Bottle Launcher "Mad Hilda XXL

[Bazooka]

This is my advanced Bottle Bazooka.
I had an account here, but lost my email.
So maybe you will remember some of the used parts.

I wanted to get my Bazooka loaded clean and fast.
I wanted to get the perfect fuelmix "out of the box", so I use premium lighters with high output and some one-way valves to make sure, the mix can flow without any resistance and provides enough pressure for closing the required valves and fire my bottle.

This is the German version !
I have some attachments for Nerf Darts, Pingpong balls , marbles...
But in Germany, the laws say: if a projectile flies through a barrel, it's a forbidden weapon. But if it flies over a barrel (like a crossbow) it's ok.

So, this is the bottle launcher version, where a projectile is shot over a barrel.
If it hits in about 3-5m it's like a Thyson fist. Fast loud an brutal.

The third one one the left is a Pingpong all cannon with a Magazine for 8 Pingpongball's. It works like a Pumpaction shotgun.
The Pingpongball's "detonate" at the wall at ranges to about 4m.
The principle is easy: ten times more power as needed to fire the ball. And a little invention I use in all of my Cannons. The Boga principle^^

The other is the Nerv sniper attachment, but I have to use special darts for it. The normal ones can't hold the pressure of the Boga Momentum and simply detonate at the end of the barrel with a loud bang. Mine are epoxy armed so they fly through wooden plates, if I use a nail as tip.

The Boga principle.
You know this water fountains, that shot clear water ? In a wide range looking like a solid "piece of water" ?
They use the same tech.
They "order" the stream in a line, straight, without interference.
The water is traveling faster and concentrated through the air.

With combustion gases you can do the same. So, they get faster. If you do it to the extreme (Google tin can cannon or Boga,Puga, Lantanka), it breaks Soundbarrier.
But you have to build projectiles, that can stand the momentum. Normal Nerf Darts or bottles, which are made of too thin PET, wil break with a loud bang at the end of the barrel.

Very interesting work!

I love the "spade grip", reminds me of a friend's post-apocalyptic (airsoft!) RPK:

[Bazooka]

Lol. It started all with the ban of fireworks 2020.
I wanted to make loud boooms without firework, so I looked around the world, how to make a loooud bang without smoke.
I came to "Boga" a forbidden, but we'll known toy in phillipines. It uses this principle to make very fast gasses breaking some kind of Soundbarrier when hitting the outside air. The more chambers, the faster...till the borders of the can. More then 10 in line and the whole thing will explode.

I knew this, and I find it very interesting. I once tried a small "double combustion chamber" pistol that actually shot with more energy. It was a combustion weapon (not hybrid). I imagine that the space between the two cans is the second chamber and the PET bottle is the first. It obviously has more power than if it were a normal single-chamber combustion cannon. Good technique to enhance this type of launchers.

This yasu user gets the noise with the detonation. Check out his channel on youtube because it is interesting to see his concepts and techniques for simple, semi-automatic and fully automatic noise cannons. Maybe it will come in handy for your future noise cannons or launchers.

That's it. It describes the effect perfectly. I use it like this:
