Gallows 1

They waited, tense and anxious. 100 teen girls, not a single one older than 15, all nude and noosed and standing on milk crates. Each girl had a number painted on her chest. Members of the public were invited to gamble on which would last the longest.
The funds generated from the bets would go towards prison upkeep, of course.

The clock ticked over. The milk crates were pulled out from under their feet. 100 bodies twisted and flexed in mid-air. They kicked and strained towards any kind of foothold, and many girls wrapped their legs around each other in a vain attempt to buy a short gulp of air.

The first to expire were the heavyset girls, followed by the skinny, soft weaklings. They shuddered, eyes rolling up, tongues swollen and portruding. The last to die were the athletic types, their abs and chests shiny with sweat as they fought against the inevitable.

30 minutes had passed before the last girl finally let go, a final death rattle escaping her lungs, eyes half lidded. 100 corpses swung in the wind.
