Mini Cannon Answered

This video by YouTube user 43287633 shows off the abilities of a tiny custom cannon. Check it out to see this thing take on soda cans, glasses, balloons, and more. Unfortunately, there's no other information about this one, but I do love the fact that the firing range is the creator's own desk. That's some serious confidence in the reliability of the cannon.

I can see how to make one of them pretty easily but I don't know what the score is with gunpowder here...

Just don't buy metal tubing and gunpowder on the same credit card.

Living round your way, that would get you a knock on the door from a man driving a cage-wrapped landrover...

True, you can buy me the gunpowder and mail it, with a big label beside the contents saying, totally not a terrorist, that's bound to work...

Eh I really am unsure on that, don't even know about model rocket engines, which has come up in a project before, still on the blocks that one...

For model rockets, try zinc and sulphur - as far as I know both can be purchased freely across the UK (from chemical suppliers), but together they make a useful (if smoky) rocket fuel.

The first place I heard about it (Rocket Boys) called it zincoshine, because they used pure alcohol as a binder.

You two smart-alecs forget that Killerjackalope is in Northern Ireland.

On top of the OTT UK restrictions on materials that could potentially become weapons, his little corner of the Kingdom has had decades of violence in which home-made bombs played a major part.

It's the only part of the UK where police are routinely armed on street patrols.

:-D  Well, what I discovered was that Beijing local food was pretty similar to your average San Francisco Chinese, but quite different from Vancouver or L.A. Chinese (both of which have strong Hong Kong influences). 

As for "Chinese" between the Rockies and the Shenandoah Valley, all I can say is that it's about as authentic as a Charlie Chan movie ;-/  I think that means, "they taste funny."

Zincoshine's a rocket propellant, though.  I don't know if it expands quickly enough to drive a cannon ball.

Select as Best AnswerUndo Best Answer

user
killerjackalope (author)Kiteman2010-05-12

Hmm, it's possible, could do a rather long version of the cannon to make it effective with slower expanding propellants...

Alternatively I could try a fuel air one to start with, I probably have the parts for that in my junk drawer...

If you are patient enough, you could wait for New Year's Eve and buy some firecrackers. They are quite cheap and you would get black powder and fuses at the same time. Where I live (Germany) you get 6 huge or many (I think more than 40) big, medium and small sized firecrackers mixed as one pack for 2€ (1.7£ / 2.6$).

These are the crackers ( I found the pictures somewhere on the Internet ):
huge
mix pack

Maybe you get similar crackers where you live. I think black powder would be one of the best propellants.

No there not illegal in Canada. They don't sell them many places anymore, not on the coast anyway, but I got a whack of them in Winlaw recently, including some 2" mortars and DOT Class C multi packs, bottle rockets and such. They did put more restrictions on KNO3 a year ago, but fortunatly I still have 5 kilos =).

 I believe that is pubspeak for "what's the deal with that little bit o' gunpowder" or "dang, it's really gunpowder used in there".  You have to have tiny balls to use that thing.

 I saw a blackpowder derringer that shoots BB's that uses just the ignitor / percussion cap for propellant. It would be more complex with the firing pin and all, but still pretty sweet.

circuitbreaker (author)2010-11-25

No. I just like making rockets and I make my own fuel for them, and when you launch rockets regularly, it uses it fairly fast. I admit that it is way more than I need, but it was a way better deal to get that much and it will last me years. I am very careful when dealing with it and use full protective gear when making the fuel.

if you use matches you might end up droping it and start a fire very quick,but with a cigerate you can get it off the floor in time.(don't smoke it can give you lung cancer and kill you.)
