Speaking of glass... in junior high I was eating lunch and heard a big crash and the sound of shattering glass from the hall. So I ran out of the lunch room to see what the commotion was all about only to see a trail of blood on the floor leading up to my friend who was being held near a glass display case. He had a giant slice in his forearm from where the glass had come down and essentially chopped his arm half-way to the bone.
I later learned that my now-wounded friends was playing with some other friends during lunch in the hall. They were heaving each other into the air, and in that specific case, my chopped friend had stumbled and his arm went through a glass case. The weight of the glass above caused the glass to slide down and it sliced his forearm. Remarkably, the slicing did not sever important nerves in his forearm, nor did he lose use of his fingers due to tendon damage. He did suffer some mental issues, affecting his schooling, etc. but I now wonder if it was less the arm chop, and more just because of family life in this state.
Anyway, the potential for shards and cuts is one reason they make those glass cases (and windshields, etc.) with tempered glass these days. So watch out for those antique display cases!
