thumbs up if u dont know how u got from dubstep to mentos

[MUNTraiano]

you should have measured maximum speed and acceleration

[StevilTwin]

You A-holes with the ignorant jealous comments are the real Idiots! Minions like you need to surf sites just to post asinine remarks. I hope you eventually get a life of your own...Well, maybe you are just not capable? My bad…I shouldn't pick on the hillbillies...

[ariizrb26dett]

54 bottles of Coke Zero

324 Mentos

1 idiot! LOL

[ReleaseTheMonster]

@ariizrb26dett Correction... 2 idiots. And a cameraman.

[CruelMaple]

someone please submit this to mythbusters. i am to lazy to create an account on discovery . com.

[ReleaseTheMonster]

@CruelMaple I was thinking the exact same thing!

[SavaVeo]

damn what a waste of coke :( even more if that's Classique hehe

[joedsavage]

Guys are funny--entertaining.

[Solid33Snake]

He looks like Captain Kirk xD

[cameraguy38]

Good effort. I'm not sure that the Coke Zero & Mentos propulsion method is quite ready to take on the internal combustion engine but then again, the Wright brothers only managed 37 feet for their first powered flight. With a firm spot on which to stand, and with the right trajectory, I'm certain this could very well take you to the moon and beyond, though admittedly, so could a bicycle pump.

[heavymetalangel1989]

Better than Gas...

[popetmaster1914]

Idiots they spend more money and buying coke zero , that why the world don't replace gasoline and am not against future type of fuel inventions,but fox look this losers, they are 2 idiots and a lot of coke what's next a sandwich on wheels or yellow mustard for painting .

[MrWarcraft1000]

@popetmaster1914 you are a dumb troll. The views they got on this video alone more than pay for the coke 0 and mentos. 

[tcmLOG]

evo ko je mućkao kolu :)

[Posterdude95]

we don't need to use fuel anymore! :D

[dangerrangerlstc]

I wonder how much more distance you could get if there weren't so many leaks. I realize it's probably hard to get that 100% sealed, but all the loss of pressure there means loss of distance.

How much time did it take to build something like that anyway? Lot of PVC in there.

[eagle57ist]

@dangerrangerlstc It took us at EepyBird, 14 production days, over several month, to Design & Build the New Rocket Car . Half of the PVC Pipe from the old car was used . Half of that had to be modified to fit the New Car . Yes ! Lots of PVC in there . Thanks for the Question .

[PixelVonDix]

amazing.



[wordyeti]

I think you need to refine the venturi - that is, the opening at the end of the tubes. Perhaps you can even be a bit thematic about it - using a "Coke bottle shaped" choke to increase the pressure in the last few inches, to increase the speed of the ejecta and thus multiply the thrust? Or is that a bit too complex for some simple white PVC pipe?

[CIREM3]

Holymoly imagine all that my coke rewards points they got!!

[JuanRojas956]

and people in Africa die of thirst ..

[tylervw]

@JuanRojas956 Coke doesn't quench thirst, it's a diuretic.

[Gotyk994]

Hey guys, did you ever think about instead of using a wall behind the vehicle to give the car a needed thrust, use some Paddle wheel to spin off? I think therefore you wouldn't waste as much energy as you do when moving away from this wall...

Great job! Keep it up!

[DonaldB163]

Very dangerous... big oil CEO's see this and you're done for!

Awesome new fuel

[mummy2014]

Alternative fuel

[curtisludlow]

Just 327,410,526 bottles of Coke and you can go to the moon with that contraption!

[Saberx723]

@curtisludlow You didn't take into account the weight of the extra coke or that it takes more energy to fly than it does to roll along the ground. My calculations have it at about 10,872,228,381. Supposedly people buy 3 million a day. So every 10 years people buy enough Coke to go to the moon (assuming those bottles were the large size which likely isn't true).

[Stikafknaegt]

@curtisludlow And recycle the bottles!! Winwin!!

[tomesan007]

CRAZY!

[godbluffvdgg]

Being mechanically inclined; I would suggest taking the "exhaust" and recycling it with pvc elbows back through more mentos, then divert that "exhaust" from that. to the ground like a Harrier jet, point them rearward with beveled back ends 3/4 to 1 inch above grade. Also, reduce the 1 inch pipe to 3/4 inch at the end.

[slaverfangdog]

@godbluffvdgg I would suggest using classic coke.. it's just a better product.

[ghostrid3]

was that the tubes at end of video coming off or were those inserts to tubes to narrow and concentrate the explosion of liquid

[EepyBird]

@ghostrid3 We're actually using a simple piston mechanism. Each 6' tube attached to the bottles has a 6' rod inside it. The pressure from the Coke Zero & Mentos reaction pushes the rods out of the tubes, so we get 6' of really strong push off the wall behind the car. We're mostly coasting after that.

[ghostrid3]

@EepyBird Ok, that makes sense now. However, I was under the assumption this was a rocket propelled car, being moved the by force of fluids and not pushing a piston against a wall to push the car. Just sayin'

[generallzod]

hmmm this may solve our green energy fuel needs

[Nadirion1]

Wouldn't mounting coke bottles upside down help with propulsion, since you'd be expelling liquid, not gas

[4256573]

Why do they hate the polar bears so much? Don't they realize the huge carbon footprint created by such a wasteful endeavor? This prank was so unnecessary.

[godbluffvdgg]

@4256573 They must be doing something right the Polar bear population is exploding. Google it. Polar bear pop increase 400% since 2000. Global warming is a lie.

[mobohlen]

You need to use tubing that can expand and contract like an aorta so you dont loose all that power from leaks... Plus if the tubing is can expand it will be able to conserve that energy. Cheers

[VotingFemale]

You guys have way too much time on your hands hahahaha Go study the application of Bernoulli's law in the design of rocket motors and report back. ;-)

This will be the nutty liberals idea for the next " green power " that will fail LOL.

[chrisMcG17]

I knew i wasnt crazy as a kid wanting a soda powered car.

[kuladeeluxe]

The Challenge is set. Beat the record!!!. I would bet if you could harness all that energy, you could drive a Buggy a mile or so.

[USAredneck]

I was thinking this would be a good 'passing gear' for my Volt.

[EBenderTheRobot]

This is really stupid. I am embarrassed to have watched it all the way through.

[WilliamsBallMusic]

Nothing but thumbs up for this one, guys! Way to think out of the box.

[MyFriendLeonard1]

Wonder if you could channel all that fizz-force into a single chamber with a controllable release valve on it. That would make for a more sustained impulse ... maybe.

[pavelham]

The cluster of pipes reminds me of a pipe organ (lying sideways, of course) which causes my brain to wonder if a variety of different size pipes with little pipe organ holes in them (sorta like whistles, I think) would create a new kind of music?

[MB7classical]

@pavelham Ha! I love that idea. : D

[sLeepPastNooN]

two words:

[penguinistas]

2:20 You have afterburners.

[j00jy]

This is how NASA started.

True story.

[MyBigDing]

Days like this make me proud to be an American

[FlatFifties]

You need to put reducers on the end of each pipe so as to increase the peak pressure while at the same time extending the time that the pressurized coke sprays out of the pipes.

[ilusions4]

waste of coke much?

[ilusions4]

gay song... nice vid though!

[ilusions4]

gay song but video is good.

[flyboyustabe]

Why? What's the point? Don't you guys have anything else to do?

[whistledink]

@flyboyustabe How do you think ANYTHING gets learned or invented since the beginning of time? People doing things, man, people doing things.

[flyboyustabe]

@whistledink Oh, right. We're gonna "invent" something here by fizzing a bunch of cokes all over the pavement.....gimme a break, will ya hun? Just looking at the mess they leave behind is a strong clue what they're doing amounts to nothing more than mental masturbation. I'm embarrassed for them, actually.

[lifeisgood070]

Also might be a cool idea to think about optimum temperature for the coke and/or mentos.

Adding them all at once or in a time delay by bottle or by time delay per bottle (more than 1 mentos dropped in a bottle separated by a time).

& I think if you focused the pressure at a paddle type weighted flywheel connected to the wheels through gearing you would have a much higher mechanical efficiency. + you would have leftover inertia.

With 54 coke bottles there's no doubt you could break 1/4 mile.

[EepyBird]

@lifeisgood070 Thanks for the comments! We've been making improvements, including clamping down the pipes to reduce wobble, as well as working on the optimum temperature. So far, it looks like the warmer, the better. Our initial tests with a paddle/flywheel were not as successful as the piston mechanism used here, since a lot of what flies out is gas, but we should revisit that with what we've learned since.

[lifeisgood070]

The bends should be a bigger gauge than the pipe exit.

Need to figure out a new dropping method for the mentos so you don't lose pressure

Should combine all the pipes into one larger pipe to reduce fluid friction loss

Possible shorten pipe exit

Should have mounting brackets on the pipes to stop "wobble"

I'm assuming the coke bottles are open - what about pouring them into 1 vat? Then you could control the volume & pressure seal much better

Also thinner tires, but i'm guessing its too heavy

[BilWil1963]

Would it be cheating to use one tank full of DC and drop in a bunch of crushed mentos with the full explosive impact expelling through one jet like nozzle for optimum thrust?

[Cavindude]

@BilWil1963 , it is all the little pits in the surface of the Mentos that have been attributed to the excitement of the carbonation. Crushing them would negate that.

[kev1865]

HA HA HA.....That was FANTASTIC. The first time I watched it was with the sound OFF, so I noticed the "presentation" you guys did....it was the best part (high-water cover-alls....guy driving the car actually Sipping a soda....and all the other extras).

GREAT VIDEO !!

[thestudiosG]

now le entiendo

[MajorRugburn]

got retarded. if you want it.

[Pudzinator]

You would think they would have a better camera :P kidding haha but good job!

[Norridge722]

You guys! A Maine Triumph.

[Jmarsfan28]

what a waste of coke. Use the generic pepsi next time

[Politics4Dummies]

All this video is missing is Weezer.

[Politics4Dummies]

Drudge Report has a great sense of humor.

[703tomato]

Sneak in a downhill test track and you'll surely make new records

[PInk77W1]

i rode my bicycle 2750mi. across America in 30 days. I think i beat these guys, but im not sure!!!!

[greenbottle12in]

Perhaps some kind of magnetically operated Mentos dropping mechanism would work. You'd still be able to operate an internal valve of some sort to drop them, but without requiring a hole in the tubing for a mechanism to extend through.

[TheRealSKD]

Approximately $100 for 28 gallons of "fuel" to travel 239 feet. Hmm... Oh well, it was a lot of fun to watch! :)

[jimbo081]

Nice to know we have an alternative when gasoline runs out.

[jundude1]

very old video , watch 3D version here

watch?v=YuxqPuhLBZg

[BaN590DeR]

this is why you should buy coca cola ,,, not for drinking .

[tsiya2]

You need wings on that thing!

[erdiferik]

White people...

[tbone924]

@EepyBird would you go farther if you spread out the release to two or three pulls so that your thrust would happen more than just once? Or would three smaller thrusts give diminishing returns? Am I making sense? sorry, not sure on all the scientific mumbo jumbo :)

[EepyBird]

@tbone924 Most of the push comes in the first six feet, when the soda pushes the 6' rods out of the 6' tubes attached to the bottles -- we get more power out of that than out of the soda spewing out into the air. That being said, we are thinking about ideas like that to get even more power! :)

[BruceBoppoTiemann]

@EepyBird Oh, is that what those are. I thought half your tubes blew off, although I didn't see any soda going up, so it couldn't be that. The heavier (denser) those rods are, the more thrust - up until the backpressure is such that things actually do burst.

[1pasticcere]

I heard you today on KGO! That was a fun interview:)

[WeknowhoUR]

I don't think the record counts if the car is headed downhill on a slope. ;-}

[jk7350]

woooow first the moon now this ! go mankind, go !!!

[panhead1219]

I have a "Soda Club" machine, where I can add as much "fizz" as I want. Will that work with just water and Mentos', or does it need the caramel color?

[EepyBird]

@panhead1219 It doesn't need the color, but for some reason, it's worked better for us with Coke Zero & Diet Coke than with simple carbonated water. The soda may hold more carbonation for longer than seltzer water.

[rvndmnmt1]

@EepyBird Might work better because coke has high levels (but safe to consume) of phosophoric, carbonic, and citric acids. Might be the acid content working as a catalyst improving cokes yield over soda water. But I am no chemist. Just an armchair observation.

[jhhwild]

Now this is what I call an alternative fuel source.

[jjrakman]

gotta do a better job at sealing all the joints so you don't lose so much thrust.

[EepyBird]

@jjrakman Definitely. :) Holes for the trigger mechanisms (pins that drop the Mentos into the Coke Zero) releases some spray. There's so much pressure involved, we had more spray released than we hoped for.

[TEHTYMEKITTEH1]

Dont you lose a lot of the thrust in that bend at the bottle?

[EepyBird]

@TEHTYMEKITTEH1 We initially tried to have the bottles on their sides so that there was no bend, but we couldn't get the trigger mechanism to work well. But our tests suggest we're not losing much power from the bend.

[TEHTYMEKITTEH1]

@EepyBird  I see. Thank You

[zintradi]

@EepyBird why don't you try a new system where you ditch the bottle, put the coke in a chamber, dump the mentos in via a butterfly valve (so the chamber reseals after mentos delivery) then direct the "propellent" through a turbine that turns the wheels via a transmission?

[EepyBird]

@zintradi Nice idea. If we put it all in a chamber, we'll lose a lot of carbonation as we pour it in, but we're experimenting with ideas like that. And on the unscientific side, we do like the look of all those bottles.

[BlueSun1971]

This was so funny. At least Coke Zero is less sticky than diet or the original. I mean if you're gonna wear it.

[SelfEnterpriser]

Perhaps VirginAir could use this tech for the upcoming space flight? I won't go on the flight, but I'd be at the launch site with my 64 oz. cup collecting the manna from heaven.

[Wildflower90640]

Truly a Wright Brothers moment!

[bryonlape]

With a better seal on the bottles, the car could go further.

Well done gentlemen! Very entertaining and very funny!

[eagle57ist]

I can't wait to see where this New Rocket Car takes EepyBird this time .

Building it was Great. Using it will be Awesome . Big Thanks

[chrishiner]

So, about 1.9 ft/liter?

[meegul304]

@chrishiner That would not be entirely accurate because there is a minimum amount of liters needed to overcome static friction, but in theory, yes.

[tonydunc]

how man more refinements before you are ready for Indy or Daytona? You can factor in that you don't have to go as fast as those cars because they will be sliding on your propulsive discharge

[Power1Productions1]

At 2:07 you can see a little flash. What is that?

[eagle57ist]

@Power1Productions1 This is Big Dave from the EepyBird Rocket Car Pit Crew. The flash you saw is from My camera taking A picture from the side , as the Rocket Car is Leaving the Blast Wall . Thanks for the Question .

[staffordgreen]

yeah!



[gregdeocampo]

Love the music!

[masturcheeef]

Pretty damn awesome!

[FireFighter214]

Does coke zero work better than diet coke?

[EepyBird]

@FireFighter214 They both work really well. The key is to use diet soda -- it's got more fizz (more power!) and with no sugar, it's not sticky (easier to clean up!).

[kaimelis]

0 to 4 in 19 seconds!
