I had a couple of Party Poppers left over from the holidays and thought I'd try and catch the streamers in flight.
I used a Trigger Trap trigger with flash adapter to fire a Cactus RF60 Flash gun.
The Trigger Trap device connects to the Audio Jack of a mobile phone and the App gives a number of triggering options including sound.
Setting the sound tolerance so that the camera shutter does not trigger the flash I set up 5 second exposures in a dark room. When I pulled the string to fire the popper the sound of the bang set the flash to fire.
I was impressed by the lack of lag, the Trigger Trap did a good job of capturing the streamers.
I realize that the shot is not very aesthetic but I honestly didn't think it was going to work.
I simply set up a blue sheet of card on an office chair and pointed the flash gun (at 1/8 power)
Now I know that the set up works I might buy some more poppers and set up a more interesting composition.
