This is one of my favorite 8th grade student take-home activities. I use
it as a question generator, but I am not sure I really understand what is
happening. I have been told it is pyroelectricity but also that it is
static electricity. You need a bandage that comes in a paper wrapper that
must be pulled open by the two tabs at one end. If done in the dark,
light can be seen. Why?
