|I used to like to swing as high as I could, basically high enough that gravity, not centripetal (or is it centrifugal?)force pulled the swing down. At the apex, the absolute highest my own momentum would take me, I'd let go of the swing, suspended in air for a brief moment as I slowly drifted down back to the ground - I'd land with a hard thud - especially depending on my height, but the experience was vivid and unbelievable.
I get the same feel on some of those park rides that swing back and forth and eventually up-side-down.
