can use less fans, less batteries and electronics, and seal holes, making it lighter and more effective. For water you will need to interact with a larger ground effect region so your bouyant force doesn't go so low into the water and splash up, meaning you need to make the board wider and keep the fans away from the surface and splash, or keep the size and place the fans higher, interacting with more air and trapping more volumes of high pressure or velocity air. This is why hovercraft use skirts, because you can pneumatically fill the area with far less energy than continuously jetting yourself off of atmospheric mass and ground backpressure.

I am happy to find someone with a brain and imagination at the same time.

And I’m impressed of what ur doing with ur channel!!

I used to search it up in 2016 when people made a miniature sized actual floating hoverboard from Back To The Future. This is definitely great to watch.

Dude, what an incredible video man. So insane to see how you're able to document multiple processes over months and years and keep things moving forwards and then still tell banger stories about them! Truly a pleasure witnessing and watching this journey!

WE GOIN BACK TO THE FUTURE WITH THIS ONE🗣️🗣️🗣️🗣️🗣️🗣️🗣️🔥🔥🔥🔥🔥🔥

I’m so hyped for the spring ring

Definitley one of the better hover boards I’ve seen online. Nice work for sure

I'm really not scientifically inclined but I always enjoy watching your process and appreciate some of the layman's terms you use to explain them 👍

This video is so awesome I see people building stuff for no reason no purpose tons of money wasted BUT THIS VIDEO WAS WORTH EVERY PENNY EVEN IF IT GOT RUINED LOOK AT WHAT YOU CONQUERED AND MADE SCREEN SHOTS OF THE ACTUAL MOVIE I KNOW MARTY MCFLY WOULD LOVE THIS I BELIEVE THIS IS THE BEST DIY VIDEO I HAVE EVER WATCHED CONGRATS BRO IT MAY NOT MEAN MUCH TO ALOT OF PEOPLE BUT THIS MADE MY DAY

well done and calculated. showing my kids that anything is possible. thanks for the vid

The way you made the self lacing shoes are genius. When I saw the hacksmith make a pair of self lacing shoes they used motors. This was such an amazing idea of self lacing shoes.

As a skater who always dreamt of making something like this but couldn't figure out how to make it work without a magnetic field or an engine so big that would be completely different from what I envision, I would buy this. I want to buy this. Take my money.

Wow! Such commitment (Or should you just be committed?😀. ) You actually made an exact replacement ("It doesn't work on water.") 😜I am astonished at your ability to solve one problem in such a myriad number of ways. I especially like the "floating in sound" demo, wonder if that would work supersized at a Taylor Swift - or Rolling Stones - concert.

Im really happy you made this. It was actually Back To The Future that inspired me to be a Film major, and seeing it come to life is making my inner child happy, so thank you on behalf of the 12 year old version of myself. As for a new project, you should make a whip that magically wraps around objects like in the movies, being able to grab or wrap something from a distance. ❤

Never seen someone actually do a back 2 the future hoverboard so well, I honestly thought you would have tried to put something to stop the water from coming in and not just go for it but you're right you did nail it just like the move. I'd also really love those shoes lol.

This video is epic. Never have I’ve seen anyone created a DIY hover board.

Great Scott JLaser! You Made My Dream Come True!

That is amazing! I would recommend adding some sensors to it to auto balance to stay level and add a few more thrusters on the rear to propel it forward.

seeing a hologram like the ones from star wars would be really cool, don't know if that's possible but if it is that would be an amazing build

Great work guys!

Love the "We nailed it" at the end there 😂 Hope you can salvage some parts for another project 😉👍

It’s so cool to see now you can do this, just imagine what can be done in 10 years 😮

When I was about 11 I absolutely loved back to the future and magnets, so with my love for back to the future and my knowledge on magnets I wanted to try do the same thing as the toy hoverboard but couldn’t afford the magnets, it’s nice to see it come to life. Would love to see more movie objects outside of marvel and dc

Great work I seen many projects of hoverboar you are the closest am awesome

The shape makes it awkward, I also think you could've used less EDF to make it less clunky. I suppose after the fine tuning above, making it fly forward without a tether as help would be amazing. Y'all are the engineers I'll let you figure it out. Respect from Canada 🤙

This is incredibly amazing! As a huge Back to the Future fan, I think this is the coolest thing ever. Your channel is super inspirational and entertaining.

Pushing the limits, nice job guys! Keep engineering and making history!

Another great vid, mate, blowing my mind as always! I would love to see you try some sort of Thanos glove that can make objects disappear.

That dang thing works better than I thought it would , good job 👍 please don't hover board in traffic while testing it , be safe so you can make ver 2

The super conductor part is very interesting- I never knew it stayed in the magnetic line of field. Love your videos!

I know super conductors won't work for this project, but for future reference if you need a bunch maybe consider teaming up with NileRed, he made himself a bunch in the past. Also I'm an electrical engineer myself; you said your scared of those fans getting stuck on at full load, but have you considered using a short circuit safety relay or something along those lines to current limit the supply? I can think of a few things you can do to prevent such a thing from happening. So obviously your using DC so you're not using a VFD (variable frequency drive) to control the speed of the motors, but you have to he using some kind of drive that's using resistance or something that's controling the speed of the motors and usually there you configure a safety limit too. It's alot easier to do it with a VFD on AC motors using hz, just because limiting the frequency that the VFD outputs limits the voltage too because they go hand in hand, for instance if you do 30hz instead of America's standard 60hz that's half the cycles so it would be half the voltage, so being that you get alot more control over AC versus DC a inverter might not be bad idea for another project. Current limits, hertz, list goes on and on what you can do with a VFD, I even have limited AC motors to certain amount of RPM's.

That plank with fans is actually super similar to something my neighbor made when we were kids. It was made with the exhaust from a vacuum though. Fun project for a couple of kids lol. Only limited by the length of the extension cord.

Nice work my friend! AWESOME VID

I plan to go into engineering. Man is an inspiration. Would love to see some crazy car mods

So cool. Emulating the movie brought back so many memories of my teens. Thanks.

These videos have been the reason im into science.

I think the most impressive thing is how you made a solution to the self tightening shoes with a simple technology

Great work as always. I've always wanted to put a remote in a deluminator prop to turn off/on my household lights.

A good rule of thumb. If its going on or near water. Just make it water proof. Dont even bother not considering it. Just do it. Also. Drainage. Water will get in, so give it a way to get out. Think about your directions of momentum and place your holes accordingly.

I’m glad to hear you’re still working on the spring ring. When do you think it’ll be available by?

Good work on making the hoverboard

Good to see someone is keeping the quest to unlock the secret of hoverboard alive for all us BTTF fans out there!

Your videos keep amazing me! Maybe for the next video you could make the fully interact screen in the window like in Iron Man 1 in Tony Starks bedroom. I always found the usage of handsgestures, no matter where in the house amazing.

My wife is OBSESSED with back to the future and I’ve been trying to find one of those hover boards for a long time

Thats just mesmerising ❤❤❤

15:59 I think it's hilarious that it's still a burger king 40 years later Edit: That's a beautiful lake

Could you try making a paraglider that can be deployed like a normal parachute and also automatically refold itself after you've landed so that it's immediately ready for use again? It would function like pretty much every glider found in video games.

Great video. I was wondering if the hover board would work with an air curtain around the outer jets to keep the air under the board instead of blowing out around the sides. Or angling the outer jets inward instead of all being flat. Anyways Glad I found your channel. Looking forward to seeing the others videos.

Nicely done man!

Wow!! Even though the board didn't go over water just seeing the effort is the most inspiring thing to see..who cares about the outcome it's the Intent that matters.

Everything you make is always so cool! Keep up the good work

Flying things before gta 6

This is my favorite science channel on RU-vid. This guy makes stuff as accurately as possible without shortcuts

I’m actually a huge fan of back to the future and this really made my day. Even though I just discovered your channel, I would love to see more Insane projects like this; bringing fiction to reality 🤩 That small prototype toy is also something I would love to have😅
