Hard to get right?
Do you mean the right amount of spray?

A woman i do gardening for has a can of this in her shed for a small flamethrower thing that is meant to burn small path weeds.

Its mix is
30% propane
70% butane


Will this be any good to use as fuel?

The bottles are overlapped by about 1" and it feels very secure.

Here is my new ghetto gun which i made yesterday, the materials are a sprite bottle, a fanta bottle and some pvc tube which fits very tightly into the bottle top.
Here are some pics:

Yeah, this stuff is really damn strong, if its laid down i can stand on it (60kg) and it doesnt break or even bend, lol

They don't explode into millions of peices because after bonfire night or whenever everyone has fireworks you can walk down the road and find all the empty cardboard tubes with the wooden sticks on them

how to attatch the barrel to the chamber:

get a roll of duct tape. start wrapping one end of the barrel peice in tape untill the bottom is wide enough to fit tightly inside the chamber peice. apply superglue and enjoy......


Wow that is a bloody amazing idea!
Thanks!
Got that bit solved now ...

Oh yeah thats very true

I'm still not sure how to go about attaching the barrel and combustion chamber together

You'd need something to bulk out the size of the barrel to fit in the chamber...

..Use remote ignition and don't let it get wet (no potatos) :wink:

Could you explain the bulking out the barrel in a bit more detail with a diagram if you can be bothered :D

Nah, can't be bothered with remote ...

I have about 1ft of 4mm thick 85mm cardboard tubing and about 2 and 1/2 ft of 1mm thick 50mm tubing.

Do you rekon i would be able to make a combustion cannon out of this or do you rekon its to weak, to be honest i don't give a damn if it breaks because its not like i'm going to get carboard ...

LMAO!

Are you been serious?

As for me, im not doing anything for 4th July apart from going to school, bloody England

Broke the sparker

It got clogged with blue tac that i was using to hold it on and i tried to take it apart to unclog it and it broke.

Gonna have to buy a new one when i go downtown 2moro lunch.

I had a go with it again today but for the first 30mins i couldn't get it to work and gave up and went back inside, when i put the spray down i discovered the problem... it was bloody anti-perspirant

Grabbed some proper deodrant and have spent the last hour doing target practice.

Nice, much better than my first attempt!

I think it didn't work the first time because i put too much lynx in it, but now i know for future reference
