WARNING:
Rockets are not toys, and this project really should not be duplicated. This video is mainly for educational and demonstrational purposes. If you’re going to attempt it anyway, I highly suggest contacting local rocket clubs to become familiar with local laws, and how to stay out of trouble with the FAA, and avoid hurting any people or property. Playing with unstable rocket motors could result in serious injury, property damage and/or legal ramifications. Use of this video content is at your own risk.
You should be aware that misuse, or careless use, of rocket propellants or ignition of an incendiary or explosive material may not be legal in your area. Check local laws and inquire with local rocketry clubs on how to safely make and launch sugar rockets.

Project Inspired By:
A few comments from viewers suggesting to combine two previous projects to see what would happen. The delay mix and ejection charges came from the book “Easy PVC Rockets” by Jason Smiley. (bit.ly/IBEasyPVCRockets) If you check out the link, please share the love and let Jason know that Grant Thompson sent you. :) Thank you!
My friend NightHawkInLight also has an awesome video on a different method of making a cored rocket with black powder. You can see that here: bit.ly/IBBPCoredRockets
Project History & More Info:
In a previous video on how to make sugar rockets (bit.ly/SugarRocket) I promised to show how to make a delay mix and a parachute ejection charge.
I would caution anyone wanting to launch a duct tape rocket without a parachute to take every precaution imaginable. These are not toys. They can light things on fire, and fall down on peoples heads, which I imagine could cause serious injury. You may need permits, or only be able to launch these on special experimental launch days with local rocketry clubs.
My launch was out in the middle of the dessert, miles and miles away from any people, property and anything flammable. Safety precautions were in place in case anything went wrong.
I wanted to demonstrate what happens to a rocket without a parachute. You can see it basically becomes a lawn dart. And while rockets should never be launched in an area close to people, property, or highly flammable materials to begin with, they really need to have a parachute to retard the descent rate to minimize potential damage.
I made another rocket with PVC, and a parachute from a big black garbage bag and static tested the ejection charge multiple times, with 100% success.
I didn’t have a chance to launch the rocket to test the charge while air born, but I’m extremely confident there is plenty of power to push a parachute at apogee.
I’m thinking about making a project video showing how to make a rocket with a parachute from scratch, so if you’d like to see me do something like that, leave a comment letting me know.
Once again I want to reinforce that playing with rocket motors could result in serious injury, property damage and/or legal ramifications. I highly suggest contacting local rocket clubs to become familiar with local laws, and how to stay out of trouble with the FAA, and avoid hurting any people or property. My launch was out in the middle of the dessert.
Whether or not you’re interested in rocketry, I hope you learned something new, or were inspired in some way by my experiences.
For all my friends and followers in different countries who don’t have access to these materials but still want to build rockets, watch for my matchbox rocket video coming next week. I promise you’ll be able to build this next kind. :)

Your amazing but how do I learn to do all of this and not let it fail
I always try some of your projects when I can, and the results are always positives, keep this up.
Grantthompson you are awesome
i live in suomi finland and i dont really have so much of thoes stuffs
Nice
Rest in peace youtube science legend.
Marcus Cain what
He's dead 😭 -_-
If there was a salute emoji everyone would be using it
@@zazonf1832 he is dead
Really
grant is still alive, but in our hearts. rest in peace dude you meant a lot
I have been doing homemade rockets with my eighth grade class for the past 23 years. We use the already prepared rocket engines, but the rest of the rocket is made entirely from scratch. We use cardboard packing tubes, Easter egg nose cones, balsa or basswood fins, and parachutes made form trash bags and monofilament fishing line. I would really be interested in your spring video on homemade rockets.
Dang that class been with you for years
i took that class in 8th grade. metal shop. why we were making rockets, i dont know. but it was alot of fun.
Hmm...You just reminded me that my explosives manufacturing license expires tomorrow. Maybe I'll renew for next summer.
Lol
Happy Birthday Ben!
у тебя тоже крутой канал!
Magneto! Thank you kindly, happy Thanksgiving!
Does that mean you've got some manufacturing videos coming next summer?
This dude single-handedly inspired hundreds of creators
To keep the homemade rocket fuel from absorbing water, keep it in an airtight (really airtight!) container along with one or more silica gel desiccant packs.
Sadly the cops in my town don't have a sense of humor

Kinetic sand is really cool but it's also kind of expensive. Could you show us how to make it ourselves. I think it would make a great DIY project.
Great idea!!!!
some research told me it's 98%sand and 2% Polydimethyl siloxane, which sounds pricey
Eric Revollo It is indeed sand treated with a special polymer. Perhaps grant nows a way to create sand with similair properties for cheap.
use cat litter sand.
Thank you soo much for posting a new vid about Candy Rockets! because of you, I've bought all the mats for making the motor and have been impatiently awaiting your newest vid. though you have been busy, I've done a lot research and commend you for your truly sound E-45 vid! because of you, I've been having great, safe fun! everyone in my house thinks I'm a rocket scientist now!!! Thanks for the delay info, I couldn't figure that out.but I did notice the humility is truly an issue. SAFETY MESSAGE Toaster ovens can be used outside!!! this can save homes... especially if kids are attempting this. please be careful, everyone!
Georgism pfp?
Time to make homemade RPG
R S F Yeah !!!
Thats what i think the hole time!
It's... not fun. I've tried it (with smaller rockets ofc) and that stuff kept exploding
Never trying that again
Edit: I used 1/2 A class
Worked like a charm, grandma didn’t stand a chance
@@aisforanimate4703 for real?
Yes!!! Bring on more rocket projects... the simplicity of your designs and videos makes the learning process fun and quite unique for young and old alike. Also, would especially like to see a follow up video on your solid fuel rocket motors and how you put the sf rocket together from start to finish. Keep up the great work and keep the videos coming!
Awesome! In case you're not aware of them, you can buy keychain cameras fairly cheaply and they may be light enough as payload. Would be good for shots from the rocket. Looking forward to next week's how-to!
0:50 Dem aerodynamics tho.
Awesome!
This Planet Seriously Needs More People Like You Grant, You're A Legend!
And Yes, Rocket With Parachute From Scratch Idea Sounds Wicked!
Yes! please do more of these rocket videos! I used to build model rockets all the time when I was a kid. I even swapped out some of the motors in the rockets...we never did find the last one XD
Btw you can buy pure grade potassium nitrate for only $10.99 a lbs at Walmart online! The sugar you need to is also available.
black powder is sold at gun stores...
This man was a legend, rest in peace knowing you helped me achieve my dreams
AWW YEAHHH!!! Water rockets are next. I loved playing with them as a kid. Not sure what new things people are doing with them now. Pretty sure there must be innovations for those things by now
Oh and keep up the awesome work, I think I speak for us all when I say we appreciate your hard work, money and the time you invest into these videos. Thank you
0:37 yeah a "paper rocket" my ex girlfriend had one of these too :D
OMG
oh shoot did you break up with her
I think I get it
1:45, he had that foundry all along! HE MADE US WAIT A YEAR!
Doesnt look that pretty anymore though
I just wanted to say thank u so much for your fun easy and cheap videos because when I go to Seattle to see my brother we r always looking for fun things to do together and we both love crafts and we saw one of your videos by luck and now when ever we r bored we just look up our favorite, grant thompson.
You my friend, are a bonafide genius. It's one thing to understand a concept, let alone applying it AND recording it for others to learn from. Learner, Teacher demonstrator and artist. Congratulations and Thank you for making these videos.
I would like to see more rocket videos :). Cheers for the hard work!
Awsome video.....I am looking forward for the rocket video with parachute ejection charge.
Your videos are just plain awesome man. Thanks for taking the time to do them! I think a video on an effective parachute would be really helpful, I think most of us will have trouble finding a place to even do this, much less have the time to test different parachutes....lol. Thanks again!
Very nice! I remember when I was young and made sugar rockets, I used to heat the sugar and the sodium chlorate to temove the moisture,, I then grinded them separetly into a very fine powder and eventually mixed them thorougly. And what a difference !
Can you show a clip when a rocket is launched with parachute?
I wanna see to
I was disappointed that he didn't show a parachute rocket? :(
Noah hughes my2
Its cause it probably failed no matter how many times he tried
Alright Grant, my dad and I have been making E45 sugar motors that you made in your two videos. One Problem... We had a test bed, and it was too light for this powerful motor. Could you make a video of how to build a rocket with a parachute for the E45 sugar motor?
Nick Lang he did
Nice video, and YES I would love to see an entire scratch rocket!
That is really cool how you made the ejection charge and from what I can see it works very well!!! Keep up the good work. One of my favorites that you did was the solar scorcher I got two lenses both are linear lenses but the one I took the side with the linear grooves and sanded them out and will polish the back till its like glass then it will become a spot lens
Very cool Grant. Yes please show how to build a rocket and parachute for your next video. Thanks
REST IN PEACE MAN!
You're Amazing exactly what I needed to know. All videos show lightening them off but this is the first I have seen that made sense to me stand. Thank You and my grandkids thank you
Love your videos!! And yes I would love to see you make a rocket with a chute from scratch! Did I mention I'm a huge fan!?
i wanna see a giant foam airplane modified with on or 2 of these. with maybe some rc controls.
I think it will go 9/11
That rocket at 3:46. It looks awesome! Can you tell me more about it?
man!!! i love ur videos, especially about rockets, waiting for more of those!!!
To my fellow Brits, the three ingredients for black powder are easily available on amazon.co.uk, these are Powdered Charcoal, Sulphur and Salt-Peter (Potassium Nitrate). Please mix responsibly ;)
Someone should attach a camera to it and have it record while in the air.
Now theres an idea...
Adding weight to the front is actually helpful as it shifts the center of gravity farther forward from the center of pressure. the theory of stability is that the center of pressure should be the distance of one rocket body diameter behind the center of gravity (1 caliber). any closer than that and the rocket will become unstable. if the center of pressure is forward of the center of gravity, the rocket will be really unstable. So, my point is, the weight will not negatively affect the performance of the rocket, however what may be affected is the aerodynamics.
***** Oh no, im just saying that i finally found someone with similer thinking if you want to put it thatway, sorry if i offended everyone in my last comment.
yeah !
but the camera wod brake
Grant Thompson - "The King of Random"
You can use ejection charge to build a 2 stage rocket :D
sorry but hes not alive anymvre
@@unkkid2967 I know, can you read read? I've posted it 5 years ago.
@@KRewolucja He can read, just not very well.
"Dean Borchert" - BP also comes in 4F (for priming flash-pans on flintlocks) , however, the substitute called "Triple 7" is has slightly more power, makes less smoke and is cleaner/leaves less residue.
Protect your parachute or streamer from the heat of the ejection charge with wadding, or release it with a mechanism triggered by the ejection charge. For really big rockets, an umbrella with the hardware removed can make a really strong parachute.
rip grand Thomson
What happened ?
charan charan he passed away😔
@Nik Reynolds rlly ?!
@@tunisianpartisan1080 sadly
well here in germany you can't get black powder unless you actually have a pyrotechnician's license...
Ow.. I just took it from some old fireworks :d
Element Finland mh could do that, but technically you're also not allowed to open up fireworks without a license :D
well nobody's gonna find out.
OH HI THERE BND! NOTHING TO SEE! XD
In Deutschland ist eher das Problem, dass du kein KNO3 erwerben kannst :(
TheLuin9 kaliumnitrat ist aber relativ leicht herzustellen.
vielleicht mach ich mir ja mein eigenes schwarzpulver, mit blackjack und nutten! :D
straikychan lol did you say at the end with blackjack and hookers cause thats what the translate says
Hi Grant you should totally make a video of how to make the rocket with the parachute! Keep up the awesome videos!
empressive, I cant believe the power behind this litle tube!. But really its very hard to find stumper mover in Lebanon, and even the black powder.Thanks for this video!!
Why not try building multistage rockets next? The ejection charge on the first rocket motor should be able to ignite a second rocket motor.
I dont know if you still want the answer after 6 years but if the rocket lose the stability and start to turn to the side, then that will be a problem
“Lawn dart” 😂
Anxiously waiting for your video where you make your own rocket from start to finish with the suger rockets.
I would love to see a video on a rocket from start to end! Great video as always.
You should send a rocket with a parachute
What next? How to enrich U238?
then the first step is building an uranium centrifuge
@@tesseract8033 no the first step is obtaining it.
so is it possible to use the parachute release to launch a nerf dart out of a tube of pvc pipe? like you would load the dart into a pvc pipe then load the sugar motor into the pipe behind the dart and light it?
Homemade rockets with a parachute? That sounds awesome! I'd love to see it
4:41 YESSSS!!!!!
Crap. I tried to prove you wrong about how high it flew, but 8 seconds accelerating at 9.81 m/s is 353 meters, or aprox. 1000 ft.
ish thats a very rough calculation.
How do you calculate this?
@@gemsilog9157
I think by this way.. (calculating the falling time after burn up as 8 sec.)
(9.8×8)+(9.8×7)+(9.8×6)+(9.8×5)+(9.8×4)+(9.8×3)+(9.8×2)+(9.8×1)
=352.8 m
~353 m
Mi viejo, mis respetos que gran conocimiento tiene. gran aporte, saludos desde Monterrey Casanare - Colombia
The new project of your own rocket sounds pretty cool. I'd definitely watch it.
I wanted to see the one with parachute :(
Thanks for not using imperial metrics!
At the end of the video, you mention 2 things: a scratch made rocket with parachute, and a version of these engines that work with Estes...I would love to see both!
Maybe the moisture in the potassium nitrate could be removed by pulling a strong vacuum on it. A little safer. I really like your videos and thank your for all of your great efforts. I'm very grateful.
should have strapped a go pro on there
That would have been awesome, but might be too heavy.
No not really did you see that thing fly, just make sure every thing is balanced and you are good to go .
not enough thrust, need cluster or thicker pvc pipes
peter kao normal weight of a normal go pro is 8.something oz. that's less then 1/2 a lb. there is more than enough thrust and more then enough speed to get the go pro WAY UP and still only lose like 30 or less feet
alex accosta But the weight and air resistance would slow you down.
where do you buy that bottle of black powder?
+darkdancerman Depends on your country. If you're in the U.S., check with a local gun club. People buy it for their guns.
Gun shops typically
a gun shop will probably have it
potassium nitrate, sulfur, and charcoal.
+grant Thompson it's a good rocket but it is only a 2 stage rocket if you are in America you are allowed to make a six stage rocket by adding another two two more time delays in between two more white mixes
well presented and very interesting. i have done some rockets wen I was younger using liquid and gas as fuel the solid fuel looks a lot safer method as some of my gas attempts went up in smoke.i am interested in your up and coming rocket building video keep up the good work
RIP TKOR
alternative for black powder?
There is a lot of explosive sold to the public... Its around the end of the year.
I like your videos. I make BP rockets and have a sugar rocket motor kits I bought on eBay. I've been using the sugar fuel as a delay in my bp rockets and works great. I've made sugar rockets by ramming the fuel the same as I do the bp ones and they work great but I've only made small ones up to 1/2". Dia. I add a bit of red iron oxide ( rust ) fine powder. And it makes it more reactive. Wander if you can do the same with your method of melting the fuel. It is a lot hotter mix. Would like to share making helicopters with the sugar fuel as well
What kind of pipe do you use to hold the propellant? PVC pipe ? Is that thick ?When I was young I used sulfur (S) & zinc (Zn) as propellant : awesome. Tanks for the video !
Could you please make a video about how to create black powder at home?
***** racist
***** I was talking about your reply
grant, do I have permission to use this for science fair?
please?
Leith Balson did u ever use it😂😂👌
This is an important message and pls reply
Can you tell me which rocket goes further this one or this one ( how to make sugar rockets ) it is for my science exhibition .
And what is the use of delaying the rocket.
This man is bloody amazing!!! So fun. I'll get to be a kid again
Or make a multi staged rocket
here's the world distructor
first it was for fun, then world domination. classic.
+Ken Reinhart
yup
That's what I'm trying. just make the engine without the delay
+coastermania17
it will esplode. good idea
♥️
HI Grant ,
Actually we have tried to build a sugar rocket from the past two days .....
'But as soon as it launches up in air it tips down or pitches down ...Can u suggest any improvement ...Will be very helpful..thanks.
i saw the sugar rocket video and told my physics teacher and she is on bored but we need to have a parachute so this this video helped me with the ejection charge thanks. if you have any ideas for a parachute in are rocket appreciated.
Whoever is watching this in 2022 ur insane
seriously you can buy black powder in the us?!?
Wow you can build bombs... for self defence.
I think you could kill more people with a gun than a black powder bomb.
softrockification Yea but bombs are more fun.
You can make black powder in your home, so why not?
Black powder is a poor bomb making substance. You will essentially just make large firecrackers. There are many better chemicals that can be made with in-home chemistry and supermarket supplies if you know what you are doing.
y-yes self defense..
I'm glad I got to do this as a project in school!
In my experiance i found that replasing the suger with charcole increases power emencely becouse sugar is just an impure form of charcole. And if you make the rocket ignite from the top instead the bottom it also incraeses thrust
you americans would rather say 3/32 of an inch instead of using the easy, simple and majorly used metric system.. I think it is sheer arrogance. there is nothing for lower than an inch and there is nothing in between feet and mile. 1 mile is 5280 feet. it makes no sense. same with ounce to pound, ounce to gallon. why america why..
The english system was used to win ww1 and ww2
I would like to change it but majority rules.
So just because you guys use means we are forced to use it just because it is easier.
between a foot and a mile there are yards and chains.
Honestly it's how I learned to measure things in school and attempting to use your system is difficult because of how I was taught, not arrogant just educated poorly.
Grant i joined yesterday and ive almost watched every 1 of you vids!!!! Stay awesome and keep making awesome stuff
He is deceased!
Hey grant love the video this looks epic.
I was thinking that it might sound crazy but could you use the ejection charge to eject a smaller rocket and kick start its motor sending it double the height.
thanks :)
Hey Grant, I'm a big fan. I've seen all your video's. Can you make a video of a sugar rocket with a lot of black powder or aluminium powder at the top, so you get a nice light flash in the air, like a real firework rocket
yoo i really like your videos!! and i see you use a lot of stump remover. I live in the Netherlands and we dont have stump remover in our stores. So my question is do you now something that wil alsow work but that's also available in my countrie?
thank you very much
Hey Grant have you tried using the rocket fuel mix for the ejection charge ? I'm rebuilding an old Estes Optima to accept this motor , never flew very good on a D
engine anyways.
Would the charge at the front be powerful enough to create a multistage rocket? As in using the charge to separate the lower stage and ignite a second motor.
Great VID, but yeah would like a vid about building a rocket from scratch with all the bells and whistles on it. :)
Grant Thompson - "The King of Random" Hey, I was just wondering why you use the delay mix on top of the white mix. Is it so that the white mix doesn't blow out the blackpowder too quickly? Or is it so that the rocket has time to level out a bit?
On the duct tape rocket that u made couldn't u use the aluminum tape used in the matchbox rockets instead? Or does it just not withstand the pressure? Also I'd LOVE to see how to make rockets without Potassium Nitrate so I can do it myself! Thnx a lot for some other ideas too. :D
You know i really like your rocket videos, and i was curious. would this make a good engine for something like an Estes rocket.
I've used a vacume chamber to dehydrate my chemicals if they get to damp and leave them under vacume for 24 hours, Warming the chamber a bit helps too, around 100deg F
Hi! so, after dry the KNO3 in the oven it will not get moissture any more? or it just will take more time to get it?
Thanks!
*I don't get where you put the parachute to make it eject? And is there something on the end of the parachute that you put in the other end of the rocket motor? Also how does it eject and how does it push the cone on the top of the rocket off?*
Hey Grant Thompson I really like your videos me and my dad do the kind of the same thing we built the Jacobs ladder just like you the neon transformer it worked really well and try to put it on 240 V it will work a lot better in the archer bigger
I was just getting into making my own rocket engines with the kids when you put this out. I've burned through 4 or 5 engines without getting enough force to deploy a chute. The energy seems to be going out the back with the rest of the fuel. I've tried a slightly bigger and slightly smaller drill bit to bore through the clay to the delay mix. I hate to just keep adding more black powder, but maybe that's what it will take. The rocket I've retrofitted is 30" with a 24" chute. Any tips?
