Every year it seems that Christmas ornaments get fancier and more high tech. Flashing LEDs, recorded messages from Santa, countdown clocks, music-playing, animating, etc.
Have you ever seen an ornament that does a trick? (Not a trick done WITH an ornament, but something sold that will actually do a trick?)
Does such a thing exist?

I am an elemetary teacher. Years ago a student gave me an ornament that looks like a chimney. If you pull a string below a magician holding a Merry Christmas sign pops up. Not sure, but I would guess Hallmark. Not great magic, but greatly appreciated.
