Breaking glass balls.

I wanted to see if the cheap "glass" balls from aliexpress would give a decent 'shatter' when hit with a hammer. I set up the sound activated flash trigger in the 'batcave' under the house

In the first image I saw too much spread in the burst because the mic was about 1m away from the noise.


I moved the mic much closer and got this.


Then I tried to get a bounce when it smashed. In some of my breaking-light-bulb photos I found that a short sharp smack with the hammer allowing it to bounce back, got the bulb to lift when it smashed. In this case it simply didn't break.


One more try breaking it then I've had enough - they don't break nicely - obviously cheap junk :)
