Some years back I was at a party and a guy loaded up a bunch of tubes with doubles.  It seemed to work and no one died or got injured.



I did not pay attention to how he staged the fuses, etc.  I did ask him about it and he just smiled and said "don't try that at home"



It feels to me like a pretty stupid idea.  



Just how stupid is it?  Is there some sane and safe way to actually do this?

Just make sure the top one fires first.

Yeah.  That's the trick though.  I don't feel like most fuses available to the consumer have a steady/reliable burn rate.  It seems like if you try to time it using SWAG methods, you risk the second one blowing near or at the ground.

No beers.  I pull straight from a bottle of whiskey while I light.

I've tried it before. Just twisted both fuses together and lite them at the same time. It worked fine.

Did you worry about the timing?  How do you know that one won't blow up on the ground before the other one launches?  



It seems like you would want them both in the air when they went.  If you just pigtail the fuses, what prevents this?

I used to tie 2 together and they both went when lit. Depends on the size mortar though. Never have chanced it with the larger ones.

Are you sure the doubles he was firing weren't designed that way?

I've fired doubles before, but they were built that way.

What's worse is when the top one goes off and knocks the tube over and the second goes flying right at you.

No, these were discrete shells which he twisted / tied the fuses together.

Tubes are screwed into plywood.  They aren't tipping over.

I don't want to dig at a scab, but since you brought it up, what happened?  



Even though I'm a drunk maniac I'm actually super careful about this stuff.  Worst thing I ever did was accidentally load one upside down.  My uncle was standing next to me and yelled out as I was lighting it "You idiot!  Run!"  We all ran.  Mortor bursted, everyone was fine and we all agreed I was no longer permitted to light for the rest of the evening.

I've done it before when I was a teenager.  As said above just twist the fuses together.  Nothing crazy happened.  The trick is to light both fuses or just the top one, which will ignite the second one, maybe.  :)   Of course this is not advice or a recommendation.

Thinking back I remember planning on getting the proper sized tube, cardboard or pvc.  Loading 10 or 20 in it and lighting the top one...  Basically a god sized Roman candle.  It's probably a good thing I never tried it.

Takes time to screw tube into plywood, won't take time to screw 2 tubes into same plywood and light . Light both in the same tube and dooooo it

It's called "piggybacking".    You put the first shell down with its fuse wrapped on the top of it.   You slide the second shell down and light it as normal or fuse it in if using in a built rack.   Many on PyroUniverse will skypuke using that technique.   It is advised, however, that you do not have a canister shell as your top shell, however you can have one on the bottom.


BTW... NEVER use PVC for launching mortars.    If the shell malfunctions, you will have a shrapnel bomb going off.

Thanks and everyone should know this.  The only thing I use PVC for is flushing my shit.  In my last house, I had a neighbor who had built a multi-level workshop and had plumbed in compressed air from his basement to his garage using PVC.





I refused to step foot into the place.  He thought I was I huge dick because of it.  I tried to explain it to him but he wouldn't listen.  





Sorry but I'm not going to be standing in your garage when you drop a rake and things go boom.

Not two, but I've put one in upside down and blown the tube up by accident.

If you are near a shallow body of water it's also fun to throw them in and watch the underwater explosions.

We used to tie medium sized skyrockets, together all the time. Tip, make sure that the larger one ignites first. We had a few go up into the air about head height, then roll 90 degrees, then big one ignites sending both rockets horizontally at down the street about 6 feet off the ground. Boom!

I wouldn't suggest it.  An accident with a single load mortar cost me the right half of my moustache and some damage to my lip around a decade ago, and last year a friend of the missus lost an eye and had to have reconstructive surgery to her face after a double load went wrong.
