This pool is deep and circular, lightly cone-shaped. At the bottom is a bubble generator, that spews out one giant bubble of air at a time.

The swimmer dives down, and grabs two straps with his arms, so that he remains in a fixed position, right above the generator.

By pulling the straps, a huge bubble bubbles up. The swimmer releases himself inside it and travels up. As he arrives at the surface, the bubble bursts.

-This pool will be marketed especially to wealthy stock brokers and bankers, at least during their bullish cycle, when their profits are big enough to buy this very expensive pool.

-Amazing footage of dolphins playing with and enjoying their own toroidal vortices [link], is used in this marketing campaign.

Why wouldn't the swimmer, now supported by nothing, just fall through?

Indeed, you need some initial movement. I forgot to mention that he makes an upward movement when he pulls and pushes down the strings. A movement that propels him upwards, right before he gets trapped by the bubble. But that's the sport of it: you need to learn to coordinate that movement.

**What is more: even if the physics of the thing don't work, we can still trick stock brokers into buying it. They love start-ups, even if they're worthless! Bubbles they need, and bubbles they can get.

You could insert stock markets, or property booms, one in each of the bubbles, as a metaphor for something or other.

You shouldn't sell yourself short, [bigsleep].

I wouldn't try to speculate on that.

Similar idea linked, but with added nudity and peril.

Thankfully, today's investors are not so venal, credulous, greedy, foolish, gullible and stupid ...
