LAW Rocket Launcher Replica w/Flash Cotton Muzzle Blast [HD Video Tutorial]

This rocket launcher uses flash cotton (gun cotton, nitrocellulose) to simulate the muzzle blast of a real rocket. It is an excellent prop for home movies, or just a great addition to a Halloween costume. Needless to say, it should not be fired indoors or at other living creatures. Flash cotton does not usually cause burns to the skin, but that does not mean it never will. It does produce a real flame so it also should not be used in dry or flammable environments.

Flash cotton can be purchased many places online, or at local magic shops for quite reasonable prices.

The total price of this project was about $35.

what studies did you do? im in electronics and im loving these projects

[Nighthawkinlight]

@achrimsfreak Thanks for your comment, I was in community college for general studies for a short period before I discontinued that and started a landscaping company. As of yet I have not gone into any other higher education.

[RocketBurn11]

Do you make your own cotton? Seems like something you would do, lol.

A little hazardous for my taste.

[Nighthawkinlight]

@RocketBurn11 Yeah I sure do.

[pyr0ph1L]

Really cool! :) .. Although I am looking forward to some more fireworks :D

[Nighthawkinlight]

@pyr0ph1L I know, me too. I've been working on licensing issues for the better part of a year. I'm close to done with that but then there are some other issues I need to work out before I can start building regularly again. It could take as long as late next summer, but we'll see.

[jonijoni01]

 how long is this in centimetres? please

[Ahhmymanwich]

To make this actually fire a rocket, get a rocket and tie the fuse to the igniter. Pull the trigger and there u have it

[1point61803]

@Nighthawkinlight Oh wow, what's the company name?

[Nanbopally]

@Nighthawkinlight ME too! why pay out the ass for reading books when we can un around in the forest blowing shit up!

[demnlordd666]

[redneckengland]

[gamogunguy]

i think that this and make magazine are the best channels on yotube

[SnakeEyes732]

Isnt fire suposed to come out of the back

[TomashPL58]

I've taken few tries of building real R-L with success. Can't upload video tough. Illegal in my country. Sometimes i envy You, americans for freedom that govt. gives to You. Still knowledge is really something here ;)

[SiberianSilverfall]

@Nighthawkinlight I had an idea with this design, instead of flash cotton, why not make a smaller internal barrel to fit model rocket engines. Then make minor changes so the igniter will launch the rocket engines. Sound like a good plan?
