How did you separate the baking soda and citric acid? Please reply!

[antigravityresearch]

The baking soda and citric acid are both dry powders, so they can be mixed together with no reaction. However, this mixture must remain separated from the water in the syringe. The water is at the bottom of the syringe, the mixed powder is at the top in a tiny perforated basket lined with kleenex. Put a drop of dish soap in the water to break the surface tension so that it can run up into the chemicals when the rocket starts decelerating. K.

[TheXrader123]

can you do a tutorial on the recovery system?

[TheXrader123]

what are you putting around the bottle is it black string?

[gagomand]

Nice job, keep trying and u will get to 1000 meters in no time

[tacotimeism]

hey would u mind making a tut?



[nikokaleo441]

hey mr. smith



[fuckalotopussy]

my home made one can go almost this high. all u need is some weight and that shit flies

[crimsonshadows1]

why not use helium to compress? then you get double lift :P

[sonofagunM357]

Amazing

[creamojohn18]

men ?/ can i ask why are you pulling something??

[antigravityresearch]

To launch the rocket I pulled a string. This released the filling hose from the nozzle so the pressure in the rocket could push it out. Ken S.

[Sauron000]

could you make a tutorial how to build the connector of the bottle with the plumb?

[coolaussie2009]

hahahahahahhaaha im at school

[3dannsiki]

Do though the jet time is too long for the water rocket?

What do you jet?

Could you teach?

My best regards.

[tevada2010]

how to add baking soda and citric acid powder in the top of syringe ? it is powder.

[TheSparcoss]

1000 psi impossible ! the bottle explode at 180/200 psi 912 feet? fake !

[JonathanKlemetz]

How did you calculate the altitude?

[camachit]

tio esto es penoso

[MegaLordofthestrings]

it looks like a mortar when its coming down

[andrewlee81919]

5:45 hes injecting steroiods to make it stronger and go further lol

[TRTtherocketthing]

why do you need to make it BEND ????

[antigravityresearch]

The idea of bending the ring fin structure came from an earlier failed flight where the structure bent accidentally, and the rocket flew horizontally just like an airplane. This rocket was supposed to fly straight up, then transition to horizontal flight on its way down when the ring fin structure bent. No parachute would be necessary. Sadly, the fin structure bent on the way up (see movie part 2). Kenneth S.

[samhines014]

@antigravityresearch do u have any idea how to do this ? like pop bottle on a horizontal flight,. (must not leave the ground) ?

thnx

[antigravityresearch]

I use a mounted electric handheld drill to turn the bottle at low speed, and control the speed by a foot pedal. The carbon fiber filament is pulled through a liquid bath of polyester resin with hardener added, and the fiber is moved by hand back and forth beside the spinning bottle. In this way you can wind axial, radial and helical layers. It takes a bit of practice, so plan on trying a few bottles as part of the learning curve. Ken S.

[AzpeMan173]

You should put a parachute on that

[applesweeter]

What did you put into the bottle? Water?

Please tell me!!

[antigravityresearch]

A mix of 30% dish soap and water, with compressed nitrogen at 1150 psi to provide the power. Ken S.

[waamll]

what is your nozzle diameter?

[antigravityresearch]

Nozzle diameter is 0.136 inches at the throat, and about 0.44 inches at the widest part of the cone. KS

[waamll]

@antigravityresearch

tnx!!

[strawberryxin]

what is your pressure??

[antigravityresearch]

Pressure in the bottle at launch is 1150 psi.  KS

[areyouvicious]

when the bottle drops down someone should've yelled incoming haha

[lolstring909]

HOw did you release the bottle at a particular pressure? and also the design?

any suggestion if you are only limited to 60 psi with water and air only?

[antigravityresearch]

A spring wire clip held on to the nozzle. I pulled a string to release the clip, and then the pressure in the rocket pushed the filling plug out.

At 60 psi, use a nozzle size of 0.180 inches diameter, 200 ml of 20% dish soap and water as the fuel. Make your empty rocket as light as possible (60 grams max.) This is similar to the AntiGravity SkyLab rocket kit, which flies to about 250 feet altitude. KS

[lolstring909]

[kno3nitro5cole]

that is not the world rocket flight

[antigravityresearch]

Do you mean the water rocket world record, or do you mean the pop bottle rocket world record? The water rocket world record is higher, somewhere around 2000', but they didn't use a pop bottle. This is the pop bottle rocket world record. KS.

[buzznandes]

What is the model/mark of the compressor you briked at 430 psi ?

I am searching for one.

[projektforlife]

how does your nozzles and fire mechanism work? i use gardena

[buzznandes]

I never knew the nationality of the dude. Is he german ? Looks like by the accent !

[erikw789]

erikw789

where do you get hurricane tape i checked ace and home depo

[RaverLegaecyClan]

is that only water nothing else?

[mbunds]

1120 PSI? Awesome! Bet it took a lot of trials winding that support mesh!

[cursedreject]

wow haha

me and my partners broke the record for our water bottle rocket. our teacher timed us by the last part of the rocket that lands and we had a parachute shoot out of the rocket. it eventually floated out of sight and he marked it down for 2 minutes and 15 seconds even though it was still over 100 feet in the air (the parachute)

[alejorapmclc]

How much is it ??????

I need one of these

Thanks

Wait your answer

[WithStandThePain]

Any suggesions on a good fin/wing design for my basic bottle rocket?

[antigravityresearch]

Short of getting some excellent fins from AntiGravity Research. you can make great fins from polystyrene foam picnic plates. Make three rectangles about 3 inches by 6 inches. Mount them to your rocket as low as possible, usually around the neck or cap of the bottle. You can use hot melt glue if you don't mind repairing the fins after each flight. AntiGravity fins mount using elastic bands, so they don't break on impact with the ground. KS.

[somedaytheendwillcom]

I made one in high school, and it went 387 feet and I had a rotar system for a recovery system. whats your altitude?

[antigravityresearch]

This one went 1242 feet up.

K. S.

[mikoji123]

if you stil making this world record, try to beat it like 1300 feet so no one can beat your record

[LuisEn2890]

woooow!

[srtmma]

SWEET sax solo lol

[antigravityresearch]

Thanks!  Ken S.

[masharcool123]

can you tell me how you realeas your parachute in mid air?

[antigravityresearch]

There is a syringe at the top of the rocket, with baking soda and citric acid powder in the top and water in the bottom. When the rocket stops accelerating, the water runs up into the powder and starts a chemical reaction releasing CO2 gas. The gas extends the syringe, lifting the nose cone and an elastic band pulls the parachute bundle out. KS

[antiswattt]

that parachute system is pretty cool (: btw instead of that fiber wire thing (which i guess youre using because its strong) you can use aluminium tape.. its really thick and .. just thick and sticky or electrical tape (also very strong) but im not sure if you already did use that? (:

[ChuckManiac]

Ah, that's a very cool chute deployment system. I thought you used the simple method of just tucking end the chute and strings in the front. That's what I do with mine, but of course it's a lot simplier and low altitude compare to yours.

[shitpickle1128]

add a explosive top to that and wait for it to come back down :D

[buendnerchopf]

what is that black string????

pls reply!!

[antigravityresearch]

I presume you mean the carbon filament.

It's got 24000 fibers in it and you can get it from Toho Carbon Fibers. KS.

[Skydivingkittens]

Why soapy water?

[antigravityresearch]

The water foams up when you fill the bottle with air, effectively mixing the water and air in a compressible slurry. This raises the center of gravity making the rocket more stable, makes better use of the energy by eliminating the water-first-then-air inefficiencies, and allows use of a delaval-type expansion nozzle to accelerate the exhaust as much as possible. KS

[burn552]

lol love the voice ahhhh now we are geting some where

[tomolonotron]

the music's well annoying

[mongoose96]

ahhh now we are getting som were

[NoNamer123456789]

That´s cool. 5\5 Stars

[jeffthedoomknight]

this is amazing! I saw the dish soap tip in your other video! great idea!

all I need now is some carbon fiber :)

[druman50]

i did one of these in 7th grade at 80-100 psi and 500mL of water and it went really far and high

[indianmaluji]

i did one in highschool @ 150psi with a coke bottle went 100 something feet

[MuckyMcPuppy]

Absolutely!

Apart from fulfilling an important role with regards to testing the best way of wrapping the carbon fibre/Kevlar filament to achieve maximum pressurisation potential, all kids love to make something explode! ;-)

And at these pressures, it's a serious bang!

Hence the distance kept and safety precautions...

My question is: where can I get the carbon fibre yarn? I can only find pre-woven fabric or mat...

[roylepatrick]

what the HELL!? i made one in grade 3 and it went like 10 meters. how the hell did you do that? is it a pressure hose? or compressed air?

[whamfan87]

Thanks for throwin' in a little Peter Sellers! Great job sir, not that my opinion matters, but amazing work. Thanks for posting!

[waynedavisband]

good use of enginuity
