Yah dude. Like a dime sized piece. You dont have to throw it hard either, maybe a half hearted flick of the wrist and BOOM. Its not that loud though.. The window wont fall inside, just shatter. You can push it inside afterwards, ect.
WOW,, you are so Smart. I wish my Fish were as smart as you, maybe they would stop breathing thier own SHIT!!! Why don't you go bust your balls on a railing so you can not mix with the gene pool.
