Reflections from a mirror mounted beneath a table give the illusion that a
disembodied head is sitting on top of the table (talking head). how does this
work? i know that this has something to do with geometrical optics, but i dont
know how to explain it to students from 8 to 13 years old. please help me
explain how the talking head works in an easy way.
