Cool photos of shockwaves, explosions etc.

Came across a great American Scientist reprint, "High-speed Imaging of Shock Waves, Explosions and Gunshots". Sounds like fun

Wow! Interesting stuff. Thanks for sharing.
Wonder how long before someone edits one of the pics to show a spud?

cool
I like the banana picture

[kablooie]

Yeah, the banana thing is very cool. Also the revolver picture. It hadn't occurred to me that there is not a complete seal against the barrel, I guess that is kind of obvious though. Here's a cool video for those of you who like to see fruit destroyed:

Could someone post the picture acrobat reader won't work for me it says there is bad cmap encoding text or somthing like that.

These are most of the images if you can't view the PDF, i'm too lazy to add the captions.

Cool stuff.
I saw something on instructables for constructing a high speed camera similar to some of these using a camera flash in a dark room.

You can really see the way the projectile goes straight and the gasses/ shock wave tend to cone or balloon outwards.
Which is also a principal to keep in mind for sound suppressor design as well. 8)

That looks cool. Ever seen images of the WWII era "swimming pool makers" (5" guns) going off? I'll see if I can find some. There are also some good images of shockwave condensation effect from the Vietnam era.

EDIT: Not exactly from Vietnam but same effect.

And here's those swimming pool makers I told you about...

Cool photos. The explosion ones remind me of a talk I went to at my school from Sandia National Labs. They had a video that they made to test a 1,000,000 frames per second camera. It was a small high explosive charge in a cubical plastic container filled with water. It was cool because you could see the shock wave go out and bounce off the wall of the plastic.

Edit: The article is really cool too.
Here is an html version for those who don't like PDFs
