Anomaly before implosion and also explosion of HHO

[HARLIN]

Hi all,

December 31-2012 we ignited 60ltr of pure HHO just for fun, a big implosion, the pictures are amazing.
I had a little black out and my brother had a pain on his chest for days, so don't try this at home, lol.
We also ignited 60ltr HHO with 0.5ltr watermist, result was an explosion.
When looking at the pictures we saw a purple anomaly appearing a fraction before ignition  it even reflects me
taking the picture  , anyone any idea, i have no idea what this is
Here's the vid.:

If you have a subwoofer engaged, turn it down, it's gonna be loud 

Nice day to you all

Nice experiment. It really drives home the danger of working with electrolysis gas products, whatever you choose to call them.

The purple flash is an artifact of digital video cameras. Even though it appears that it happens before the bag explosion, as in your still shot showing the purple and the intact bag, it actually happens at the moment of the flash. I have lots of these anomalous flashes appearing below or above the actual location of the flash, in some of my videos of sparking electrostatic machines. This same camera phenomenon causes Jose Escamilla's "rods" and also makes airplane propellers look curved or split, in videos taken from the cockpit through the propeller disc. Unlike film cameras, the digital video camera scans, line by line. So the bottom of the frame is always slightly later in time than the top of the frame. By the time the camera has scanned past the intact bag, the explosion happens and so you see the purple flare at the bottom of the frame.

The double sound is probably due to the reflection off the walls/fences. You are set up in a perfect "echo chamber" being between two straight walls.

I'm not sure why you get implosion in one case and explosion in the next. It may have to do with the water vapor. If you have a water mist in there, when it flashes to steam it will expand 1600 times volume. If the gas is dry, just hydrogen and oxygen, you get a pure implosion, but if it's wet you get the expansion due to the tiny droplets of liquid water flashing to steam. Maybe.

Thank you,

We were hiding in a shed for safety.
The time difference in building the frame, i didn't know, thx
A clear explanation, but
There are buts :
1 The purple anomaly reflects me, crouched filming in the doorway of the shed, how is that possible?
2 The cirkel you see around the anomaly is also moving toward the bag (see frame 2 attached) from point of ignition inside the shed
3 Sound of implosion has 3 peaks and you do not hear a simular sound by the explosion, no echo, a complete different sound
I believe there's more to it, when you look at the flash of the implosion, it looks electrical.
There will be a next experiment with a hs-cam, hopefully.

If you ignite pure HHO you always get an implosion, take a vacuum (little)sandwichbag; fill it with HHO (high quality cell needed, no 'steamer')
and put it under water and ignite, then you see an implosion.
When you have just a little air in the bag before filling; you will have an explosion when ignited, with watermist the
expansion is maximized by at least factor 1600 dep. on temp.

My guess is that, in filling that large black bag, an amount of air got in. This means that your H2 and O2 mixture was not exactly stochiometric.

Had the mixture been perfectly stochiometric, the flame front would have travelled at in excess of the speed of sound, and the resulting boom would have burst your ear drums, and those within a considerable distance of the event.

What you are doing is profoundly dangerous.

[HARLIN]

It's possible, some (very little amount) air got inside.
We had earplugs in 

I did it and yes it was not without risk, next time there will
be more preperation on behalve of safety.
There will be a Faraday-cage, because of the discharge, which
was the most dangerous
