Description
A science teacher at my school asked if I could design a simple thermometer holder that would clip onto the edge of a beaker and hold the thermometer upright. She showed me one in a science equipment c catalog for about $10 each. I told her I could make one for about $.10 each.
She loved them and said that they worked perfectly. Unfortunately I didn't think to ever take pictures of them before I retired.
