Although it was just that one example they showed of something being dropped in a glass that made me want to do it. The actual video was pretty poor I thought and wasn't actually a particularly good guide as they didn't go into what the best way to actually trigger the flash is.
And I don't have a flash other than the one in my camera so I'll be working with the shutter only.
They were manually triggering the flash when they needed it, there's normally a ready/test button on them that you use, something you can't really do with the pop-up flash built in to a camera.
What you'll find using the in camera flash is, that you'll be limited to shooting at your camera's flash sync speed, which is normally around 1/160 - 1/250. Any higher than this, and you can end up with photos containing big black bars that are actually the inside of your shutter still rolling as the flash fires. However, so long as the only source of light is the flash, this shouldn't matter, as it is going to be much faster, anyway. You simply won't have the luxury of being able to set the shutter open before firing the flash.
