I use the strong jet from the middle part of a handheld shower to rinse my hair and it’s always been really counterintuitive to me:
The jet can downright sting when it’s at just the right distance, but the closer I bring it to my head, the less I feel it, until it doesn’t feel like any pressure at all when it’s right up against my scalp.
I’d expect the energy to dissipate, and for the jet to get weaker with distance. Why is it the reverse?

Gravity is accelerating those droplets so close up they have dont have as much velocity as the droplets that have already traveled downward. The formula for momentum is mass x velocity. So those droplets also have more momentum.
