Amaze your students with a new twist on the Reverse Mask.
Students will surely marvel at this perceptual puzzler. A glowing face will
mysteriously follow their every move while challenging their understanding of
visual perception. Included are a white face mask, florescent paint set, and
Use a piece of black foam core board as a mask holder for use in a dark room,
or make a "Blackbox", by simply cutting a hole in a cardboard box and displaying
the mask inside. Either way, this is a great demo that will get students asking
questions. Great for a haunted lab display too! Watch the video below...
