Fireworks Playground
A place where any kid with a legal guardian can play with on-site purchased pre-approved 'Safe and Sane' fireworks. | |
In locations in which fireworks are otherwise outlawed, kids, wearing safety glasses and maybe fire gloves, accompanied by a parent and assisted and monitored by staff, can watch, light, and play with 'safe' fireworks, year-round, in this outdoor or maybe ventilated indoor rink-style environment.
"Safe and Sane" classification.

So am I. Fireworks are meant to be dangerous, and I
am saddened by the fact that bangers (firecrackers)
and helicopters (wonderful things that would spin off
in random and potentially harmful directions) have
been banned in the UK. |
|
| |
This is a disgusting travesty of pyrotechnics perpetrated by the
Safety Fascists (Kill 'em all !). |
|
| |
No, no, a thousand bangs no. |
|
| |
Oh, and what [MB] said … if it can't blow your hand off above the
wrist, it ain't worth having. |
|
| |
Only "Unsafe and Insane" (tm) brand fireworks for me. |
|
| |
I still have ten fingers despite putting a lit m-80 in a plastic
milk jug (so far so good) but then going back and swatting it
into the air after my first swat missed. Blew up in mid air
about five feet from my hand. On the pretty long list of
stupid things I did as a kid. |
|
| |
Anyway, safety and sanity has no place in pyrotechnic fun
and games. |
|
| |
We used to make flame throwers as teenagers by packing a certain brand of weedkiller and sugar mix together and placing it in a pipe with one end flattened over, and the other end lit with a match. I have no idea now why none ever simply exploded, but the (short lived) roaring flame that emerged was simply terrifying and hellish. |

You should have tried stealing an 11kg propane cylinder, taking it out into a secluded field, then carefully building a fire round it, includind lifting it on bricks and packing coal under and around it for maximum heating effect. |
|
| |
When the safety disc blew, it started to emit a five metre jet of flame accompanied by an unearthly screeching noise, at which point the comment "D'you think that's all we'll get ?" elicited the inevitable response from Fate of a spectacular BLEVE. |
|
| |
After the shards of red-hot shrapnel finished whirring overhead, the same individual who had asked the first question the enquired as to "whether anyone might have noticed that". |
|
| |
As I've been comtemplating a not unsimilar
experiment, I am curious as to why the cylinder goes
bang some time after the safety disc bursts. The
venting tank ought to contain only propane, sans
oxygen. |
|
| |
The pressure in the tank rises due to the input of heat, until the safety disc ruptures, but if the rate of heat input is high enough, and the aperture is venting gas, not liquid, then the pressure continues to rise until the container itself fails catastrophically. |
|
| |
The critical temperature for propane is only 97C, easy enough to attain. Just make sure you steal enough coal. |
|
| |
We recommend observing this phenomenon from a trench dug at least 1.5 metres deep; do not place you faith in hiding behind anything smaller than a mature deciduous hardwood tree. Protective headgear is also essential; at the time of the original experiment, inverted aluminium pressure cookers were de rigeur, having been found to combine the desirable properties of internal diameter, relatively light weight, and considerable resistance to high-velocity impacts. |
|
| |
I'm voting for this. I would love to do it. (I being the kid, that
is.) |
|
| |
// if it can't blow your hand off above the wrist, it ain't worth

|
| |
I'm guessing that all y'all who talk lightly about loosing a
hand are typing with two largely complete hands. Worth
considering. |
|
| |
Just think of it as a form of evolutionary selection pressure. |
|
| |
For example, there are no careless, slapdash or incompetent explosives engineers. Well, there are, but only briefly.Only those f a thoughtful, cautious and meticulous disposition survive in the profession. |
|
| |
It's a somewhat unforgiving technology. |
