well in my first combustion (made from a glue stick and some ally tube back when i was 15 or so..) my first attempt was a successful dryfire. my second attempt trying to fire a pin resulted in the lid of the glue stick flying off and hitting me on the face... how embarrassing... :lol:

there has also been a time when i was waiting for some glue to dry, decided i was going to play some computer, and gluing my self to the mouse...

what about you guys??

Needed to look down range first. I didn't think much of the van parked 20 feet away. What could a marshmallow possibly do?

I expected more, JSR :D

1) My first pneumatic cannon, consisted of a single fire extinguisher as a chamber, flew off at 100PSI when I used some plastic shallow-threaded fitting from the fire extinguisher valve.

2) With my hybrid cannon, I shot a .303 projectile through 4" or so of solid pine and through my big garage door. I had done previous tests where the .303 only penetrated an inch in to the pine, turns out this time I had made a decent sabot. At least the car wasn't on the other side of the garage door, usually it is.

Of course there are more :D for example the first time I fired this thing, I didn't expect the piston to move back with much force so there wasn't a piston buffer, I was aiming down the barrel and about to fire when the phone rang, so I lowered the muzzle to the ground and shot it. The piston flew back into my chest with enough force to break the skin and leave a substantial bruise. Were it not for that call, it would have gone straight into my eye :roll:

Oh back in the days of my first piston cannon, I didn't expect the cannon to be so powerful. I had a huge roll of carpet at one end of my garden which I aimed at with my golfball gun, I missed. It hit the fence and flew on to the neighbours roof.

'Nother time but with the VAL, I was shooting a 32" or so CRT TV with a golfball at about 40PSI (thinking it was enough), the golfball rebounded and flew over my head for a good hundred meters but the TV screen had imploded.

I had a pneumatic that after months of successful fireing, the entire 4 inch reducer onthe back blew out... Along with some fittings, a guage, and a ball valve... It blew the cannon out of my hands and the reducer 120' away, almost hitting my neighbors house...

I also shot water once... And didn't remember newtons first law...

Not something to joke about really.
There was an incident where one individual was killed when a back-firing clean-out cap hit them in the chest, triggering Commotio Cordis. He died as a result.

It's one thing to discuss this kind of thing from a sensible perspective, but the idea of discussing such potentially dangerous events with LOL smilies and "OMG too funny" posts really doesn't sit well with me at all.

Newton's 1st law: "Corpus omne perseverare in statu suo quiescendi vel movendi uniformiter in directum, nisi quatenus a viribus impressis cogitur statum illum mutare."

Or a rough translation: "A object's velocity and direction of travel will remain constant unless acted upon by a unbalanced force".

Is that what you mean, or did you mean to reference Newton's 3rd law?

I had a ricochet almost penetrate my wall, shot a tile to pieces on the floor when piston valve failed, almost got hit in the head by a golf ball ricochet and forgot to close a ball valve before filling a pneumatic with air.

I agree with Ragnarok.
