An open room lay before them, occupied only by a few cobwebs and dust. Upon entering, a phrase is seen on one wall. One of them utters the phrase out of wonder for its meaning, unknowingly activating the room. An eye opens on the wall in front of the poor souls and with a quick flash of light, the last thing heard from the room is heart retching screams... then silence.
I have heard (from an Afghan man that I know) that in Afghanistan, they will construct kites, and then tie or tape pieces of glass and shards of pottery to the kite-strings and have "kite-battles", where they try to use the sharp shards on their kite-strings to cut the opponent's strings.
