200 gallon HHO detonation

Approximately 0.75 cubic meters or 27 cubic feet of HHO in 4 large trash bags.

This took place at midnight on the 4th of july, and it was heard at least 5 miles away.
Two car batteries with holes drilled into the vent caps and polypropylene tubes hot glued to them made up the electrolysis apparatus, each submerged in a 5 gallon bucket of water for cooling.
The power supply was an oil cooled 1.5 Kw transformer, delivering approximately 100 amps at 18VDC average to the batteries. I think it took 6 hours or so to fill up, not including time to find the leaks and re-fill the last 20%
I may or may not have something planned for new years 2012, i'm talking about perhaps a 9 foot cube made from aluminium foil, (hydrogen goes though polyethylene like gasoline through a Styrofoam cup) at about 1000 feet altitude.

While something like this is not safe to stand next to, it wouldn't kill you even if you did. Might put you in the hospital with lung damage though if you're closer than a few feet or about 2 meters.
What I do know is the smaller explosions, such as filling a tire full of hho are much more interesting.
Filling a 2 liter soda can with hho at 140 psi and using distributed spark gaps to detonate it on both ends of the bottle at the same time yields impressive results.

its funny normally you see light first then hear the sound lol

@summt5697 who cares about the legality of it?

I've watched videos on youtube of people hacking websites, who the fuck cares if someone decides to make their own small scale explosives in their own backyard.

@timpovsqb psst he said 0.75 not 75 and yeah show the being filled would be total proof

[Me102288]

ok, 1 cubic meter = 264 gallons.. by my calculation that explosion would have deafen'ed everybody within 1000 feet (approx.) and would have been heard like 10 miles away. Ya, I agree with timpovsqb, I think he really meant .75 gallons not cubic meters.

looks like it was quite big.. just sad you dont see alot and the sound is fucked :/

that looked big.
