Amazing shot Don, I knew you'd love to try this sort of photography.
Very neat idea using foil sheets. (I want a GUN  )I bought another packet of balloons today, if I get time tonight I will take some more shots and changing the flash power.

Well the electrical trigger works Don - love the "grape shot" shot!!! so now you can peel grapes for all of us!!
 Lello, have you any thoughts on perhaps making smoothies from the water/fruit juice bursts and the sound trigger??

Here are the shots from tonight (sorry more balloon shots) last ones
 I find that moving the trigger further away and reducing the flash output I don't get the double exposures. 1st shot the balloon splitting 2nd Balloon filled with talc (made a bit of a mess in bathroom )3rd Just water (sorry about the background I tried foil to reflect light) 4th Water with some washing up liquid (then shaken to make it frothy) As I don't have a pellet gun like Don I improvised, I made a paper airplane with a needle taped to the front to make a dart (you can see it in some of the shots)

Cooking with gas now Lello.
Looked at the pics before reading the post and thought ............ paper airplane with a needle point  ....... good possibilites there too for deliberate inclusion. I really must get round to actually reading the links posted in this thread. Stevies birthday today so off to the shops. I may get time later to do a proper job of my foil trigger so it does not appear in shot. Don

Great set of shots Lello - just a couple of points - were you on auto or manual focus because on Pic 1 rear wallpaper is in sharp focus? On pic 3 the airplane seems like a ghost image - I wonder why? This is a very good thread so thanks for starting it - I'm going to contribute some IR trigger shots as soon as I can get set up - Thanks again.

)As for the ghost image I can assume like my early tries the flash duration was to long!!

I had a play with trying to sort the foil trigger today. Getting consistancy of pellet travel is still eluding me. Attached is a graphic that explains the problem.
So confident was I that .... yes another grape shot, but here the pellet had travelled way out of frame so too far. Bits of grape all over the place, and as I am using 55mm macro I had to wash the camera down afterwards. Important to use a filter as this needs cleaning after each shot. I am quite sure this would even apply if a 150mm lens was used as I even had bits of grape on my workshop clock on the wall opposite.  Well tomorrow is another day in which to try and solve the problem. Don

I think with the set up you have, you could end up with different results every time you try
all depending how the pellet comes through the foil.)I will have think as well. Somehow I do think you'll get there in the end

To all those "shooting grapes" out there - just a suggestion - take one polythene decorators sheet mark circle in appropriate place and star cut from centre so you make a hole with flaps that can just fit over the filter on the end of the lens and secure with velcro/elastic strap. Then hang polythene sheet on frame to provide splatter protection. Saves washing up!!

Brings a new meaning to the term grapeshot from the original one of a type of ammunition! Just a thought Don, the pellet from the pistol will vary each time as the velocity/power depends on the spring and other mechanical bits all working exactly the same way every time and they just won't. They will stay within an 'envelope' of peformance but not be repeatable with accuracy so you might end up going in circles. With your engineering skills you could make something better to fire a projectile with repeatable performance? BTW are you eating lots of fruit salad?
