Nuclear purple flash, a bang that'll echo for 10 seconds (at least in

I was thinking, buy 3-4 helium balloons, tie one balloon full of O/A
to them, add a fuse, light the fuse and let it fly up in the air
before exploding. Kids might like it.

Turn it into a science project, fill your ballons with hydrogen/oxygen by

i graduated college in '82. we messed around w/ oxy-acetylene things there
in the metal shop. i posted this once before, i foolishly volunteered to
light the "fuse" and it blew up the instant i touched the match to it, right
next to me. i completely lost my hearing for a few minutes. was scary.
after college us guys rented a "loft" in brooklyn. was the top floor, the
wrought iron roof trusses were in our space. i have a faint recollection
someone lit a oxy-acetylene thing indoors. was so loud and there was such a
shock wave dust gently fell from every truss in the place. i think that's
what made us all wide eyed, not so much the blast but that it shook loose
dust from all the trusses. we were like "*whoa*".

i don't think i/we ever had the balls to even consider doing a 50 gallon
bag. especially after witnessing what (a MUCH smaller) two-taped-together
styrofoam soup bowls sounds like.

I've lit mixtures of H2 and O2 from electrolysis, and the reaction did
not seem nearly as energetic as acetylene and oxygen.

Don't. If you want to fuss around with
acetylene, get some calcium carbide and
play with it.

We used to fill taped up dry cleaning bags with methane for list, and
then hang and oxy-acetylene bag under it. For fusing, we used cannon
fuse & "detheramlizer" fuse. Thsi was like havy cotton cord, that would
char at about 1/4" a minute. It was used to retrieve model gliders bu
releasing the horizontal tail stabilizer after a period of time.

They would get very high up befoe there was a good flash & boom form the
O-A, followed by an orange firebal from the methane. No blown out
windows, and we all still have (most) of our hearing.

Do not try this at home, etc.

by electrolysis of water instead of using O/A.

It goes bang, but the energy released isn't nearly on a parr with O-A.
We did some careful comparisons when I was a kid, and O-A wins hands
down.

Acetylene has a free gas molecular weight of about 26. Hydrogen, 2.
Oxygen, 32.

67.2L of gas at 2(H2)+1(O2) ratio weighs 34 grams (3 mole volume)
67.2L of gas at 2(C2H2)+10(O2) ratio weighs 93 grams (3 mole volume)


Sooo... The trash bag full of acetylene/O2 has almost 3 times the mass of
the H2/O2 mixture.

Consider what the relative explosive force of three sticks of dynamite
would be vs. one.

It's not the mass of the gas doing the damage but the energy of the reaction
and the speed with which the reaction occurs.

In particular, there is a triple bond in acetylene that stores a LOT of
energy. When that let's go, you get a lot more bang for your buck than
just connecting a couple hydrogen atoms to an oxygen.

That's all fine and good, but it's the amount of mass set moving that
conveys an explosion's force to the objects around.

If the acetylene reaction were 1000 times as strong as the H/O reaction,
and you had 1/10th the mass in Acetylene mix that you had of Hydrogen
mix, you'd get the same net explosive force.

Explosion force is not linear with mass.

Simply fill a 3 liter soda bottle about 2/3 full of water, pour in a few
ounces of Drano, add a couple bits of aluminum, foil is best but
cuttings work, and shake well. Then attach a good sized balloon to the
top of the bottle to be filled by the hydrogen Generator you just
manufactured.

When filled, take outside, tie closed with Cotton string....long
one...light end of cotton string and release.

Up and away!

I guess because I played around with it a lot
when I was a kid. I grew up in coal mining
country and it was easy to get. I never managed
to hurt myself worse than ringing ears and a
cuff from my dad. There's considerably more
potential for destruction with an O/A rig.
