Strength

When replacing a broken window today we all learned an invaluable lesson. An object is only as strong as its weakest point.

When cutting glass to fit into the window our glass repair guy used a specialized scoring device. It doesn't cut the glass, it only creates a weak point. When he applied pressure to that weak spot, in this case the scored line, the glass broke perfectly along that line.

What a great sport, he allowed each of the children to score and break some glass.

However, when we applied pressure on the wrong side of the scored glass it didn't break. He pointed out that in film the bad guy always scores the outside glass of some window and then knocks the window in by pushing on that spot. That won't work! You have to push against the opposite of the scored side in order to break the glass.

The BC - I'm still looking for the life lesson.
