Remembered that time at the neighborhood pool we realized that we could release the air bubbles in our swim trunks so they’d get caught in the hollow metal steps of the side ladder and then they were an air reserve so we could 2x our dive

(Or go for a normal dive and then stock up and then when you got near the surface have the older kids hold down your shoulders and inspire oxygen-starvation panic like usual)

Remembered how it inspired us to bring kitchen buckets to the pool and drag them upside-down to under the ladders so they’d be trying to rise to the surface but we could use them as a diving bell like 3x
