What technology could make a cricket ball stop and hover in mid-air?

In summary, the conversation discusses a dream where a cricket ball was bowled and stopped in mid-air after bouncing. The question is raised about what technology would be needed to achieve this and whether it is possible to stop the ball's velocity abruptly. The idea of using gyroscopes is mentioned, but it is countered by the conservation of momentum. The possibility of using propellers to turn the ball into a small helicopter is also brought up.

Just had a dream about someone that bowled a cricket ball (spin delivery) and after it bounced when it got to about a meter in height it just stopped dead in the air and hovered. What technology inside of the ball would be needed so that lift force was countered so that it would stop vertically and then another force against the gravitational to keep it in the air. Also is there anyway the velocity the bowler had given to the ball could just be stopped dead somehow.
Was thinking something to do with gyroscopes

Conservation of momentum rules out all internal mechanisms (if you want to stop it for longer than a few milliseconds). If the ball stops and it is not windy, you also rule out aerodynamics. I don't see a way to make that happen with a regular ball in a usual setup. Strong winds in the right directions can make the ball fly in nearly arbitrary patterns.

You could equip your ball with propellers and make it a small helicopter, but I guess that's not what you want.
