For those interested in making more camera flashbangs, here's how I did it.
What you'll need:-used disposable camera
-tape
-a sharp knife
To get the cameras I used I went to the photo lab at London Drugs and asked for any used disposable cameras they could spare. The rectangular Fujifilm cameras seem to work well.
First, rip all the paper off. There are seven clips in total on each end, the bottom and top of the camera, they need to by pried open with your sharp knife. Don't worry about breaking the clips, they're unnecessary. The camera should open with a little tug, beware of the capacitor (cylinder behind the flash bulb) as it could still be holding a powerful charge! Open, the camera should look like this:
With your knife push together the two copper contacts above the lens (there may be a flash). Get them as close as possible to each other without them touching when you release the pressure.
After you're satisfied with the contacts position, reassemble the camera and make sure it has a good battery. Wrap tape around it making sure not to cover the flash, charging button or the back of the viewfinder. That way, when you charge it with the button you'll see the orange light in the viewfinder to indicate a full charge. Throw and enjoy.
Well, not quite like that
