This is a weird one! almost looks like 2 shots superimposed, I can only assume that the room was not dark enough, so with the the cam on "BULB"
it took an image before the flash fired.

A couple of ideas to add (getting progressively more dangerous);

a Jacobs cracker (or Ryvita) being broken in two?....those things never break cleanly!

A hammer hitting a wet surface?

A hammer hitting and breaking plate glass?

A firework starting (or rocket taking off)?

Another one, which I've thought about since the cricket is on at the mo'...
fitting the trigger with a zoom / tele mic....every single shot would be one with the ball hitting bat, pad or wicket!
Could sit as a spectator enjoying the game without head behind a camera...then leave at the end of the day, knowing you have all the winning shots in the bag!

Unless.................. the duration of the flash was greater than the time it takes for a balloon to burst. This would cause the effect you've shown.

How do I slow the flash down? If I set it to 1/4 power will that do it?

Reducing the power level will give a shorter duration burst. I'm not 100% convinced that my original suggestion is the reason you've seen the double burst/not burst image, it was an educated guess.

Hope Don picks up on this thread. He'd shed some light on things.

Below is from the Nikon SB-800 manual, as can be seen reducing the flash duration reduces power.

1/1050 sec. at M1/1 (full) output
1/1100 sec. at M1/2 output
1/2700 sec. at M1/4 output
1/5900 sec. at M1/8 output
1/10900 sec. at M1/16 output
1/17800 sec. at M1/32 output
1/32300 sec. at M1/64 output
1/41600 sec. at M1/128 output

Ah, I see 'my' card being cut shot is there amongst many others. They are fascinating.

Hi Don
I see you've been busy as well!
Link
I took about 20 shots to get this one, moving trigger around, changing the flash power,and changing aperture. Most of the other shots showed 2 balls (like super imposed shots) but looks like I nailed this one.
