Faux "Hi Speed" Photography

I was asked to speak to a group of cub scouts tomorrow about the science of photography. I though it would be fun to show them how science uses photography. So I through together a "time lapse" deal, showing what happens when a balloon explodes.

We filled a balloon with baby powder, set the camera at 1/640 sec, f2.8, ISO 1600, and a bare flash on manual 1/16 power in high speed sync, camera left. I got 4 shots before the flash pooped out -- 10 frames per sec.

Cool series!!!!!!

Thanks -- hopefully I can work at some higher shutter speeds, if the flash can hold out. The timing is the thing -- trying to get a 9 year old to pop a balloon on cue will be a challenge!

Looks good.
You could see if there are any segments of "Things, but very slowly" from "Brainiac, Science Abuse" available online. They were using 4000 fps I think - lots of explosions and things being broken.

Excellent suggestion. That will be great to set the tone. Thank you!

Cool balloon stuff, although she looked a tad uncomfortable at the end!

You know, I read a comment from someone using the 7Ds 60 fps video capabilities for producing some cool slow-mo effects. I thought that sounded pretty interesting.

I am sure. I have seen stuff from the casio camera that shot at that rate, and it is super cool.

Now, how I light it is a different story......
