G'day 4u

I have a workshop exercise for students that is this water splash [but remember - no fun allowed ]
The issue here is the speed of the flash -not- the speed of the shutter

If you are indoors -which I suspect you are- then 1/30 to 1/100sec will most likely do.

Lens to water-splash distance is about 1/3 to 1/2 metre [try to avoid splash onto lens]; splash into a shallow dish [1cm deep or so]; maybe try with a medium-sized mirror [or brightly coloured + shiny cardboard] standing behind the water drops to bounce camera-flash back into the water drop from behind the water drop. If you are using a 70-300 lens to zoom in close, you might also need a close-up lens to help with close-focus

may I post you a sample image ...

Success rate for a 'perfect' splash is about 2/100 ... so have lots of fun here

I will, of course, defer to Ozzie_Traveller, but I think that bouncing and diffusing the flash will cause the flash to be less effective and thus, to stay on longer. I think I'd try your sync cord to get different angles, but I'd keep the flash directly on the subject.

I found that video extremely useful for understanding sync speed, flash duration and how you can use a relatively slow shutter speed in conjunction with a flash to "freeze motion" which feels counter-intuitive to how you normally freeze motion on a camera. Essentially if I understand it correctly, you want the flash to be the ONLY illumination that the sensor receives. This means dialing down aperture and maintaining a quick shutter so that the image is essentially black, and then using the flash to illuminate the subject. He explains it better than I could hope to and it's near the end of the video, but I think it's worth watching.
