First, they all flex some, amazingly since they are glass***. I
stsood the window in a garbage can and whacked it about 10 times, each

hard and it finally borke. Like the other two, all the pieces
separated. I don't think they were even very sharp, some how.

It's tempered glass and it's 7 times stronger than non-tempered glass.

And that's good, since I don't have to worry about every little thing
breaking it. I used to fear that at first.
