Hydrogen-oxygen detonations in soap bubbles, video added

[Linden.g]

Over the last year I've been exploring Schlieren optics. I built a Z-system out of two Newtonian reflecting telescope mirrors. https://www.facebook.com/photo.php?fbid=705986539741502&set=pb.100009904868801.-2207520000.1561592016.&type=3&theater The ability to visualize sound compression waves and gas density is fascinating. The first image shows the flame front from a 2:1 ratio of hydrogen and oxygen detonated inside a 1 inch soap bubble from the left hand side using a Tesla arc. You can see that the soap film has ripped half way across the bubble. The second images is almost at the same point but was donated from the back. The soap film is ripping towards the camera. The motion was stopped using a 500 ns high speed air gap flash. The monochromatic colour is due to a narrow band pass filter to suppress the light from the explosion.

impressive!!!

Thanks,

A few more closer in showing ripping through the bi-layer and then residue collecting on the opposite side of the detonation point.

Very cool, so this your setup then?

Great work, Linden. Thank you for sharing. My head is exploding from imagining the complexity and danger of this imaging venture of yours

How did you precisely control of amount of hydrogen and oxygen mix, inside a soap bubble? I did not know you can buy those gases as a private individual. Solid rocket power may be easier to buy from Hobby Lobby.

Interesting stuff indeed!!

I suspect the H2 and O2 can be created with simple electrolysis, or just H2 with pool acid (dilute HCL often called Muratic) and Zinc.

Might be electrolysis in soapy water to create the bubble mixtures of H2 and O2.

Very cool setup and images!!

Best,

Here is what it looks like in high speed video https://www.facebook.com/100009904868801/videos/832499530423535/?id=100009904868801

... wow, very nice. Thanks for the links.
