World Mysteries - Crystal Skulls
They have found 13 of these skulls now and they all continue to defy logic. Dated between 5000-36000 years old.
Who could have made these? I read where they project intense energy when together and exposed to different lights. FN spooky man.
I sure hope those bozos don't unlease some evil curse on mankind or something, with their experiments.
