My Homemade Jetpack Should Be Illegal 

I dare you to double it

In my opinion, Adding more thrusters in a straight line quickly hits the wall of diminishing returns. Instead, try mounting and stacking them in a cylinder and surrounding the collective ends in one large cone nozzle. This is how rockets are designed, with many burners in a ring inside of the larger cone that funnels the final air mixture in around them all. If you place them closer together in a ring and encapsulate them with a blast cone it should direct the collective force more efficiently.

I love everything about this, but your random songs especially make me smile ear to ear man 😅

looks like you're ready to take on the final boss. let me know when u want to come out and race

I swear Preston’s always in a good mood 😂 literally one of the most underrated RU-vidr!

This dude is single-handedly keeping the water jetpack company in business.

As an aerodynamicist I have one word for you - Streamlining! The mask, the, tank, the backpack - you'll break 20 mph for sure and that would be even more amazing. Great Show!

Only 12? Double it and make a second row behind it

preston may not be pregnant but he never fails to deliver

FBI: We heard you made your own underwater jetpack, we need to talk about your known associates. .

Only 12? Try double it again. I dare you.

Maybe a swimming cap and smaller goggles could lessen water resistance. Also placing some shrouds near the propeler intake to prevent seaweed or debris from cluttering it in every use. Hoping to see you break records with your cool ideas. More power :)

No joke: Preston never gives us up, never lets us down, never runs around or deserts us. Never makes us cry, never says goodbye, never tells a lie, or hurt us. Edit: But for real, Preston makes the best content on RU-vid for sure. I’ve never laughed this hard at something before. Seriously. Also the Mrbeast and Ryan Trahan songs are still stuck in my head lol.

You should see if Robert can get you guys into an Olympic Sized Pool to really push the jetpack and maybe move the two outer motors to the middle on a raised section or pair them into 4 sets of triangles to try to reduce the jets from interfering with each other

AMAZING CONTENT!!!🙏🏾😭loved everything the production is amazing, the comedic relief everything! This should seriously become a show

the true kerbal approach to problem solving, add more engines until you get the results you desire

Saw this at the top of my side bar and immediately clicked off the other video I was watching. So many great choices here. Like the scene in the water where we couldn’t actually see you but it was still captivating due to the music choice. Also that final “Double It” in the song is so clutch! If it’s true that we get better with time, I can’t imagine the heights you sill reach. Bravo!!!

Big fan. Double it next time

Seeing the aerial view looks like when David Hasselhoff saved SpongeBob

Instead of doubling it, Multiply it by Pi! Make an aerodynamic (or hydrodynamic?) circle frame around you that you can hold on to.

Yes

Fly to the Caribbean with this thing.

This video is next level awesome in every way from the videography and soon to be #1 iTunes hit about Jam Nutsto the overal humor and entertaining interactions. It was a great idea that paid off with a cool finish. Great stuff!

It would help to make yourself more hydrodynamic so you can flow through the water easily with less resistance. Make a cone or something to hold in front of yourself.

Watching Preston's videos before he has 1mil subs feels like being part of a secret club

A couple suggestions: 1.) You need a full face mask for air but one that is streamlined. You are probably losing about 20% of your thrust just to the drag from the mask and the bottle. 2.)Consider maybe a few slim air tanks inside a casing? The casing will alleviate some of the drag caused by the bottle in your mouth. I think with those two things you might be able to gain as much as 30% higher speeds. Have you tried them in depth? Try it at about 20Ft. No waves or interference from seaweed

Walking around the office singing "put more engines" is a great ice breaker.

Also Sprach Zarathustra was a great addition to your super gear moment. Truly goosebump worthy.

Just found your channel last night by watch the 6 jet jet pack video and I loved it so it’s perfect timing that you came out with this one today

This was so fun to watch! The music amplified it too. You definitely have a way of getting people locked in on the idea and also on edge/anxiously hoping you succeed. The Shopify spot was like slick!

Angle and 'wing' the support bars and then sand everything smooth and slick. I'm betting you could get 15 mph out of that setup. Excellent demonstration. Awesome vid. Liked your style. Thanks!

“Olympic gold-medalist Michael Phelps can swim the 200-meter freestyle in approximately 1.42 minutes, which equates to a speed of about 4.7 mph (miles per hour) or 7.6 km/h (kilometers per hour).”

Out of the hundreds of times that my brother's Strava account has been featured (for less than half a second) in a RU-vid video where an upgraded homemade jetpack is used to race a former pro swimmer, this is *probably* my favorite #putmoreengines Keep it up, Preston!

This mans a underrated youtuber he should have at least 10 million subs. Keep up the good work!

Awesome stuff! If you could 3D print a helmet / mask and body and oxy tank plates that are aerodynamic, which allows for less turbulence and drag to occur, I think you could drastically improve your speed and maneuverability on try number 3!

When I saw the test at the end, the first thing I thought was "I'd be most afraid of the camera ganking into the sand like a polevolter, than seaweed." Sure enough... you showed me what happens. Thanks.

Honestly glad I found your channel, your charisma is contagious!

Bro I hope I get to the point in my life where I can make a full on jet pack

Theoretically if you added more voltage to the motors you'd Definity go faster however you run into the problem of damaging the motors. Also it'd try to bundle them up as 2 cylinders mainly to focus on the jet streaming for better control.

Preston is always in a good mood. I love that I’m new to this channel. I already love it. I found it out today like it is the best channel ever.❤❤❤❤

preston bro i love the fact you didn't give up like bro you just kept going after all that seeweed shit and failure

Loved the video! Im not an engineer (Though I'm in school for it). I think this thing would be easier to control if instead of spreading them out across a single wide plane across your back, you had them in a two- high stack. Itd help the center of thrust stay more consistent. A more precise thrust vector could also help with speed, and itd be less unweildy too. Maybe youll never touch this thing again, but in case you do, that might help!

i like how he was afraid that he was gonna die out there and then became mad that he was gonna die out there bless this man

Nice and fun idea. You should try playing underwater hockey with it, maybe with a smaller version (4 engines).

this guy will always comes with a good content for his viewers

Preston is getting EVERY penny out of his auto tune purchase, and honestly, I'm here for it.

The last thing we need is this man double the amount of engines and build an exoskeleton suit to carry it

Great White shark: “That seal sure was crunchy …..”

Another amazing video preston, great content, love the positivity

Prestongoes should sneak into the Olympics with this!!

This has golden era RU-vid vibes! Congrats my guy!

To prevent the ingestion of debris, you could cover the water intakes with some sort of mesh (like on those small jet engines used in rc planes and random youtube videos)

DOUBLE IT AGAIN I DARE YOU! 👁👄👁 #PutMoreEngines

Your videos are HILARIOUS. Please Don’t stop innovating Prestongoes & everyone involved.

How have you not passed a mil yet? These videos are so well made

Blud out here tryna swim faster than aquaman

the cia watching this video:

Oh hey my comment made it in the video. W

Dude...im not even gonna comment on what was or is right or wrong with what you built...i'm just here for the entertainment value...and you my friend NEVER fail to entertain!!!

Dude this is freaking awesome... May have to build one myself

4:01 "Oceanside Beach" is a very creative name for an beach that is located at the sideline of the ocean. Wow! Much impressive!

Imagine hunting tuna underwater beating it's speed

Now it needs a carbon fiber foam filled wing

The wake coming off your goggles is so sick - you nailed it!

Myes, simply impeccable content yet again. And unequivocally, do put more engines!

i NEED the full "put more engines" song

You could try wrapping a metal mesh around the intakes to prevent some of the seaweed from accumulating

Streamline it closer to your body, they don't have to be flat on your back like that. You could set it up, so you can independently operate a left set and a right set to allow you to maneuver with just the jets alone. Id suggest a triangle shape stack. On your back; rough triangle spread out as flat on your back as you can without impeding your movement… A tight ⛛ on each side. Add a vertical stabilizer on the center jet on your back, approx. 3" tall. On your side center jet add horizontals at 1 inch or less. As for extending its distance. Figure out how to waterproof the charging port and a backup powerbank. 3D print a housing, perhaps.

Preston is my new favourite dude in RU-vid.. I love how he bought Autotune for RT outro and now is abusing the software in his videos. Love it

Put the engines on top of each other to reduce the drag and try to make a round shape with the middle engine a little forward to shape like a rocket maybe....!🚀

Too cool. Keep up the great work my man

If you make the jets diagonally like a zigzag line, then you have more jets in less area. which makes your jetpack more compact and lighter just an idea for ja future video like the Katjuscha rocket truck

Maybe a polka dot style intake cover rather than the slots? Instead of straight across your back try a V? Befriend someone with a 3d printer and make a cap for the top. Instead of 1 big airtank try like 3 smalk ones, one on each wing and then one in the center on your back? I love the joy in your videos

Congrats on 400K! 🎉🎉

I think if you made this a chest mounted jet pack to ride on top and positioned them into more of a "2x5 cube" you might have more success at controlling it. Basically a jet powered body board cos you could then mount in elbow rests and handles to hold onto

I would've removed the plastic covering the button toggle, then you can run a bar that goes across the buttons so they all get pressed at the same time. It would be easier to control the buttons that way. If you knew an engineer, they could even make a board that has a bluetooth to a chip that you can place on the board and synch all the engines to one controller, there are many ways to go about doing it, but the fact you're not an engineer and still made a sturdy build is very impressive. Great work brother

I think building this into a hydrofoil wing would increase stability and improve control.

As a self proclaimed engineer I say, DOUBLE IT

*the jet pack*: FEED ME SEMORE

I think the biggest obsticle to speed now is the resistance from your face basically smashing into the water. If there were filters on the intakes of the motors that could help with the tangle issues but they could get clogged as well.

Damn freaking badass! Just wait til goes commercial!!

Brother I just wanted to thank you so much I have been beyond depressed horrible time my life and I really needed some Jimmy up and make me laugh and your videos were savior for the first time in a long long time i laughed and smiled remember, last time I did I’m gonna keep binge washing. This is what I needed someone Brian sending my life to take me out of my depression in some way I have to give you the credit for saving my life don’t care about hanging out here but I was gonna be at the point where I was just gonna end it something got me on RU-vid and I saw your video somehow I don’t feel that way now. Thank you so much. Keep up the amazing your videos are something special, you definitely savd my life

I'm no expert in aerodynamics, resistive force is greater at underwater than air, hence like other comments said stremlined it, you'll achive the results guaranteed. keep up the fun! great video clip.

maybe you could add some air ballasts to help counteract the extra weight. It might help controlling your movement and be in less danger of drowning if you could be neutrally buoyant. You could use some empty 2 liter bottles and strap them in parallel to the engines without sacrificing too much hydrodynamics

@prestongoes add a wing type handle bar with all of the throttles on it and hold it out in front of you. It should help control and make it more streamline.

engineering student here, make models of ur engine setup with a model of urbody and add fins where needed and test it out and see how to stabilize ur swims with those

"The ballon dipper thing that kept happening" got me man 😂

I haven't seen a video creator exude so much enthusiasm in years. 😂😂😂😂😂😂😂😂😂😂😂 Its literally shocking my depressed system lol

Try doing some reprogramming in some rewiring To allow the motors to use higher voltage Then what they would normally use

Get all the thrusters closer together, maybe in a triangular shape. Tie off all cables together and route them nicely. My best bet is over the shoulders and inline with your arms. You need a pony bottle, though I would strap it near your centre of gravity like in-between your legs or in a ventral position (on your stomach) Lastly you need fins. Not only on your feet but some other system. You could put your hands down tight to your body a slightly flap them to increase drag on that respective side

this is the first video i watch from this channel and my first impressions are: it feels so cool and also you look like Jonas Strand

I love how they made a song out of people basically saying double the engines

Spacing them out is the best idea. Wingspan being wider means more water to push off from. Means more speed. Causing a bigger wake in the water. Creating a massive bubble to push off from. From behind you.also distributing the wait down to your feet as a stabilizer. Would help from the engines rising up to the back of your head. Needing a whole suit to keep in tightly in place.

Don't test that many engines in a pool, you'll crack your skull open!

You still need to work on your streamline in the water. The way your head and arms are positioned, olus the jet packs in a big square on the side...this is why youre getting diminished returns. Doubling the engines but not the speed. Tuck your head down, arms straight in front and squeezed by your head, create a good streamline. Make the packs more in a V formation with the point forward of course. A good streamline is a huge difference when you move through water.

Double it and put it on an Olympic swimmer. 😂

You should make an apparatus that wraps around the body to add more jet packs

My anxiety when he went really far into the ocean 📈📈📈📈📈📈📈📈📈📈📈📈📈📈

I would recommend larger props or even compressor fans if you want up power, also change to a small separate power source.

I would put the jets on a singler tube like structure(slightly buoyant) , throttles on joystick like handle, and a lever for your other hand that controls make shift fins. The bionic dolphin ride. More stream line, more speed.
