Who needs a day of normal gravity when we can turn the whole city into a giant trampoline? Picture this: the city council runs a "gravity contest" where the winner gets to hang upside down on the city hall roof, the mayor's speech delivered from a balloon, and every street corner becomes a zero‑G obstacle course. We could set up a giant upside‑down Ferris wheel that spins while kids ride on hoverboards, and instead of vending machines, have "sky‑bars" that dispense ice cream as it falls. Let’s add a giant kite‑sized parachute to each child’s backpack so they can glide home, and finish the day with a moonlit dance party on the rooftops—just a little wind to keep everyone in their seats. It’s chaos, it’s laughter, it’s a day worth shouting “Gravity, who?!” out loud.
