Maybe we're all too old for this, but I was wondering how someone sitting on a swing can get themselves so high? I googled around the words "park swing" but couldn't find anything related to how they do it.

Anyone care to explain how to do it?

Inertia, gravity, centrifugal force and mysteries of playfulness.

You actually do some work to push the swing, that sums up to one big shove. Easy to forget because you get carried away.

Many a child has learned how to start a swing from a standstill, with no push.  Learned that way when so small their feet didn't touch the ground and had to learn the chest lean and leg tuck to get the inertia up and the lean back and stretch the legs out comes into play.  Essential for playing alone.

i.e. you do some work, to push the swing.

Guessing it's done by creating a moving series of pivot points, from the top bar of the swing, to your hands, to your waist, to your knees, to your ankles, finally terminating in the swing itself. That's how the forces you generate are transmitted.
