I volunteer in an 8th grade classroom and I wanted to bring in some silicon wafers for the students to examine for a "show and tell" session, in order to get them interested in technology. Are there any dangers to the students if they are allowed to handle a wafer? I don't really care if the wafers are damaged, but I don't want to see any student hurt.
I am told that if the wafer breaks, then the edges can be as sharp as a razor blade. Kids being who they are, I might expect there's a non-zero chance of that happening. I wonder if I should just hold the wafer up and allow them to look at it, but not touch it, or maybe I can watch them closely while they handle it to make sure there's no horseplay involved. I could also use something to protect the wafers, around the edges and on the backsides.
