I suffered through drinking the bubbly stuff, now it is time to put the empty bottles to use.
I will line them up and shoot a slingshot ball at them. I am not sure how many bottles one ball can kill, I did two of them a while ago.
I am still thinking about wether I will use lead or steel. Lead is more dense and a heavy ball will be smaller, but it will deform and that will reduce the impact. Steel may ricochet, though.
Can't do the test before Friday anyway. It's gonna be fun!
