Or you could just buy a Multiblitz head as used in the original shots you wanted to re-create, but I would say that.

What flash duration will freeze this?!

With mulitple guns you would obviously need perfect sync between them. You should get that if they are all the same model, common triggering etc.
Assuming you need a true 1/2000sec (and you may need less, or more) that would be a 580EX at around 1/3rd power. I think you could do it with what you've got, if you push the ISO.
Try a rough test shoot with one gun, just to see where you are. A lot depends on the exact circumstances, modifier, distance etc etc.
Bought some Einsteins 640's watch this space. Borrowing a manniquin to chuck water at as an experiment, although a faithful model has said I can practice on her!
The Einstein tech info looks impressive so I have a play this weekend.

Ooo looking forward to seeing the pics.
Been playing with some IGBT myself. This is on the to-do list but I'm not supposed to do it until it's warmer.
Meanwhile, here's some rice and flower petals.....

Decided to put give this thread a bump as I've been wondering about doing a few water freeze shots myself. But not really knowing how my heads perform I decided to try a few water filled balloon burst shots.
the set-up
the willing assistant
N.B. he has asked me to make it clear that the wellingtons are his mums!
and the best result
We did have loads of misses like;
and where we missed the pin
I suspect that the water in the burst shot, the water would be traveling significantly faster than in the video that started this post, but I don't know for sure - anyone any thoughts?

Some of these pound shop balloons are quite tough, refusing to burst even when they landed on the pin!
For these last shots I'd turned down the power of the heads to get them to recycle at the burst frame rate of the camera - about 6 frames per second, as a consequence the flash duration would have increased significantly, hence the less frozen appearance.

Ah trailing power cables, water and a child on a ladder.....
Looks like fun.
Couple of things
1. On the motion of the water...it's going to depend on when you press the button. A proper physicist could help us out but I reckon water in a balloon starts out almost stationary and then accelerates very quickly after point of bursting and then slows rapidly. Thrown water will start out with a relatively high speed then slow down. So if you shoot just as the balloon bursts it's moving slower than thrown water. Like this

2. As fun as it looks, I think you'd agree you haven't frozen it.
More balloons, more water, more fun required.

This was a quick trial (sons are demanding more balloon/water action soon) the whole thing from set-up to breakdown was about 1 hour 30 minutes & not really planned, just a spur of the moment thing. All cable joints were raised off the ground and heads moved outside the splash zone - determined by a few trial pops.
Main problems were of course judging the exact moment to press the trigger, trying to stop the willing assistant following the balloon into the picture (usually just got his shadow, plus I think too much water in the balloons
.Now the trial is done will probably try a more thought out 2nd attempt soon although the boys have suggested some other things as well

I was going to have another go today but have no willing helpers - they're all out at play 
The idea this time was to rig up a black background, one light to the front gridded, the other behind and above gelled. This time though, just hang the balloons and pop them.
Not all the missed shots were a total loss, with a bit of manipulation, we have one of those views from space
As I can control the voltage that the heads see, I could potentially reduce the recycle time by using the maximum voltage that the heads can take of 260v (they are multi-voltage heads 100-260v) though as has been pointed out with water and cables perhaps I should be setting the voltage nearer 100v, but that results in:thumbsdown:ZZZzzzzzzzzz recycle times!
