The rainbow circle of nylon that turned an ordinary PE period into the best day of the school year. Popcorn, cat-and-mouse, and the sacred finale — everyone yanks the chute down behind them and sits inside the glowing dome until it deflates.
A square of plastic, four caster wheels, and two handles — the gym scooter was the best day of the elementary-school month. When the PE teacher wheeled out the stack of them, the gymnasium became a demolition derby, and every kid learned the same two lessons: how fast you could really go, and exactly what it felt like to run over your own fingers.
Once a year, gym class turned into a testing gauntlet: the pull-up bar, the sit-and-reach box, the shuttle run, and the curl-ups counted out by a partner. Do well enough across all of it and you earned the Presidential Physical Fitness Award. Come up short on the pull-ups in front of everyone and you just prayed for it to be over.
