I will evaluate the relative mechanical strengths of the two windows I've created so far by dropping a 28.15g steel ball onto them from increasing heights and studying the results. After each drop I will inspect the window for damage. If I find any, I will circle it with a permanent marker to ensure I don't confuse earlier damage with later drops. | I will evaluate the relative mechanical strengths of the two windows I've created so far by dropping a 28.15g steel ball onto them from increasing heights and studying the results.

There was not a huge difference in measured toughness of these two windows. The error bars on this experiment are quite wide, but I'd lean towards maybe window 2 being tougher.
