WARNING:
This video is only for entertainment purposes. If you rely on the information portrayed in this video, you assume the responsibility for the results. Although sugar rockets are the slowest burning of all rocket fuels, this project should not be attempted without adult supervision, proper permits, adequate training, and at a location far away from people, property, and anything flammable. Misuse, or careless use, of rocket propellants may result in serious injury, wildfire, and in extreme cases, death. 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. Have fun, but always think ahead, and remember that every project you try is at YOUR OWN RISK.

Project Inspired By:
A previous project on making Sugar Rockets (bit.ly/RedneckRocketry). I wanted a way to lock and load them into a homemade rocket, so they'd eject a parachute in a way that was light weight for the rocket, but still safe.
Project History & More Info:
I'm really excited to share my passion for building and launching rockets with completely home-made equipment. In my opinion, it's the best way to learn about how rocketry really works.
In a previous project (bit.ly/SugarRocket) I made rocket motors using PVC, sugar, kitty litter, and stump remover.
They worked so well they made me want to design a rocket they could be used with, and my friend Ritchie Kinmont with www.sonicdad.com was instrumental in making that project actually happen.
I made this tutorial to be a more comprehensive sugar motor tutorial, going over all the things you'd need to do to make a successful motor that will work with the "Randomizer" rocket, and addressing some of the issues and challenges I've faced in the past with failed attempts.
The 'Screw-Lock" version features threaded PVC risers, that allow the motors to quickly be changed, for faster turn-around times, and they have built in ejection charges for popping out the parachute at apogee.
I played around with ejection charges in the "Redneck Rocketry" video (bit.ly/RedneckRocketry)
I realize most people aren't very excited by building rockets, but for those who are, I hope you feel the same sense of wonder and awe as I did in building this series.
Most rocket clubs won't let you fly sugar motors, except on special experimental launch days. However, the “Randomizer” rocket can also be used with commercial “Estes” D12-3 and E9-6 black power motors. So if you go with those, there's a good chance they'll let you fly your rocket at any club launch.
The rocket can fly over 1,000 feet high, and depending on the winds, can stay in the air for around 5 minutes while it floats back to the ground, so it's important to be super cautious where, and when, you launch to avoid doing any damage.
Rockets are not toys, and this video is mainly for educational and demonstrational purposes. If you’re going to attempt making a rocket yourself, I highly suggest you check local laws and inquire with local rocketry clubs on how to safely make and launch them.

[@CastilloDelDiablo]

I used to fly Estes rockets, I bought one that was about 4 feet high and was said to reach 350ft, I thought I could do better. I designed a 1st stage that would hold 5 "D" Estes motors, two firing first, then two firing when the 1st ones burned out and finally igniting the last single rocket when the 2nd rockets burned out. While designing how I would get the rockets to chain ignite my friend calculated the dynamics of the flight. He came back the next week suggesting I should read his calculations before going any further. His calculations came to a max speed of Mach 1.2 and 10,000 feet high! I decided that needing CAA approval to fly a balsa wood and cardboard rocket probably wasn't a great idea and scrapped the project.

You are doing what we did as 14 & 15 year olds 35 years ago. We discovered the benefits of incorporating black powder into the chute discharge as well as the stage separations. We made a 15 foot rocket with over 30 motors in various stages. We didn't know if it was successful because it went so high we could no longer see it. After a few minutes we spotted the three big chutes indicating that everything went as planned. I miss those days. After incorporating some black powder into launch, stage separation and chute deployment we went to a 0% failure rate. Before that the success rate for 100% everything, was at about 85%.

As I have been ramming my own engines for some time, I have a couple of tips on this. 1. Add a pinch (about 1/16 of a tsp for your quantity) of red iron oxide. It acts as a catalyst to enhance the burn rate and increase thrust. 2. Place a piece of masking tape over the bottom of the engine. It helps to contain the clay. Pull it off just before drilling the hole. 3. Use rubber o-rings on the wooden dowel to help control the fluff of the composition when ramming.

If you drill a lengthwise hole in the ramming dowel, then put a small dowel in the center of the motor housing you can ram the fuel in and remove the small dowel to make a core burner engine, fill the core left by the small dowel with black powder. That way the whole core surface area burns at the same time. Much more power. Also water putty makes great rocket nozzles, and you can mold a power enhancing nozzle into it also.

hey, when I was in my late teens, I was trying to get my niece into science with rockets. But even though the "rocket starter switch" cord provided was long, and we launched it INSIDE my car, with the door open, I gust if wind blew it over just as it was launched and it came right at us!!! So I then learned how to make wireless firing systems to get more distance when launching. I've been able to make: -infrared firing system ( about 50ft ) -radio wave ( about 300ft ) -cell phone ( limitless, I guess... ) If you ever want to make a video on how to make wireless firing systems. I made 3 schematics, 1 for each type, and provided them to my local hobbyshop. And will gladly provide them to you. Ironically, the cheapest to make is the cellphone version...

What I like about this project is that it is not only very affordable, but easily scalable: You can use longer and/or wider PVC tubing with more propellent in it and/or add multiple tubes to your rocket to get even higher altitudes! I wonder how big of a tube you can use before the laws of physics make it impractical? (i.e. Can an 8 inch diameter PVC pipe contain the resulting internal pressure and would its added weight not be worth the effort?) Very nice! JW3HH

Do you know if there is a way to get a slower, more efficient burn? I wanna make sure my rockets go as high as possible for as long as possible, and a burn of about 3 seconds doesn't sound good enough for maximum efficiency. Even if it's just a second or 2 longer, it'll probably make a major difference. I'd make the engine longer and increase the quantities for the white poder, but unfortunately I don't exactly know much about pyrotechnics and how it'll react.

Only the top and the parachute get launched and the rocket stays put on the launch pad. Any pointers? By the way, please keep them coming!!

I love watching this but would never make any of it

[@ryanjorgensen3297]

Yesssss same

[@elainemaxfield2978]

me too

[@SpookyJackie]

Same here, all his videos are fun to watch but I wouldn't do any of it.

[@YourMJK]

I would totally do it but getting potassium nitrate in Germany isn't as easy as it is in the US. And importing "stump remover" from the UK or the US from Amazon isn't really cheap and would certainly cause problems at shipping

[@bramf4172]

YES YOU CAN! NOTHING IS IMPOSSIBLE! DON'T LET YOUR DREAMS BE DREAMS! JUST DO IT!

[@djemkurtgagatam6710]

where do you get an oak dowel what can i use aside from it? btw thanks @wacka appreciate much

[@elmohaikio2687]

Honestly these old style videos were so much better than the new ones

[@Mr215Alive]

"Highly flammable" *places in oven

[@nimamashitongxinglian1213]

The same when he wacks it with the stick and hammer

[@unknowngamer2833]

bruh potassium nitrate itself is a salt and non flammable

[@nimamashitongxinglian1213]

That is what I realized after testing it

[@ville3609]

Please can you make more rocket videos? I think they are the best videos and I want to see something bigger or just more different when the normal Randomizer rocket! I really hope you read this and maby you can do it....? Keep doing the best videos on KZbin! Bye

[@brianb9969]

made one, works great!

[@jrscsuddhaschaudhuri8174]

Hey Thompson, I thank you very much, for this awesome idea. But a question is there... how u are making this rocket ignited? i mean you are using the launch pad but i dont have any like yous. So what's basically is taking place at the pad? is it ignited by fire? or anything else like electric spark?

[@jacobusvisser6428]

Mr. Thompson. Would you kindly share an estimate on the force outputted by your rocket, in Newtons. Thank-you.

[@BKKJunE]

Yeah, everybody knows that... But we don't know the velocity... -.-

[@mariodelgado7975]

do u have to use stump remover

[@mariodelgado7975]

i cant convince my parents to buy stump remover

[@xINVISIGOTHx]

Thats so stinkin cool man!!!

[@rogerwhitley6107]

What do you do to keep the pvc from lighting and or melting? In my experience a heat shield casing of cement or plaster is the only way to keep the fuel from lighting the pvc; ie why the world uses wax coated craft paper, fire retardant pressed cardboard or aluminium tubing.
