Well, has anyone lit an oxy acc balloon today?

[MAC702]

Balloons? Why didn't I think of that? The neighbors kept calling the cops when I was a kid because my dad would light 5-gal water bottles in the middle of the street.

a wile back some one posted a new papper artical abut a guy who was taking some of them to the ball game and blew up his car on the way.
i like to shoot paint cans with a 12 gage with a canle behind them.
i will have to dig you up a pic its great fun. probly best not to do this in the city, one more bonus to contry living.

It's drier than a popcorn fart here, the temperature is 93°, the humidity is 14%, and I'm surrounded by tall, dry grass.

I'll be down at the neighbor's pond for the 7/4 tube steak BBQ and safe-'n-sane fireworks display!

Have a safe, happy 4th, brethren!

No, But yesterday my neighbor lit a bondfire with gasoline and got a helicopter ride to the burn center. He came home today all wrapped up ...Bob

When i was in high school shop class, the teacher lit a balloon filed with oxygen, it just popped. Then he light one filled with acc, it just popped with a flameup. Then he filled a smaller one with oxy and acc, it went KABOOOM hehehe. Dust fell from the shop ceiling.

Not a bad year so far. Only two houses on fire that I can see from my yard...

How about Acetylene bombs?

Acetylene will explode under compression at 14.5 psi (100 kPa). I haven't done this, but heard that if you put acetylene in a balloon, tie it shut, fasten a weight, and drop it in water; it will explode. It will have to sink to a depth of about 33.5 feet before the hydrostatic pressure reaches this level.

Anybody do this before?

[Tailshaft56]

I don't think it positively will explode. It's true it becomes unstable at pressures above 15 psi ( the reason it comes dissolved in acetone ). The bottle pressure of a full acet. tank is 250 psi. Granted the Acet. is dissolved there must still be some gas at the top of the tank.

Dry ice/soda bottles are just as loud and a whole bunch cheaper and safer.

Fill about 1/3 full of room temp water, add 4 pieces of dry ice (pellets), and close the cap, then throw. BOOM!

What's that old saying?........

Oh ya...."A fool and his fingers are soon parted" ..................or was that money?

[Fishy Jim]

Dry ice actually takes a little while to work up to "boom" pressure. The reason it pops at all is because the cold prevents the plastic from expanding until the threshold is reached and it blows apart like a balloon.

I'm not sure what force the shrapnel actually has, but it's rather light, so I imagine it to be minimal. You could poke an eye out if you weren't careful. Maybe even get scratched up.

Just remember that it's not fun and games unless someone loses an eyeball, or I think that's how it goes...
