By using safety goggles as a base, well they are actually safety glasses of the disposable kind, I was able to build up this example of a mask for my students. It is important to think of alternatives and to use what one has at hand. The mechanical department at the school had plenty and since I didnt have any elastic band to attach the mask to the head I found this alternative. A hot glue gun is a wonderful tool when you remember that it exsists. I love the horns on this mask. My daughter just glowed when she wore it.
