Bang2
I killed the ambient this time, and adjusted the lights a bit (snooted them so more of the light goes where I want it and less is wasted, and propped the right hand one up on a bigger pile of books)
I’m out of balloons now though.
Anywho, it’s been fun playing but I should really start thinking about this weeks “decisive moment” photo! :-)

How about trying it with a balloon dog?
I reckon the effect could be improved by a teaspoon of water, or a little talc in the balloon.
Great stuff though… makes me want to build a sound trigger.
