Question

Why does the escape route window break in a bus or something when they are hit with those tiny orange hammers (emergency hammer?) with metal tips. I mean you can’t even get much force to the hit because the handle is so small you can’t use do a good swing.

Answer 1

You want the pressure on a tiny area of the glass to cause it to break. Those hammers and spring loaded automatic center punches will shatter glass without much trouble.
